Abjad installed but assert error

THANK YOU for putting this together Marc.

I receive this error in the test file copied from the command line.

Python 3.9.1 (v3.9.1:1e5d33e9b9

I believe I have Abjad installed, since I ran the following:

pip3 install --user abjad==3.1

and see the following:

Requirement already satisfied: abjad==3.1 in …

How can I overcome this issue?

Hmm… maybe you have multiple versions of python3, and installed abjad to the wrong one? What happens if you simply open up the python interpreter and type import abjad?

Hi so this happens:

import abjad
Traceback (most recent call last):
File “”, line 1, in
File “/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/abjad/init.py”, line 13, in

This worked

sudo pip3 install --upgrade pip
pip3 install --user --upgrade matplotlib
pip3 install six
