How Do I Fix SSL Errors When Installing Python Packages with pip?

Troubleshooting SSL Errors During Python Package Installation

When attempting to install Python packages using pip, users may encounter an SSL error that resembles the following:

[SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:590) - skipping

Cause of the Error:

This error arises due to a recent TLS deprecation for pip. Python.org sites have discontinued support for TLS versions 1.0 and 1.1.

Solution:

To resolve this issue, upgrade pip using the following steps:

curl https://bootstrap.pypa.io/get-pip.py | python

Note: If you are using pip within a virtual environment in PyCharm, follow these additional steps:

1. Open a shell and activate the virtual environment.
2. Run the pip upgrade command provided above.
3. Restart PyCharm and verify the updated Python interpreter in the preferences settings.

Additional Notes:

• Upgrading pip through pip itself (e.g., pip install --upgrade pip) will not be effective.
• Python.org has announced the completion of TLS rollbacks, meaning TLSv1.0 and TLSv1.1 are now disabled.
