'pip install' Fails for Every Package: "Could Not Find a Version That Satisfies the Requirement"
This error, "Could not find a version that satisfies the requirement," indicates difficulties with installing packages using 'pip install.' To resolve this issue, consider the following steps:
Upgrading pip
Use the following command to upgrade pip:
curl https://bootstrap.pypa.io/get-pip.py | python
Note that you may need to use 'sudo python' if not in a virtual environment.
TLS Version Support
Older versions of macOS (10.12 Sierra or earlier) no longer support TLS versions 1.0 and 1.1. This means pip will fail to connect to the Python Package Index (PyPI) unless upgraded using the aforementioned command.
Additional Upgrade
After upgrading pip, also upgrade setuptools:
pip install --upgrade setuptools
By following these steps, you can resolve 'pip install' installation issues and ensure compatibility with the latest TLS security standards.
