Hi. I have trouble with compiling. Here the log:

It seems you are using Bundler to handle your gems, so you should run bundle exec nanoc compile instead of nanoc compile.

Thanks. May be should to write this in readme or wiki for beginners like me.

I agree the solution to this problem is far from obvious, but it is actually a trivial usage issue with the Bundler and Nanoc gems. I don't think the documentation for my plugin for Nanoc is the right place to address it.
