I'm having trouble getting started on the ActiveRecords Basics lesson. I'm getting this error when I run bundle for the active records project. I'm not sure how to configure the mysql2 gem. Any suggestions?

Treehouse Guest TeacherHey Zach Hodder what operating system are you using -- are you on a Mac, Windows, or linux computer? Can you try doing the following also and paste the output here:
gem install mysql2

24,138 PointsHi Jason,
Thanks for reaching out. I'm on a Mac running os x 10.9.3. Here's the output after I try to install the gem:

Treehouse Guest TeacherHey Zach Holdren do you have mysql installed?
Formstack Support
24,138 PointsYep. This is what I get when I check the version.
/Applications/MAMP/Library/bin/mysql Ver 14.14 Distrib 5.5.25, for osx10.6 (i386) using EditLine wrapper
Formstack Support
24,138 PointsI did receive this output: -bash: type: mysql: not found
when I tried looking for the location: type -a mysql
Jason Seifer
Treehouse Guest TeacherI think MAMP is going to be the issue here. Try following along with these instructions and see if that helps.

24,138 PointsHi Jason,
It looks like this is the solution. However, I'm running into (no such file or directory) when I try to run step 11. Any suggestions?
