Why Am I Getting a 'ModuleNotFoundError' in VS Code Even Though the Module is Installed?

ModuleNotFoundError in VS Code Despite Installed Module

You're encountering a "ModuleNotFoundError" in VS Code, despite installing the required module. Here's why:

1. Check Installation Environment

Ensure that the module is installed within the same virtual environment or interpreter used by VS Code. Create and activate a virtualenv to isolate your project packages:

python3 -m venv env
source env/bin/activate

2. Install Module Using Recommended Command

Use the proper pip command to install modules:

python3 -m pip install new_module

Replace "new_module" with the actual module name.

3. Restart VS Code and Reload

Restart VS Code and reload the window using Ctrl Shift P and select "Reload Window." This action refreshes VS Code's module detection and autocompletion.

4. Consider Separate Virtual Environment

For newer distributions like Debian 12 with Python3, always create and use a virtual environment to manage packages. This ensures package isolation and prevents system-wide interference.

Additional Notes:

• Python venv module requires installation before use. On Debian-based machines, run:

  $ sudo apt install python3-venv

  Copy after login

• Deactivate the virtual environment when no longer needed using:

  deactivate

  Copy after login

By following these steps, VS Code should recognize the installed module and autocompletion should function properly.
