    I am trying to install gensim to do some topic modelling. But I keep having the same problem, which is that it can't prepare metadata when collecting from scipy. I hope maybe you guys can help.

    Here is the error-code when I write "pip install gensim":

    note: This error originates from a subprocess, and is likely not a problem with pip.
    error: metadata-generation-failed



    I have tried these things because other people have similar problems:

    • Installing Visual Studio with Desktop Development with C++
    • I read it could be something with the versions of scipy and python, but I can't get i working. Maybe I did it the wrong way
    • I tried "conda install gensim" which gave another error about something with python versions not being compatible
    • Tried uninstalling python entirely and then install again with Anaconda
