Expected results

No error

[Grazfather]

Do you ALSO have gef installed?

[aliencaocao]

Yes, does that conflict?

[Grazfather]

Both should be installed. I think perhaps you need to update GEF as well. Please try that.

[aliencaocao]

My gef is latest dev version

[maple3142]

I am getting this error too, but it only happens on ropper.py. This is due to a common Python error of naming a file with the same name as other packages ropper (reference).

Renaming ropper.py to ropper_.py helps.

[SuperStormer]

Also resolved by pip install ropper.
