Weird… I have the same version you have, and it work find on my computer!
I did revert back to v5.0.2 since this morning. I wonder if that is a difference with the nightly build? So many variables!
Just to confirm, what exactly worked on your computer?
4.0.7 installed into C:\Program Files\KiCad_4.0.7
5.0.2 installed into C:\Program Files\KiCad_5.0.2
nightly (6.0.0-rc1-dev-1455-g4b7ef22ec) installed into C:\Program Files\KiCad_r12070
All of them are working with “import pcbnew”, and sys.path are seem to point to the correct folder that I installed them!
Weirder and weirder!
Just to confirm, you are NOT using the scripting console in PCBNEW right?
Also, what is your Windows version?
Would it be you have a mix-match version of _pcbnew.pyd ? Or more than 1 _pcbnew.pyd in your installation folder?
I try both from pcbnew console, and CMD… They both work!
It seem to me, this may mean the _pcbnew.pyd version are mix match with other DLL install in KiCad folder…
I didn’t find any extra _pcbnew.pyd copies. Also, when I installed v5.0.2, I uninstalled KiCad first and made sure C:/Program Files/KiCad was empty.
That seem weird! I have no more idea for now!
Thank you very much for the ideas and confirmation that it works on your PC though!
Oh, my is Windows 7, x64
