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

I am using Python 3.6. When I try to install “modules” using pip3, I face this issue:

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

For Windows 10
if you want use pip in normal cmd, not only in Anaconda prompt. you need add 3 environment paths.
like the followings:

D:\Anaconda3 
D:\Anaconda3\Scripts
D:\Anaconda3\Library\bin 

most people only add D:\Anaconda3\Scripts
