Why Am I Getting a 'ModuleNotFoundError' in VS Code Even After Installing the Module?

ModuleNotFoundError in VS Code despite Module Installation

When debugging Python code in VS Code, you may encounter a "ModuleNotFoundError" despite having installed the required module. This error usually arises due to Python not recognizing the installed module.

To resolve this issue, consider the following steps:

• Reload VS Code: Press [Ctrl] [Shift] [P] and select "Reload window."
• Use a Virtual Environment: Ensure that the module is installed within a virtual environment.
• Install Module Correctly: Use the recommended pip installation method: [python3 -m pip install new_module] (replace "new_module" with the module's name).

If the error persists, edit your system to use venv for package management and create a new virtual environment for each project.

Edit for Debian 12

Newer versions of Python (e.g., in Debian 12) require the use of virtual environments for package management. Always create a virtual environment for new projects and install packages within that environment. To deactivate the active virtual environment, use the "deactivate" command.

Additional Considerations

Verify that the python venv module is installed on your system. For Debian-based systems, run the following command to install it:

$ sudo apt install python3-venv
