pdfgui "no module named 'wx' error" for pip installed diffpy.pdfgui==3.1.0rc4 (Apple M1)

[bobleesj]

As instructed by @sbillinge, I tried the following steps:

> conda deactivate
> mamba create -n pdfgui-test311 python=3.11 
> conda activate pdfgui-test311
> pip install diffpy.pdfgui==3.1.0rc4
> pdfgui

Pip installation works. But, I get the following error when I type pdfgui

imac@imacs-iMac ~ % pdfgui                                   
Traceback (most recent call last):

ModuleNotFoundError: No module named 'wx'

I checked that the regular installation procedure worked:

CONDA_SUBDIR=osx-64 conda create -n pdfgui39 python=3.9
conda activate  pdfgui39
conda config --env --set subdir osx-64
conda install -c conda-forge diffpy.pdfgui
pdfgui

@bobleesj Thanks. When you pip install the package you would also like to install all the requirements. This is not necessary when installing from Conda-forge because it will automatically install everything for you. In this case wx means the wxpython package which is one of the requirements.
A good way to install requirements easily is to cd to the package dir then run Conda install --file requirements/run.txt (depend on what you want to do you might also want to install test.txt or build.txt).
I guess you want to test running pdfgui with the latest pdffit2==1.4.4rc1. So after installing all of the requirements you then (or before installing requirements) uninstall the original pdffit2 you get from Conda-forge and then do the pip install. After this run Conda list to check if everything is correct.

@Tieqiong Thanks for the answer. I cloned the latest main branch from diffpy.pdfgui and then ran Conda install --file requirements/run.txt

I get the following dependency error fonttools >=4.22.0 for Python 3.12 (M1).

Pins seem to be involved in the conflict. Currently pinned specs:
 - python 3.12.* (labeled as 'pin-1')

@bobleesj This is very strange, as on my Mac it install fonttools == 4.53.1 for me. Maybe try uninstall it and then install? It could be that you had a older version installed somewhere before?
