I tried to run miniedit.py after I have mininet installed, unfortunately, I got the error:
ImportError: cannot import name customClass.
Checked the py file: ~/mininet/mininet/util.py and miniedity.py, find nothing is wrong, search on the Internet, got no clue.
Suddenly I found the version is not the version I wanted to install (I forgot to take a screenshot, the version should be 2.2.2daily something).
I guess there must be something wrong with the latest version, or there is something conflict with my previous version (mininet 2.0.0 was installed on the PC before).
Resolution:
Follow the official guide to remove all mininet by following Option3, and install it again by following Option2, it works then:
