.Spec file can build on my computer but cannot build on another computer

[isisgonzalez183]

Hello all,
So I created a spec file to build an executable. The executable I built can run on any computer (without python and the repo), however when I shared the .spec file for a colleague to build with (same repo and we are both using Visual Studios) he cannot build a working executable (numerous import errors). So far I have looked into sys.path and have modified the spec file to include each missing module by appending to datas, but there are a lot of modules missing so it is a cumbersome process and I do not need to do any of this on my computer.
Any ideas as to what else to check?

He's probably mixing up Python environments so that pyinstaller and his packages are in different environments. Get him to use python -m for pip and PyInstaller.

python -m pip install pyinstaller your dependencies here

# Check your code actually runs under this Python environment when invoked from cmd.
python your-code.py

# Do the build - note PyInstaller is case-sensitive here 
python -m PyInstaller your-spec-file.spec

Thank you so much it worked like a charm! Note for anyone else reading this thread: He also uninstalled all packages from his machine and deleted the working virtual environment. He then reinstalled all packages and the virtual environment with the python -m pip install flag.
