Why do I get an error when downloading a project with pypi?

Question

Python

Deployed my project on pypi (first time, newbie):

The project's long description is valid RST.

As you can see, everything goes well, and 200 OK is displayed.
But when I then try to download the project from PIP3, I see the following error:

What could be wrong?

Answer 1

setup.py tries to take description from README.txt, while README.rst is loaded in the project Correct
the file name.
