Question

I have go following error while executing Jekyll serve --watch

WARN: Unresolved specs during Gem::Specification.reset:
      rb-fsevent (>= 0.9.4, ~> 0.9)

Please report a bug if this causes problems.

If you haven't changed sources, that means the author of minima (1.0.1) has removed it. You'll need to update your bundle to a different version of minima (1.0.1) that hasn't been removed in order to install. (Bundler::GemNotFound)
