[Error]: No module named charm

[redshark314]

I installed charm by following this link
https://zhuanlan.zhihu.com/p/447934026

The installation works and the charm package is installed in /usr/local/src/charm-dev
When I use python3 -> import charm in that path, it works.

But when I use it anywhere else, it gives the error. No module named 'charm'

My question is, why is it so? Also, how can I make it work from anywhere in the system?

Since there is no more information, I can only guess that the python you are using and the one you have installed are not the same.
