I am sorry to bother you guys again… I sincerely tried to fix this problem by myself before asking you some help.
Ii would like to use these 2 extensions :
So I installed them via the plugin manager, and then Glyphs told me I need to install Python.
So I did from the official website.
Now when I open the Glyphs app, a pop-up opens and says : Python installation needs this missing module : « PyObjcC » You can install « pip3 install pyobjc » in the Terminal or using the Python module from the plugin manager.
So I looked for this module in the plugin manager, but I don’t find it, and when I typed « pip3 install pyobjc » in the Terminal, it says « command not found »
Does someone know how to find a solution ?
