How do I install installer in Python?

The standard way to install installer is by running `python -m pip install installer`. If you are using Anaconda, use `conda install -c conda-forge installer`.

Why causes the 'No module named installer' error?

This error occurs when the python interpreter cannot locate the `installer` package. It is often caused by missing installation or environment mismatch (e.g. installing in global but running in venv).
