Error on install from matplotlib #65

Open jmrfox opened 1 month ago

jmrfox commented 1 month ago

Hi, I am trying to install using venv and pip install uncertainpy. Both Win10 and Debian give me an error when the install gets to the matplotlib portion. This seems to be the important bit:

checkdep_freetype2.c
      src/checkdep_freetype2.c(5): fatal error C1189: #error:  "FreeType version 2.3 or higher is required. You may set the MPLLOCALFREETYPE environment variable to 1 to let Matplotlib download it."
      error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2019\\BuildTools\\VC\\Tools\\MSVC\\14.29.30133\\bin\\HostX86\\x64\\cl.exe' failed with exit code 2
      [end of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for matplotlib

ERROR: ERROR: Failed to build installable wheels for some pyproject.toml based projects (matplotlib)

I copied this snippet from Windows, but a similar thing happens on Linux.

  Rolling back uninstall of matplotlib

Any ideas? Thanks
