Pip Package Installation Proxy Configuration

Problem

Pip direct installs were very slow in a colo-hosted environment (Cogent in Anaheim).

Solution

For pip users

Run pip with proxy settings using the --proxy flag:

pip install --proxy http://10.0.10.10:8080 --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org <package_name>

For UV users

Set environment variables before running commands:

export ALL_PROXY=http://123.123.123.123:8080

Also applicable: HTTP_PROXY, HTTPS_PROXY

Notes

• Proxy configuration runs on a Windows machine
• MITMproxy was used as the local proxy server
• Multiple trusted-host flags are needed for various PyPI endpoints
