Hi:

I’m not sure what that error means. Does it have more at the bottom,
perhaps with line numbers etc? Please post the entire error, maybe that
will help.

It might be having trouble loading gtksourceview3. Try manually
installing it like so:

gem install gtk3
gem install gtksourceview3

It seems to be complaining about GtkSource which is a part of
gtksourceview3.

I uploaded a new gem, so you can try it too:

gem install visualruby

Let me now if any of this helps.

Best,
Eric
