Error while trying to build based on the readme

[fnrizzi]

hi!

I am getting an error when I do the steps in this:
https://github.com/mosra/magnum-website/blob/master/README.rst

Here is what I do:

git clone --recursive git@github.com:mosra/magnum-website.git
pelican -Dlr

and I have installed pelican Pyphen Pillow matplotlib.

I get:

I also had to add the m.css/plugins to my pythonpath to get to this point.
Am I missing something?
Thanks for the help!

Hi!

Unfortunately m.css plugins don't work with the recently released Pelican 4.5 -- there were some breaking changes in Pelican and I still need to investigate what's going on and how to fix it. I'm very busy these days so I can't promise when that will be, tho.

Everything should work if you downgrade to Pelican 4.2 ;)

Hi!
Ok, sounds good, I will try that.
No problem!

P.s. your work is awesome :)
