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:
- Open the VSCode settings by pressing
Ctrl + ,
or navigating toFile > Preferences > Settings
. - Search for "pythonpath" in the search bar.
- Click on "Edit in settings.json" under
Python > PythonPath
. - Add the desired paths to the
python.pythonPath
setting. For example:

"python.autoComplete.addBrackets": true,
"python.analysis.typeCheckingMode": "off",
"python.pythonPath": "/usr/local/bin/python",
