I first discovered this when I downloaded a gem and attempted to build it. It builds fine with no errors. I do a gem install and it says it installs properly. I attempted to require it using irb and it tells me not found. I did a gem list and it shows up. Finally I looked in the gem folder and there is an entry for the gem there, however looking in the gem folder it is empty.
I attempted to install an online gem azimutto and it is also an empty folder.
I am at a loss as to why installing a downloaded git repository of a gem does not install properly.
I am using RVM and have re-installed it.
