PyPI: Problems uploading a module

Question

I am trying to upload a python module to PyPI using setuptools and twine. My module can be seen at https://pypi.org/project/mousecontroller/. If you try installing the module using pip install mousecontroller, you will encounter an error:

Collecting mousecontroller

note: This is an issue with the package mentioned above, not pip.
hint: See above for output from the failure.

I have done some research on this problem and still have not found anything relevant to me or how to fix this. Here is my setup.py file:

from setuptools import setup, find_packages

setup(
    name='mousecontroller',
    version='1.0.2',
    author='(my name)',
    author_email='(my e-mail)',
    packages=find_packages(),
    url='https://pypi.org/project/mousecontroller/',
    license='LICENSE',
    description='A python package to easily control the mouse in realistic and fluent ways.',
    long_description=open('README.md', 'r').read(),
    long_description_content_type="text/markdown",
    scripts='mousecontroller.py',
    install_requires=['pypiwin32', 'keyboard'],
    classifiers=[
        "Programming Language :: Python :: 3",
        "License :: OSI Approved :: MIT License",
        "Operating System :: OS Independent",
    ],
)

note: I have edited the code and log to protect some of my personal information.

Answer 1

Your script= line is not correct, see the docs:

The scripts option simply is a list of files

You only provided your script as a string, which is split into individual characters when treated as a list. That is why the error message says that C:\Users\me\AppData\Local\Temp\pip-install-60u406eb\mousecontroller_e9ecf1693b5a49f6aa898bb92d39281a\m is not found.

Fix by using squared brackets:

scripts=['mousecontroller.py']

Side Note

mousecontroller.py

is not in the .tar.gz that is available on PyPi. Might be due to the same reason.
