Hey all,
When i tried to import a module into scribus on windows, it always said that the module was not installed, even if Environment variables were setup and the module was correctly installed on python itself.
I therefore ran this inside the console in Scribus
import pip
pip.main(['install', '<moduleName>'])
This installs the package for all users for Scribus, after a restart of Scribus you can use it in the console or in your scripts.
I don't know if this is the best way to do it, but it works for me. Hope this helps someone
PS: pip has to be installed i suppose. For me that worked without any troubles
