How to install PySide6?

Question

I am following the documentation in here

First installation issue (Solved):

It is suggested to install pyside6 in a virtual environment, so I follow each step.

python -m venv env

env\Scripts\activate.bat

pip install pyside6

However, I get the warning prompt:

"Could not find a version that satisfies the requirement pyside6 (from versions: ) No matching distribution found for pyside6"

I tried installing other packages like pandas to check if pip was the problem. But there was no issues installing it into the environment.

Update: as mentioned by @eyllanesc the python version must be >=3.6 and must be 64-bit python (not mentioned in the doc page I looked at)

Second installation issue:

However, a related issue to installing PySide6 is when I try to install PySide6 with other packages in a conda environment using pip (PySide6 is not available in conda yet).

Using the anaconda prompt,

conda create --name test_env python=3.9.5 then

pip install PySide6

At this point running PySide6 modules will have no problem. But if I add certain libraries then there will be an issue:

conda activate test_env

conda env update --file test_env.yml #includes pandas, matplotlib, seaborn, and requests

The error below will show up:

I tried reversing the order by building the conda libraries first:

conda env create --file test_env.yml then

pip install PySide6

The same error will show up.

So upon installing each package one by one after installing PySide6, I learned PySide6 starts to fail and show the error after I do conda install matplotlib or conda install seaborn (as it installs matplotlib as well)

Update: upon checking further, there is a compatibility issue with matplotlib and PySide6 at the moment as shown here

Answer 1

For anyone who's still paying attention, conda install pyside6 now works.
