Package installation: Timeout due to corporate proxy

Problem

When attempting to import various Python packages installation fails with a timeout error caused by a corporate proxy.

Cause

Pip relies on environment variables and/or pip.ini configuration for proxy settings during package installation. While PyCharm's "No proxy" setting allows "Check Connection" to work, the actual installation process performed by pip is affected by the corporate proxy, resulting in connection timeout errors.

Resolution

Step 1: Verify the issue outside PyCharm

Use the system terminal to attempt the installation and confirm the issue is proxy-related:

"C:\Users\<User>\AppData\Local\Programs\Python\Python314\python.exe" -m pip install -vvv  <package_name>

If the timeout error persists, the issue is independent of PyCharm.

Step 2: Check pip.ini configuration

Verify if proxy settings are defined in pip.ini files:

• User-level pip.ini: C:\Users\<User>\AppData\Roaming\pip\pip.ini
• System-level pip.ini: C:\ProgramData\pip\pip.ini

Refer to pip's official documentation for detailed guidance on configuring proxies.

Step 3: Update proxy settings or use an alternative solution

If your corporate proxy blocks direct connections, configure the correct proxy credentials in pip.ini or use an alternative approach, such as downloading packages manually and installing them via pip install <package_name>.whl.

For persistent proxy issues, consult your IT department to explore further options.
