Problem: The newly installed annaconda under win10 has no pip3 command.
Solution:
First move to the folder Scripts under anaconda, enter under cmd:
cd C:\Users\10942\Anaconda3\Scripts
Then execute the following command:
easy_install.exe pip
It will be fine after that, because I chose to add the path when I installed anaconda, so I don’t need to add the path at this time, if I don’t add it, I have to add it manually.
