How to fix ERROR: Could not find a version that satisfies the requirement re (from versions: none)

ERROR: Could not find a version that satisfies the requirement re (from versions: none)
ERROR: No matching distribution found for re

This error can happen for many reasons. Here are the most common ones:

1. Installing from requirements.txt file without adding the -r option.
2. You mistyped the package name (not found in PyPI).
3. The package doesn’t support your operating system.
4. Your pip is outdated.
5. Your Python version is not supported.

PyPI · The Python Package Index

My suggestion is that you can search you targeted package in the foregoing website to identify its existence.

The reason why I encouter the problem? => Since I can't find 're' in PyPI, then I find re is in the Python Standard Library

AM I STUPID? emem...

But I can list some possibilities for you to solve you unique problem.
