解决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
