I recently upgraded mysql on my machine. As a result I'm attempting to update my mysql2 gem accordingly. In the process of doing that, I run "bundle install", and for some reason all of the gems in my Gemfile are getting installed in a ./mysql2 directory??
ruby-1.9.2-p180 [dev]:project.git$ bundle install

Your bundle is complete! It was installed into ./mysql2
For some reason, also my .bundle dir contains a config file that indicates the BUNDLE_PATH is mysql2? I don't know where this came from or how it got there...

I've been spinning my wheels on this for some time. Thanks ahead of time for any ideas or thoughts about how to proceed. (Also, this is the second time that I've bundle installed into a mysql2 dir, so I've decided to stop now before I dig a deeper hole)
It's actually deprecated behavior that I had a problem with a couple weeks ago. It's likely you ran the command bundle install mysql, which actually runs bundle install --path mysql and permanently sets its install directory to ./mysql2 (as little as that makes sense). The easiest way to fix this from happening is by running bundle install --system, and that should restore your default install directory. Next time if you want to upgrade a single gem, use the command bundle update mysql.
I'm not sure why it's installing all to a mysql2 folder, but to get it back to how it should be run this: bundle install --path vendor
You should then be able to safely delete the mysql2 folder and your gems will be where they should be. Hopefully somebody else will be able to explain why it installed into that other folder.
