How Can I Fix A Py2app Error When Building With Py2app

Trying to build a simple wxpython app using py2app and using pyenv. I created a virtual environment from whence I run the application and build with py2app. It fails during build

Solution 1:

Ok, I found out what the problem was. When I pyenv installed the 3.8.5 version of python, I had not set this environment variable.

PYTHON_CONFIGURE_OPTS=--enable-framework

So once I uninstalled it and re-installed with the above option py2app started working correctly again. Mystery solved.
