pycharm configuration imutils package

Supplement the pits encountered in the configuration two days ago, for fear of stepping on them in the future

Environment version:

python3.6.4

pycharm community edition

Still don't give up and try to click first: File-Settings-python interpreter-click the "+" sign, search for imutils, and try to install it, but it is still unsuccessful.

Go back to the python terminal

enter:

pip install imutils -i http://pypi.douban.com/simple/imutils/ --trusted-host pypi.douban.com

unsuccessful,

Try another mirror image:

pip install imutils -i https://pypi.mirrors.ustc.edu.cn/simple/ --trusted-host pypi.mirrors.ustc.edu.cn

Still unsuccessful.

Add python -m before pip 

python -m pip install imutils -i http://pypi.douban.com/simple/imutils/ --trusted-host pypi.douban.com

Still unsuccessful.

Then directly:

python -m pip install imutils

In the end, the installation was successful (no ladders, no references to mirror images.) Comparing Buddha, I don’t understand.
