python version coexistence problem
As we all know, different versions of python can coexist, and there is a lot of information on the Internet, so there is not much to say about installation, renaming and pip configuration.
Quoting an article from a blogger: http://blog.csdn.net/autista/article/details/73650943
I ran into some peculiar problems myself. Is the problem between 3.6 and 3.7 version. After I installed 3.7, I installed 3.6 (and added environment variables). But it is not possible to call 3.6 directly from the command line. After checking, the settings in the environment variables are OK. It can be opened from the downloaded interpreter command box of 3.6, but the system does not recognize the path of "python3.6", and it is invalid to open from cmd
If you have friends with the same problem, I hope to discuss together
