The executable developed via pyinstaller on Pyomo 6.7.3 does not work properly and errors out on execution.
Steps to reproduce the issue
Ran a pyomo 6.7.1 model and tried to build an executable with .spec file (iteratively adding the missing hidden imports). This was successful and the executable worked as expected. However, when upgrading to 6.7.3 on the same project the executable does not work as expected and throws error.
Error Message
When running executable developed with 6.7.3:
File "", line 1360, in _find_and_load
File "", line 1331, in _find_and_load_unlocked
File "", line 921, in _load_unlocked
File "", line 813, in module_from_spec
File "pyomo\common\dependencies.py", line 468, in create_module
AttributeError: 'NoneType' object has no attribute 'create_module'
[10928] Failed to execute script 'main' due to unhandled exception!
Information on your system
Pyomo version: 6.7.1 and 6.7.3
Python version: 3.12
Operating system: Windows 11
How Pyomo was installed (PyPI, conda, source): PyPI
Solver (if applicable): Highs
Additional information
Reverting as on now to 6.7.1 for executable developments, however would like this to work on 6.7.3 as well.
Tested on two different PCs to ensure this is replicable and the same issue persisted with 6.7.3 (while 6.7.1 worked fine) with PyInstaller.
