Problems installing using Pipfile on Windows #86

Closed sadlermike closed 3 years ago

sadlermike commented 3 years ago

Describe the bug When installing pynite using the Pipenv file, you get errors when trying to import the package.

The problem appears to be that pip installs the package to ...\site-packages\pynite, but the package's init file contains the line:

from PyNite.FEModel3D import FEModel3D

This appears to be a case sensitivity issue - is the package intended for Linus use only?

To Reproduce Steps to reproduce the behavior:

  1. Copy pip install name from https://pypi.org/project/PyNiteFEA/
  2. Add the line "PyNiteFEA = "*"" to the Pipfile
  3. Run pip upgrade
  4. Attempt to import pynite using either "import pynite" or "import PyNiteFEA" or "import PyNite".

Expected behavior The ability to import elements of pynite

I'm not familiar with using pipenv to install. But if you use pip install PyNiteFEA as listed on PyPI, it should install on Windows. Once installed, it can be imported under the name PyNite as seen in the init.py. The imported names PyNite and FEModel3D are case-sensitive, like all module names in Python.

Does that help? If not, maybe you can give more detailed steps to recreate the problem?

Hello @tamalone1 ,

Thanks for that. I've just had an experiment, and the problem seems to have been that I absentmidedly installed the other pynite (https://pypi.org/project/pynite/), and what I think happened was that when pipenv went to install PyNite, it found the existing pynite folder, and used that.

When I deleted the 'pynite' folder, it installed correctly.

Thanks for your response!

Best regards,

Mike
