Workarounds

  1. 97% success Install in the correct virtual environment: pip install numpy (with venv activated)

    python -m pip ensures pip matches the Python interpreter

Dead Ends

Common approaches that don't work:

  1. Installing globally with sudo pip install 75% fail

    Installs in system Python which may be different from your project's Python

  2. Adding the module to sys.path manually 70% fail

    Fragile; path changes break the import
