Error in running tests on local machine

Python Help

Hello everyone,
I am trying to setup a clone of MSS on my local machine, I have installed all the dependencies but I get this error when I run the repo coverage test:

PS: Sorry for throwing all the code straight up.

This results in terminating the tests even before running:

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Interrupted: 9 errors during collection !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I would really appreciate some help in understanding why the modules cannot be imported.
Thanks in Advance.

Pytest may be hiding some details of the error, I am not sure on that.

What is the error when you try to import array from the python prompt of the version you are using?

Then check if array._UnicodeTypeCode exists.

3

Yes, array is imported just fine but the latter returns attribute error:

import array

if array._UnicodeTypeCode:
    print(0)

if array._UnicodeTypeCode:
AttributeError: module 'array' has no attribute '_UnicodeTypeCode'

Is it a necessary module that needs to be there?

4

The array module is part of python’s stdlib.
I cannot find a version of python that every had array._UnicodeTypeCode.
I wonder if the code expects to use an array module that is not the python one?

At this point I would ask the author of the code what is going on.

5

Okay, I’ll ask them.
Thanks for the response! Much appreciated.

The author just told me to use python 3.11 for develop branch. After installing the required version, I tried starting the app, the terminal shows :

Traceback (most recent call last):
  File "C:\Users\Gaurav Sharma\Desktop\OpenSource\mss\mslib\msui\msui.py", line 43, in <module>
    from mslib.msui.msui_mainwindow import MSUIMainWindow
  File "C:\Users\Gaurav Sharma\Desktop\OpenSource\mss\mslib\msui\msui_mainwindow.py", line 41, in <module>
    from slugify import slugify
  File "C:\miniforge\envs\mssdev\Lib\site-packages\slugify.py", line 5, in <module>
    from array import _UnicodeTypeCode
ImportError: cannot import name '_UnicodeTypeCode' from 'array' (unknown location)

I get the error is to not being able to import this _UnicodeTypeCode. Could there be a possible solution to this?

7

Ask the author to fix their code. _UnicodeTypeCode was at best an undocumented internal attribute that got removed, if it was ever part of the stdlib. It seems to only be part of typeshed and never available at runtime.

8

Which version of python-slugify is this?

Have a look if you can update to 8.0.4, e…g. mamba update python-slugify
https://anaconda.org/conda-forge/python-slugify/

We can pin python-slugify to a version without that bug.
