VS Code setup for students

Visual Studio Code is free and runs on Windows and Mac, so it is a natural choice when a teacher asks you to code at home. It also confuses beginners, because installing VS Code does not install Python or Java. This guide sets it up the way Microsoft's own documentation describes, on a school-issued laptop or a family computer, then walks through the errors students actually see, with the exact messages from our test machine and the fix for each.

Live teaching since 2020 · 10,000+ students · Python and Java, set up on your own laptop

In short

To set up VS Code for school, install three things: VS Code itself, the language extension (Python, or the Extension Pack for Java), and the language (a Python interpreter, or a Java JDK). Open your project folder with File, Open Folder, pick the interpreter in the Status Bar, and run from the play button. Modern Age Coders teaches Python and Java live to students in the US, in a batch or one to one.

What to install

Three pieces, not one: why VS Code alone runs nothing

The Python tutorial in the VS Code documentation says it directly: "three separate pieces work together to run Python in VS Code." Java works the same way. When nothing runs in week one, check that all three pieces are there.

What each piece does, from the VS Code Python and Java tutorials (read 17 October 2026)
PieceFor PythonFor Java
The editorVS Code, where you write and organize codeVS Code, the same editor
The extensionThe Python extension; the docs note "The extension doesn't include Python itself."Extension Pack for Java; the tutorial needs Language Support for Java by Red Hat and Debugger for Java
The languageA Python interpreter, installed separatelyA Java Development Kit (JDK); the pack "supports Java version 1.8 or above"
An all-in-one optionNone in the tutorialThe Coding Pack for Java bundles VS Code, a JDK and extensions, but "is only available for Windows and macOS"

Is VS Code free for students?

Yes, and not only for students. The VS Code FAQ says "VS Code is free for private or commercial use." There is no student edition to apply for.

Python and the JDK distributions the Java tutorial lists are also free to download, so a working setup costs nothing.

VS Code is not Visual Studio

Visual Studio is a different, larger Microsoft product. If your teacher said VS Code, you want Visual Studio Code from code.visualstudio.com.

The pair is confused often enough that vs code vs visual studio shows up in search suggestions. For a school Python or Java class, VS Code is the one to install.

Installing

Installing VS Code on a school or family laptop

If your school manages your laptop, you may not have an administrator password. The VS Code docs cover that case, and the Mac and old-Windows cases too.

Installing VS Code, from the VS Code setup documentation (read 17 October 2026)
Your computerWhat the docs sayWatch out for
Windows, no admin passwordThe User setup "does not require administrator permissions" and is "the recommended installation for most people""Updates are disabled when VS Code runs as Administrator from a User setup installation."
Windows, family computer"Setup adds Visual Studio Code to your %PATH% environment variable. Restart your console after installation"Run code . in a folder to open it, after restarting the terminal
Mac"Drag Visual Studio Code.app to the Applications folder."Then open it from Applications by double-clicking the icon, as the docs describe
Mac, to use code in TerminalRun Shell Command: Install 'code' command in PATH from the Command PaletteRestart the terminal afterwards
Mac with Apple siliconThe download page lists Universal, Intel chip and Apple silicon buildsUniversal works on both
Windows 7"VS Code version 1.70.3 is the last available release for Windows 7 users"Old laptops need a newer Windows for current VS Code

If Python will not install without admin

The Python tutorial in the VS Code docs offers a route: "If you don't have admin access, an additional option for installing Python on Windows is to use the Microsoft Store."

If the Store is blocked as well, ask your teacher or the school's tech office rather than looking for a workaround; the device belongs to the district.

Mac students: one Python warning

The VS Code docs say "The system install of Python on macOS is not supported." They recommend Homebrew, with brew install python3 in Terminal.

The python.org installer is the other common choice for students. Either way, use a Python you installed, not the one the Mac shipped with.

Python

Setting up Python in VS Code, and the three errors that follow

Follow the steps in order. Each one matches a step in the VS Code Python tutorial, and each error below appears when one is skipped.

