python - setup.py sdist bdist_wheel

Question

I decided to create a small little module named "NsmPY". Once I had finished the code behind the module (available on GitHub), I got to work trying to upload this new module to PyPi. However, when I ran the necessary command python3 setup.py sdist bdist_wheel, the program spat out an error:

However, in my code there is absolutely no mention of the file or directory 'nsmpy', and even so, the code, setup.py, setup.cfg and all other setup files are all stored in the folder 'nsmpy'.

Furthermore, when I finally did upload this to my account on PyPi (I ran python setup.py sdist) it did work - until I actually decided to install the module with pip install nsmpy, it gave me the following errors:

And yes, I am using the latest modules and latest versions of everything.

from setuptools import setup

setup(
    name="nsmpy",
    version="1.0.0",
    scripts=['nsmpy'])

How does the setup.py file looks like? – Hosmer

honestly, some people just dislike posts because they can; this is an issue stackoverflow needs to sort out. – Dirigible

I downvoted, because in short: the question has not much value to the larger community, it only helps solving one particular issue, that barely anyone else is likely to have (since it's a typo), and if they did they would be unlikely to find this post from a search engine. Downvotes should not be seen as a punishment, often they just mean the question (and their answers) are unlikely to help anyone else. – Hosmer

in which case >90% of all questions on this site would have a vote rating of -20. Also, this was not a typo, and I feel quite strongly that every post has a purpose, thus people with this problem are likely to get help from this post. When you downvote, it makes the post less accessible to those who need it. – Dirigible

Well, another issue with your comment is that stackoverflow is a website for solving issues. – Dirigible

The entire point of a question, no matter how insignificant, is to help whomever asked it, and to help those with a similar issue. This question also was not poorly researched, the reason I asked it was because I had done the research and there were no other instances of this error. Therefore your comment is not valid and will be flagged. – Dirigible

Same root issue, different symptoms: https://mcmap.net/q/1916184/-pip-install-from-git-repository-errors-due-to-wrong-quotes – Hosmer

We should not down-vote a question based on whether there is a value for it or not. SO is often a place where we can find even the most niche scenarios. I would, however, down-voted it because it says nothing in the title. SO has a field for tags. – Assembly

Answer 1

The scripts parameter of setuptools.setup function should be a list of filenames. So in your case I believe it should read:

setuptools.setup(
    # ...
    scripts=['nsmpy.py'],
    # ...
)

Also note that the scripts parameter has somewhat fallen out of favor. It is nowadays recommended to use console_scripts entry points instead, for which there is much more up-to-date documentation available.
