(Question) What to do if a packages requirements are not quite known (yet) - to answer myself #57

Open 573 opened 4 years ago

Let's say I have a list of requirements in a mach-nix.mkPython block and the build complains along the lines of

ERROR: Could not find a version that satisfies the requirement packaging (from Sphinx==2.3.1) (from versions: none) ERROR: No matching distribution found for packaging (from Sphinx==2.3.1) builder for '/nix/store/y8y8x98zyyczp66gcy2pv7ds3bxadl8b-python3.7-sphinx-2.3.1.drv' failed with exit code 1

I already have providers = { sphinx = "nixpkgs"; };.

See log.

Just add Sphinx as in

requirements  = ''
  Sphinx
'';

That's strange. It means that there is some requirement specification of a package which is not recognized by nix, but by the python installation procedure. This needs more investigation.

I cannot say which other package on my list introduced the sphinx requirement. When getting the error (log above) I searched the internet for requirements sphinx had found no requirements.txt and then more or less copied what was listed here

Could you provide the original list of requirements that caused the error from the first post?

By the end of the week.

The list of requirements is as in this file. The rest of my config as mentioned in this issue comment (#58).
