Introduction

When working with Python in Visual Studio Code (VSCode), it is essential to set the PYTHONPATH environment variable correctly. This variable specifies the locations where Python looks for modules and packages. By properly configuring PYTHONPATH, you can ensure that your Python code can access the necessary dependencies.

In this article, we will explore how to set the PYTHONPATH in VSCode and discuss some common scenarios where this configuration is useful.

Why set PYTHONPATH?

Python imports modules and packages using the import statement. When you import a module, Python searches for it in several locations, including the current directory and the directories specified in the sys.path list. sys.path is initialized from the PYTHONPATH environment variable.

If the required module or package is not found in any of these locations, Python raises an ImportError. By setting the PYTHONPATH correctly, you can specify additional directories where Python will look for modules, ensuring that your code can access them.

Setting PYTHONPATH in VSCode

To set the PYTHONPATH in VSCode, you have several options:

Option 1: Launch Configuration

You can set the PYTHONPATH in the launch configuration file .vscode/launch.json. This file allows you to configure settings specific to launching your Python program.

Here's an example of how to set PYTHONPATH in launch.json:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python Program",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "env": {
                "PYTHONPATH": "${workspaceFolder}/mylib"
            }
        }
    ]
}

In this example, we set the PYTHONPATH to include the mylib directory relative to the workspace folder.

Option 2: User Settings

You can also set the PYTHONPATH in the user settings of VSCode. This configuration applies globally to all your Python projects.

To set the PYTHONPATH in user settings, follow these steps:

  1. Open the VSCode settings by pressing Ctrl + , or navigating to File > Preferences > Settings.
  2. Search for "pythonpath" in the search bar.
  3. Click on "Edit in settings.json" under Python > PythonPath.
  4. Add the desired paths to the python.pythonPath setting. For example:
{
    "python.pythonPath": "/usr/bin/python3",
    "python.autoComplete.addBrackets": true,
    "python.analysis.typeCheckingMode": "off",
    "python.pythonPath": "/usr/local/bin/python",
    "python.autoComplete.addBrackets": true,
    "python.analysis.typeCheckingMode": "off",
    "python.envFile": "${workspaceFolder}/.env",
    "python.envFile": "${workspaceFolder}/.env",
    "python.autoComplete.addBrackets": true,
    "python.analysis.typeCheckingMode": "off",
    "python.envFile": "${workspaceFolder}/.env",
    "python.autoComplete.addBrackets": true,
    "python.analysis.typeCheckingMode": "off",
    "python.envFile": "${workspaceFolder}/.env",
    "python.autoComplete.addBrackets": true,
    "python.analysis.typeCheckingMode": "off",
    "python.envFile": "${workspaceFolder}/.env",
    "python.autoComplete.addBrackets": true,
    "python.analysis.typeCheckingMode": "off",
    "python.envFile": "${workspaceFolder}/.env",
    "python.autoComplete.addBrackets": true,
    "python.analysis.typeCheckingMode": "off",
    "python.envFile": "${workspaceFolder}/.env",
    "python.autoComplete.addBrackets": true,
    "python.analysis.typeCheckingMode": "off",
    "python.envFile": "${workspaceFolder}/.env",
    "python.autoComplete.addBrackets": true,
    "python.analysis.typeCheckingMode": "off",
    "python.envFile": "${workspaceFolder}/.env",
    "python.autoComplete.addBrackets": true,
    "python.analysis.typeCheckingMode": "off",
    "python.envFile": "${workspaceFolder}/.env",
    "python.autoComplete.addBrackets": true,
    "python.analysis.typeCheckingMode": "off",
    "python.envFile": "${workspaceFolder}/.env",
    "python.autoComplete.addBrackets": true,
    "python.analysis.typeCheckingMode": "off",
    "python.envFile": "${workspaceFolder}/.env",
    "python.autoComplete.addBrackets": true,
    "python.analysis.typeCheckingMode": "off",
    "python.envFile": "${workspaceFolder}/.env",
    "python.autoComplete.addBrackets": true,
    "python.analysis.typeCheckingMode": "off",
    "python.envFile": "${workspaceFolder}/.env",
    "python.autoComplete.addBrackets": true,
    "python.analysis.typeCheckingMode": "off",
    "python.envFile": "${workspace
