I then used rbenv to install the current stable version of ruby (2.2.2 currently).
The bundle command wasn’t found. I quickly realized that I don’t have any gem bin directories in my path and immediately lamented that I have no way to know even where they were with rbenv. I did manage to track the bundle binary down but it was in a very convoluted place. Not ideal for just running off the cuff. After a little head scratching and google searches I figured out the solution. I need to regenerate pathes each time I do a gem install.
After doing this the bundle command was accessable as a normal binary. Doing a rehash was further re-enforced after installing jekyll. Once again it wasn’t in the path, but a quick rehash did the trick.
I need to remember that from now on if I install a gem with a binary I need to rehash.
