No errors

Steps to reproduce/example code:

On Windows 10, I have a test python file containing only one line saying "import arcade". It compiles under python 3.8

I have run:
pyinstaller --noconfirm --onedir --console "C:/Playpen/Software/soxviewer/test.py"

Running the created executable I get a library load issue.

Shapely has been removed from arcade so the new v3.x.x does not use it.

In the meantime, uninstalling shapely should help, since arcade 2.6.17 does not actually require shapely. It only attempts to load it if it's installed.

Thanks cspotcode, I uninstalled shapely and rebuilt with PyInstaller. Running the executable immediately brought up an error about missing shapely code so I reinstalled shapely. I noticed that the shapely code had changed so I again rebuilt with PyInstaller and reran the executable. Success !

Latest version of shapely solves issue.