  1. Install Python from python.org (Windows) or Homebrew (Mac).
  2. Check it. In a new terminal, run py -3 --version on Windows or python3 --version on a Mac.
  3. Install the Python extension from the Extensions view in VS Code.
  4. Open a folder, not a file. File, Open Folder. In the docs' words, that folder becomes your "workspace".
  5. Create an environment. Command Palette, Python: Create Environment, choose Venv, then the interpreter you installed.
  6. Select the interpreter. Python: Select Interpreter, or click the Python version in the Status Bar.
  7. Create a .py file, type a line of code and save it.
  8. Run it with the Run Python File play button in the top-right of the editor.
A ten-second check · which Python is VS Code using?python
# check_setup.py  (ours) run with Run Python File
import sys
print(sys.version)       # which Python is running
print(sys.executable)    # where it lives on disk

# In the VS Code terminal on Windows, the docs suggest:
#   py -3 --version
#   py -0      (lists installs; * marks the default)
# Our run of py -0:
#   -V:3.13 *        Python 3.13 (64-bit)

If sys.executable does not point into your project's .venv folder, VS Code is using a different Python from the one your packages went into.

Three Python errors and their fixes, from the VS Code Python tutorial
What you seeWhyFix
"ModuleNotFoundError: No module named 'numpy'"The tutorial says it means "the required package isn't available in your interpreter"In the VS Code terminal for that interpreter, run python -m pip install numpy (Windows) or python3 -m pip install numpy (Mac)

Packages vanish when you switch projectsEach virtual environment keeps its own packagesPick the right interpreter in the Status Bar; share setups with pip freeze > requirements.txt

Java

Setting up Java in VS Code, and the file-name error every AP student meets

Java in VS Code needs a JDK and the Java extensions. Our AP Computer Science A course is taught in Java, and its students tend to meet the same two compile errors in their first week.

Broken · the class name and file name disagreejava
// Saved as Greeting.java  (broken on purpose, ours)
public class Hello {
    public static void main(String[] args) {
        System.out.println("Hi from VS Code");
    }
}

// Our run, javac 22.0.1:
// Greeting.java:1: error: class Hello is public,
//   should be declared in a file named Hello.java

In Java, a public class must live in a file with exactly the same name, including capital letters. This is a Java rule, not a VS Code one, so it appears in every editor.

Fixed · rename the file to match the classjava
// Saved as Hello.java  (fixed, ours)
public class Hello {
    public static void main(String[] args) {
        System.out.println("Hi from VS Code");
    }
}

// Our run: javac Hello.java, then java Hello
// Hi from VS Code
// Leave out the semicolon and javac 22.0.1 says:
// Hello.java:3: error: ';' expected

Rename the file in the VS Code Explorer, or rename the class; the two must match. Case matters: hello.java is a different name from Hello.java.

Open the folder, or the language server stalls

The Java tutorial warns: "If you open a Java file in VS Code without opening its folder, the Java Language Server might not work properly." Symptoms are red squiggles everywhere, no Run button, or no code completion.

Fix it with File, Open Folder on the folder that holds your .java files. For a school project with a build tool, open the project's top folder.

When Run is missing: lightweight mode

The Java project docs explain that "Lightweight mode doesn't resolve imported dependencies nor build the project", so it cannot run or debug. Click the Java status item in the Status Bar to switch to standard mode.

If things are still strange, the docs suggest the Java: Clean Java Language Server Workspace command, which rebuilds the language server's view of your project.

Sources, read 17 October 2026: Getting Started with Java in VS Code and Managing Java Projects in VS Code; compile errors from our own run of javac 22.0.1 on Windows 11. We are not connected with Microsoft.

When it still fails

Ten checks when VS Code will not run your code

Our checklist for the evening before an assignment is due. Work through it in order and stop at the first check that explains the error.

  1. Is the language installed? VS Code does not include Python or a JDK. Check with a version command in a new terminal.
  2. Is the extension installed and enabled? Search @installed in the Extensions view.
  3. Did you open the folder? File, Open Folder, not a single file from Downloads.
  4. Is the right interpreter selected? Look at the Python version in the Status Bar and click it to change.
  5. Did you restart the terminal? After any install, open a fresh terminal so PATH is read again.
  6. Read the whole error. Copy the last line into your notes before trying anything.
  7. Java: does the file name match the class? Hello.java for public class Hello.
  8. Java: is it lightweight mode? Switch to standard mode from the Status Bar.
  9. Is the code saved? The docs note that Run Python File in Terminal saves the file automatically; with any other run method, save first.
  10. Try a one-line program. If print("hi") runs, the setup works and the problem is in your code.

