Common Issues and Troubleshooting when Installing Python on Mac

Common issues that arise while installing Python on Mac are as follows:

1)“command not found: python” Error: There are situations where Python command is not recognised, which is usually caused by the installation not being in the system’s path. It is possible that you’ll have to find the Python binary and make changes to your shell profile (.zprofile, .zshrc) accordingly.

2) Out-of-date Python Version: In case you are using an outdated version (like 3.9.x), then you probably do not have the latest functions or compatibility with the up-to-date packages. It is good practice to install the newest stable Python version and modify your PATH or version-manager settings accordingly.

3) Using the System-installed Python: macOS typically comes with a system Python that is meant for internal use by the OS and development tools. If you use this version for your projects, you might face conflicts. It is a better practice to install a separate version (through the official website, Homebrew, or a version manager).

4) Missing Pip or Pip Command Errors: Even with Python installed, you might still encounter errors such as zsh: command not found: pip. This typically indicates that pip is not in the PATH or that you are using a different Python installation. Often, the problem can be resolved by running python -m ensurepip --upgrade or by making sure your version manager is set up properly.

5) Package Installation Errors (e.g., “error: externally-managed-environment”): If you install packages globally without isolation and a version manager, it can create version conflicts. The recommendation is to either set up a virtual environment with venv or use pyenv as a version manager, thus keeping dependencies isolated for each project.
