I tried to import kiwisolver in Atom on MacOS Sierra, and I get the error it is not found:

Input:

import kiwisolver as kiwi

Output:

Traceback (most recent call last):
File "/Users/Kev/Documents/Uvic/Python/PHYS 321B/A6Q5&6_Coupled_Oscillators_Matrix.py", line 3, in <module>
import kiwisolver as kiwi
ModuleNotFoundError: No module named 'kiwisolver'

The problem is that it is already installed: 

w134-87-183-190:~ Kev$ sudo python -m pip install kiwisolver

Has anyone encountered this issue? How do I resolve this issue? I need it to run Matplotlib.

Edit: I'm using Python 3.6.

w134-87-183-190:~ Kev$ python -V
Python 2.7.10

w134-87-183-190:~ Kev$ python --version 
Python 2.7.10

w134-87-183-190:~ Kev$ python3 --version 
Python 3.6.4

In atom, I have this in my config.cson. All three paths give the same error:

runner:
    scopes:
      # python: "/usr/local/bin/python3"
      # python: "/Library/Frameworks/Python.framework/Versions/3.6/Python"
      python: "/Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6"

After 3+ hours of agony, the solution turned out to be quite simple.

Uninstall Kiwisolver: 

pip3 uninstall kiwisolver

Then reinstalling Kiwisolver:

pip3 install kiwisolver

If you're on a Mac try running this, as you might have some permission issues:

pip3 install kiwisolver --user

  • It's telling me: `Requirement already satisfied: kiwisolver in /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages Requirement already satisfied: setuptools in /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages (from kiwisolver)` – Kevin Mar 27 '18 at 21:29
  • @Kevin Maybe you have installed it for a different user (with sudo, for example)? Or you have installed it in a local or non-standard package directory? – baduker Mar 27 '18 at 21:33
  • I have it installed in: `/Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6` – Kevin Mar 27 '18 at 21:41