About the AI features

Current VS Code versions include AI chat features linked to GitHub Copilot. They are optional, and the VS Code FAQ says that if you disable AI functionality or do not sign in, your data is not sent to the Copilot back end.

While students are learning to read errors, we keep AI chat switched off in lessons, so they learn to fix problems themselves. Check your school's rules before turning such tools on for coursework.

What we will and will not do

A teacher can set up VS Code with you on a shared screen, explain each error, and make sure your own laptop works for the rest of the year.

We do not write or finish graded assignments. We teach the concept so you can solve the assignment yourself.

A first term

What a first term looks like when the setup is done right

Our plan for students who are new to a real code editor. The first two classes deal with setup so it never gets in the way again.

A first term in VS Code (our plan, adjusted for each student)
ClassesWhat the student doesWhat it builds
1 to 2Install, open a folder, run a first fileA setup that works every time
3 to 4Variables, input and outputReading the terminal, saving often
5 to 6Decisions and loopsUsing the debugger and breakpoints
7 to 8Functions or methodsSplitting code across files
9 to 10A project with a package or classEnvironments, imports, file names
11 to 12Version control with GitCommitting work from inside VS Code

Middle school

In our classes, students in Grades 6 to 8 start with Python, where one file and one play button go a long way.

High school

Students heading for AP Computer Science A add Java in the second term with us, in the same editor.

College

We have college students set up one environment per course from day one, which saves a lot of grief at midterms.

For the AP course itself, see AP Computer Science A online classes; for Java outside the AP track, Java classes for teens; and for choosing an editor at all, our post on Java IDEs for beginners.

Where a student is

Four stages of working in a real editor

From fighting the setup to forgetting it is there.

Stages with VS Code (ours)
StageWhat it looks like
1. InstallerVS Code is installed, but nothing runs yet
2. RunnerRuns single files with the play button
3. OrganizerWorks in folders, environments and projects
4. DebuggerUses breakpoints and reads errors before searching

For parents

If your child is stuck at stage 1, it is almost never their fault: one of the three pieces is missing. Once all three pieces are in place, the setup keeps working.

On a school-managed laptop, some installs are blocked on purpose. Check with the school before working around anything.

For students

Always open the folder. Half of all VS Code mysteries disappear with that one habit.

Look at the Status Bar. It tells you which Python or which Java mode you are in.

Questions students ask

VS Code setup: common questions

Is VS Code free for students?

Yes. The VS Code FAQ says VS Code is free for private or commercial use, so there is no student version to apply for. Python and the free JDK builds the Java tutorial lists cost nothing either.

Why is VS Code not working with Python?

Usually one of three pieces is missing: VS Code, the Python extension, or Python itself. The extension does not include Python. Install Python, restart the terminal, then choose the interpreter with Python: Select Interpreter.

How do I select the Python interpreter in VS Code?

Click the Python version shown in the Status Bar, or open the Command Palette and run Python: Select Interpreter, then choose your project environment or the Python you installed.

Why does VS Code say No module named numpy?

The package is not installed in the interpreter VS Code is using. In the VS Code terminal for that interpreter, run python -m pip install numpy on Windows or python3 -m pip install numpy on a Mac.

How do I set up Java in VS Code?

Install a JDK and the Extension Pack for Java, or on Windows and macOS use the Coding Pack for Java, which bundles both with VS Code. Then open the folder that holds your .java files.

Why does Java say class is public, should be declared in a file named?

A public class must be in a file with exactly the same name. Our run of public class Hello in Greeting.java failed for that reason. Rename the file to Hello.java, matching capital letters.

Can I install VS Code on a school laptop without admin rights?

The VS Code docs say the Windows User setup does not require administrator permissions. Your school may still block installs, so check with your teacher or school tech office first.

Will you do my coding assignment?

No. We help you set up your tools and teach the ideas so you can finish your own assignment. We never complete graded work.

What times are classes for US students?

Weekdays or weekends, flexible. Choose your batch, or for a very personalised plan choose 1-on-1 at your convenience, weekend mornings or weekdays.

How much do Python or Java classes cost?

The first lesson is free. After that you pay monthly for live lessons, and the fees section on this page shows the amount in US dollars.
