How can I set up a virtual environment for Python in Visual Studio Code?

In my project folder I created a venv folder:

python -m venv venv

When I run command select python interpreter in Visual Studio Code, my venv folder is not shown. I went one level up like suggested here, but Visual Studio Code doesn't see my virtual interpreter.

What did I miss?

It sounds like Visual Studio Code (VS Code) is not detecting your virtual environment automatically. This can happen for a few reasons, but the good news is that you can resolve this by either ensuring proper configuration or manually selecting the virtual environment.

Here are the steps to help VS Code detect and use your virtual environment:

1. Ensure the Virtual Environment is Activated

Before starting with VS Code, make sure your virtual environment is properly activated. You can do this in your terminal:

On Windows:

venv\Scripts\activate

On macOS/Linux:

source venv/bin/activate

This will activate the virtual environment and ensure that Python within the venv is used.

2. Manually Select the Virtual Environment in VS Code

If VS Code does not automatically detect the virtual environment, you can manually configure it to point to the correct Python interpreter.

a. Open the Command Palette

In VS Code, press Ctrl + Shift + P (Windows/Linux) or Cmd + Shift + P (macOS) to open the Command Palette.

b. Search for "Python: Select Interpreter"

Type and select Python: Select Interpreter.

c. Look for the Virtual Environment

If your virtual environment appears in the list, select it. If it doesn’t appear:

  1. Browse for the Python interpreter manually: In the Command Palette, select Enter interpreter path and then choose Find.

  2. Navigate to your venv folder: Go to the folder where your virtual environment is located, and select the python (or python3) executable in the venv directory.

    • On Windows: venv\Scripts\python.exe
    • On macOS/Linux: venv/bin/python

3. Check Python Path in settings.json

Ensure that your project's settings in VS Code point to the correct Python interpreter. You can set the interpreter path explicitly in the workspace settings.json file.

  1. Open the Command Palette and type Preferences: Open Settings (JSON).

  2. Add the following line, replacing the path with the actual path to your virtual environment’s Python interpreter:

    "python.pythonPath": "path/to/venv/bin/python"

    For example:

    • Windows: "python.pythonPath": "C:/path/to/your/project/venv/Scripts/python.exe"
    • macOS/Linux: "python.pythonPath": "/path/to/your/project/venv/bin/python"

4. Restart VS Code

After making these changes, close and reopen VS Code to ensure the virtual environment is detected correctly.

5. Check for Python Extension

Make sure you have the Python extension installed in VS Code, as it provides features like selecting the Python interpreter. You can check this by searching for the Python extension in the Extensions view (Ctrl + Shift + X).

By following these steps, you should be able to manually configure or troubleshoot why your virtual environment is not being detected in Visual Studio Code.
