@stonebig as for a solution, you'll need to update the requirement to not include the +dummy part.
I did it. I had the precise error message with the position. Just reported the "+" no more tolerated in case it was to consider a bug
so me puting only the first line of the error miss-leaded you. you may close this one
@stonebig what command did you use precisely? Because when I tried, the pip install command above did not report the error details.
... time to figure out I had temporarly fell back to pip-24.0. so with Pip-24.1b1, the method is
...WPy64-31300b1b\scripts>python -m pip install --pre --no-index --trusted-host=None --find-links=...\packages.srcreq -c ...\constraints.txt six
generating:
ERROR: Invalid requirement: 'python-hdf4>=0.10.0+dummy' (from line 437 of ...\constraints.txt)`
and no line below. you are right: I allucinated the "detailed" error message, I don't see it either
