gtk+3 does not work.
Hello, I am trying to run gtk+3 on my mac Mojave but it did not work. I tried to reinstall it and it always showed error that gtk+3 was installed. However, when I tried to run Hello.py, no new window showed. Instead, the results was showed on the terminal. Can you tell me how to run it. I need gtk for another code (p4vasp).
brew install pygobject3 --with-python@2 gtk+3
Warning: pygobject3 3.30.4 is already installed and up-to-date
To reinstall 3.30.4, run `brew reinstall pygobject3`
Error: gtk+3 3.24.2 is already installed
To upgrade to 3.24.2_1, run `brew upgrade gtk+3`
python2 duc0.py Hello!
