How to fix ERROR: Could not find a version that satisfies the requirement package Connection to pypi.org timed out in Python

PythonINTERMEDIATEMEDIUM

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.

What this error means

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.

Typical symptoms

pip install fails with version constraint error
Works with different Python versions but not current one
Newer packages available but still get error
Requirements.txt installation fails on specific constraint
Local environment differs from CI/CD pipeline

Common causes

Version constraint too restrictive (no matching versions exist)
Package requires different Python version than installed
Package is archived or removed from PyPI
Using outdated requirements.txt with old version pins
Typo in version specifier syntax
Custom package index missing the required version
Platform-specific wheels not available

How to fix "ERROR: Could not find a version that satisfies the requirement package Connection to pypi.org timed out"

1Check available versions on PyPI

Visit https://pypi.org/project/package-name/ to see all available versions.

2Relax version constraints

Try installing without version constraint first:

bash

pip install package-name

3Verify Python version compatibility

Check that your Python version matches package requirements:

bash

python --version

4Update pip, setuptools, and wheel

Outdated tools can cause version resolution issues:

bash

pip install --upgrade pip setuptools wheel

Advanced notes

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.
