I have been trying to install a custom module created for GNU Health on openSUSE, however in the documentations a directory is mentioned that is not available when installing via zypper. The documentation on openSUSE does not mention a way to install custom modules either.I have created a test module by changing a core module downloaded from source files, and tried to:- Install it via the setup.py- Copy it to /usr/lib/python3.6/site-packages/trytond/modules- Copy a module from /usr/lib/python3.6/site-packages/trytond/modules and edit it, then place it back in the directory.However, it never shows on the modules menu to be marked for activation from the GNU Health client.
