Python path on windows

Question

I have two installations of Python on a corporate Windows computer. One from the Anaconda distribution:

C:\Users\Me\AppData\Local\Continuum\anaconda3\python3.exe

Another one from a corporate installer:

C:\Users\Me\AppData\Local\Downloaded Apps\WinPython\python-3.4.3\python.exe

If I type "python" in the default "cmd" terminal or in the Git Bash, it says "command not found". Probably for the same reason, Jupyter does not allow me to create a Python 3 notebook. How do I set the paths so that Python is available system-wide? I prefer the Anaconda distribution's Python.

EDIT: Creating a new user variable PYTHONPATH and setting it to C:\\Users\\Me\\AppData\\Local\\Continuum\\anaconda3\\ via Windows System Properties does not have an effect.

Answer 1

This answer describes step-by-step an approach that worked for me. However, as eryksun notes in the comment, the additional variable should not be named PYTHONPATH . I renamed it PYTHON , which works.

Strangely, adding the paths directly to the PATH variable did NOT work.

Answer 2

You have to add the path of your installation to the Environment variables. Simply go to the System Properties / Environment Variables / From there, create a new system variables and add your python path.

Answer 3

In the system variable section select the Path variable. Add new variable C:\\Users\\Me\\AppData\\Local\\Continuum\\anaconda3\\ as environment variable in your advanced System Settings. This is from where your system will invoke the python interpreter.
