Have you tried to see if it was successful? Maybe mGear is installed already.
If that “Installation Complete” message ran, then it seems like the drag_n-drop_install.py script ran successfully. That’s the last line in that function.
The error might be from del myTempEDPF
which is… what? Maya’s wrapper for dragging Python files?
(Just guessing. I install mGear through Maya.env.)
Try restarting Maya and maybe mGear is installed.
- See if you get any mGear errors when you start Maya.
- Check if it shows up in the menu.
- Try running
import mgear
and see if you get an error. (If you don’t get an error, then it is installed, but you are still experiencing the missing menu problem.)
