    Default Unable to install any python3 modules using pip command

    Hi,
    It seems like python3.7.3 in Tumbleweed can't download modules from pypi.org; It was working great about month ago.

    here's my error message :
    Code:

    I did try to add --trusted-host option but not working as expected.
    I would appreciate any help.
    Thanks!

    Looks like the issue is with the SSL Certificate on Pypi.org.

    The error message "There was a problem confirming the ssl certificate:" indicates the same. Please try to do the same after a few hours. it'll work most probably. Otherwise, you can use the VPN to connect to the PyPi servers to download the modules and see if the issue arises or not.

    I had same problem. I did try many thing such like --trusted-hosts, install more recent openssl, but nothing works.
    and I found this link; It solved the problem.

    Default Re: Unable to install any python3 modules using pip command

    If you're referring to the part about updating pip and pip3 from PyPi,
    I think that ha always been a soft requirement for as long as I can remember... The version from OSS will usually work, but it's not guaranteed to do so or do so well.

    Bottom line, if you've never installed from PyPi before or haven't for a very long time, the first thing you should do is update your pip and pip3.

    The other part in the thread about installing PyPi packages into a User directory can be recommended, but shouldn't ordinarily be a must-do requirement. I suppose whether you do this is partly whether you intend to simply run python apps or intend to build apps... Running pre-built apps is usually a normal, User level function, but running system level apps and writing code is normally reserved for elevated permissions.
