TypeError: expected str, bytes or os.PathLike object, not NoneType

I made a van.py file next to my flask app. These are the settings specified:

import pyvan
OPTIONS = {"main_file_name": "flask_app.py",
            "show_console": False,
            "use_pipreqs": True,
            "install_only_these_modules": [],
            "exclude_modules":[],
            "include_modules":[],
            "path_to_get_pip_and_python_embeded_zip": ""
            }

pyvan.build(OPTIONS)

Though I get this error (which I'm not sure what it means, I think it might have to do with the last parameter of path to get pip. I'm running MacOS Mojave, Python 3.7.

I tried finding those files online and adding them manually, I added get-pip.py from: https://bootstrap.pypa.io/get-pip.py
And I added Python 3.7.4: python-3.7.4-embed-amd64.zip
I placed both in a folder called 'pathtoe' and I set that folder to the parameter path_to_get_pip_and_python_embeded_zip

I ran, and now I have this new error. Does pyvan only work with windows?

pyvan is mainly for windows.. (.exe is for windows on mac executables end with .app)
Linux and mac have already python installed and they don't have a python embeded version available to download.

If you want you can make a pull request and add the bellow requirements needed to run on linux/mac.

• detect if os is windows if not skip the python embeded step and
• just make a batch file that will start the script using the already installed python on linux/mac
• also when started it should install the modules needed

The pyvan source file is not that big (about 300 lines) no complicated things going there.
