pip cannot locate a package version matching your specified requirements. This usually happens with overly strict version constraints or packages not supporting your Python version.
Fixes ERROR: Could not find a version that satisfies the requirement package Connection to pypi.org timed out

pip searches for package versions matching your version specification. When none are found, this error occurs because your constraint is too strict, the package does not support your Python version, or the package has been removed from PyPI.
Visit https://pypi.org/project/package-name/ to see all available versions.
Try installing without version constraint first:
pip install package-nameCheck that your Python version matches package requirements:
python --versionOutdated tools can cause version resolution issues:
pip install --upgrade pip setuptools wheelUse ~= operator for sensible version constraints:
pip install "package-name~=1.4.5"For complex dependency resolution, use pip-tools or Poetry. These tools help identify compatible versions. Check the changelog to understand why an older version was required.
