pip-uninstalling rpm-installed packages should not work, that is expected. The error message is cryptic, we have opened https://github.com/pypa/pip/issues/8954 already. Hi Miro In my opinion, the issue here is that if the custom migrate from RHEL8 to RHEL9, when the custom's environment need chardet < 4.0 (specified by requirement in python project), the installation will fail in RHEL9 while it works well on RHEL8. I do not think it is acceptable. > I do not think it is acceptable.
I respectfully disagree. If this was not acceptable, we would not be bale to update any Python package ever and we would be stuck with the RHEL 8 versions for eternity.
If a customer specifies Python requirements in projects, such as "chardet < 4.0", they can use PyPI (or their internal package server) to fetch and install the packages into a virtual Python environment. RHEL offers only a very limited set of packages in a very limited set of versions (usually one version per package for a specific Python version).
Uninstalling system packages with pip and replacing them with custom versions isn't (and never was) a supported use case. In fact, users can brick their system when they do that.
Before we go any further: What **exactly** do you try to accomplish here? I don't think uninstalling chardet is the end goal here, is it?
Hi Miro, Actually i can create a virtual env to install the pip package chardet, just a little curious about the system behavior change from RHEL8 to RHEL9. Feel free to close this bug since there's been a pip issue to track the log problem. Thanks for your explanation Upstream PR: https://github.com/pypa/pip/pull/9949 Let's wait a bit for their feedback before we backport it. It was merged upstream, so we can backport (or rebase after release) It should first go in Fedora Rawhide and 34.
