“ssl module in Python is not available” when installing package with pip3

Question

I\'ve install Python 3.4 and Python 3.6 on my local machine successfully, but am unable to install packages with pip3.

When I execute pip3 install

Answer 1

In my case with using Mac, I deleted /Applications/Python 3.7. because I already had Python3.7 by brew install python3 .

But it was a trigger of the message

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

What I did in my situation

1. I downloaded macOS 64-bit installer again, and installed.
2. Double click /Applications/Python3.6/Install Certificates.command and /Applications/Python3.6/Update Shell Profile.command.
3. Reboot mac
4. And I am not sure but possibly contributed to succeed is pip.conf. See pip install fails.
