Solved: pip/Python modules solution for Sept 2019 update

lorraine5RWGT · ‎09-26-2019

Problem

----------

In the new update, I couldn't install modules through pip the way that has usually worked for me:

(this is in Fusion's Python interpreter)

import pip
pip.main(['install', numpy])

I just get this now:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 'pip' has no attribute 'main'

Solution

----------

I found some pip exe's in the Scripts folder that Fusion's python.exe is in.

I was able to run pip this way in Windows PowerShell to install, e.g. numpy.

> .\pip3 install numpy

`pip.main` still doesn't work in the Python interpreter, but importing numpy does -- voilà

Edit: The pip3.exe probably exists because I ran get-pip.py first (https://bootstrap.pypa.io/get-pip.py)
