When I type yesod devel I get the following error:
ERROR: file devel.hs not found
How do I fix this?
I'm on Ubuntu 12.04.1 LTS, my ghc version is 7.4.1 and my yesod version is 0.10.2.1
It sounds like you have not setup the Yesod scaffolding yet. Run 'yesod init' first, then cd into the created directory and try 'yesod devel'.
