So I'm trying to get qiskit to work on my system (arch linux) but I'm having trouble installing qiskit, specifically qiskit-aer. I've seen several other posts with similar issues suggesting that I downgrade python. To do this I'm using pyenv running python 3.8.7 so if I run python -V i get the output python 3.8.7. Still when i try to pip install qiskit i get this gigantic error that i'll leave below:

I noticed that even running pyenv if i do pip --version i get the output pip 21.3.1 from /home/gustavo/.local/lib/python3.10/site-packages/pip (python 3.10) i don't know if that has anything to do with it. Any help getting this thing to work is much appreciated.

   command: /usr/bin/python -u -c 'import io, os, sys, setuptools, tokenize; sys.argv[0] = '"'"'/tmp/pip-install-hdx4vhk7/qiskit-aer_a40dd1ec77a24f92ad7ab25442a2ee29/setup.py'"'"'; __file__='"'"'/tmp/pip-install-hdx4vhk7/qiskit-aer_a40dd1ec77a24f92ad7ab25442a2ee29/setup.py'"'"';f = getattr(tokenize, '"'"'open'"'"', open)(__file__) if os.path.exists(__file__) else io.StringIO('"'"'from setuptools import setup; setup()'"'"');code = f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' bdist_wheel -d /tmp/pip-wheel-yvnffenf

  • It seems that qiskit is requiring BLAS matrix library, but it is not listed as a Conan dependency, maybe it is vendored in qiskit, or assumed to be in the system because there was not a BLAS package in ConanCenter some time ago? (it seems there is at least openBLAS now: https://conan.io/center/openblas) – drodri Dec 17 '21 at 15:18
  • Thanks for the suggestion, i installed openblas and now it installed just fine apparently, but i'm now having trouble importing qiskit-aer, it prompts me to pip install qiskit-aer, but that is already installed. Trying to import it gives me the error `MissingOptionalLibrary`. Any leads? – Gustavo Schranck Dec 17 '21 at 16:27
  • I managed to figure it out, i switched the openblas package for openblas-lapack package and now it works just fine, I'll write an answer and close this post, thanks again @drodri much appreciated! – Gustavo Schranck Dec 17 '21 at 16:52

Thanks to the suggestions by @drodri in the comments of the original post I managed to get a solution. Basically I was missing a the openblas dependency. With that i managed to get qiskit installed, although qiskit-aer was not working when I tried to import it. To fix that i just needed to install openblas-lapack package (that required me to uninstall openblas because of package conflicts) and now everything's working correctly. Thanks to @drodri once again
