This might sound kind of dumb but I just installed showoff, and then did
$ mkdir myNewPresentation
$ cd myNewPresentation
$ showoff create
and instead of a message saying: usage: showoff create <project name> it just did nothing, and it was not immediately obvious to me why.
usage: showoff create <project name>
Seems to be a bug in GLI. Looking into it…
bumping version of GLI to fix #100
Fixed in GLI 1.3.2 and pull request to update the dependency in #101.
You can avoid this anywhere you have showoff already installed by gem install gli and showoff should use the latest version
gem install gli
