Answer 1

which OS are you using?

anyway if you are using ubuntu, from this https://github.com/brianmario/mysql2/issues/8 run:

sudo apt-get install mysql-client libmysqlclient-dev

---

Otherwise for Mac users,(use brew to install) check this http://mxcl.github.com/homebrew/, or run:

brew install mysql

then

sudo gem install mysql2

---

and for windows users check the link below for a solution. Error installing mysql2: Failed to build gem native extension

I would recommend to use the normal command prompt.
