Please provide a pyqt5 package

[flylover88]

The pip package is called pyqt5, so trying

conda install pyqt5

results in an error, causing me forget that I should use

conda install pyqt
# or
conda install pyqt=5

Thank you!

Adding the version to the package name is a terrible hack to "kind of" allow both versions to be installed at the same place. Conda-forge is not PyPI and conda is not pip, so some differences are expected. With that said, we never got a complaint before. If this is really something the community wants we can try a meta package that is called pyqt5 and installs pyqt >=5, but I'm not so sure that is a good idea.

I've been bitten by this name difference in a number of different projects where we try to share requirements files for pip-based and conda-based test environments.

While it would make our group's lives easier to have the proposed metapackage, I've never opened an issue since I think the assertion that "conda-forge is not PyPI" is compelling - enough that the feedstock authors shouldn't feel the need to match it.

The challenge is that pyqt is not a normal pip package. It pulls in many C dependencies, which can easily cause conflicts on a person's computer making their environment unrecoverable.

I've spent at least 30 minutes trying to recover an environment before giving up and finally rebuilding it because I accidentally typed pip install pyqt5.

The other thing to note, is that pyqt5, is what the import is called. You don't import pyqt, you import PyQt5. So having the conda package name match it seems to make sense.

It is rather strange that pip list doesn't find the package, but pip does recognize it as already installed

Thanks for posting this. I also accidentally typed pip install pyqt5 at first and was going crazy trying to figure out why conda wasn't working.
