pip installation on windows fails with 'ValueError: path cannot be absolute'
trafficstars
Repro:
Windows 10
conda activate my_env
installing mingw following these instructions
pip install f90wrap
ValueError: path '/Users/jameskermode/.pyenv/versions/3.6.6/lib/python3.6/site-packages/numpy/f2py/src/fortranobject.c' cannot be absolute
Installing from source with python setup.py develop seems to work fine however.
Here is a backtrace for the above error

Hello, I just ran in the same exact problem (Windows 10, MINGW-w64) with pip install f90wrap.
Using pip install git+https://github.com/jameskermode/f90wrap worked fine.
Ok, thanks for reporting. I’ll try to make a new release soon which should fix this issue.
Well, the installation did not raise any error, but I got the same problem I always get with f2py on Windows: the DLL files are created in a .libs folder next to .pyd files, and Python complains with
ImportError: DLL load failed while importing sizeof_fortran_t: Le module spécifié est introuvable.
Simply moving manually the DLL file out of the .libs folder solves the issue. Which makes me realize that this issue has been updated since the last time I checked it out. Looks like there is now a real solution.
