I have a gem installed system-wide called
scrapers that has a binary
rubytapas. It will run nearly everywhere except within a
directory that contains a Gemfile.
It can be a completely empty directory otherwise, and the Gemfile can
be empty. It still fails by getting confused about finding
The gist https://gist.github.com/tamouse/9822711 shows what is
happening, I think.
The gist of the gist is:
rubytapas all # Download all rubytapas episodes
rubytapas download # Downloads the listed episode’s files
into a new directory with the episode tag in the given directory
rubytapas help [COMMAND] # Describe available commands or one
$ touch Gemfile
require': cannot load such file -- thor (LoadError) from /opt/rubies/ruby-2.0.0-p353/bin/rubytapas:4:in’
