pip install failing with SSL certificate error

Question

When I try pip install, I get SSL: CERTIFICATE_VERIFY_FAILED error. How can I fix this?

SSL certificate errors can occur due to corporate proxies or outdated certificates. Here are the solutions:
Update pip and certificates
# Update pip
python -m pip install --upgrade pip
# Install/update certificates
pip install --upgrade certifi
Use trusted host (temporary fix)
pip install --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org package-name
Set in pip.conf (permanent fix)
# Create/edit ~/.pip/pip.conf
[global]
trusted-host = pypi.org
               pypi.python.org
               files.pythonhosted.org
