Installing mySql GEM on Ubuntu?

Ruby
1

I am running Linx Mint, a version of Ubuntu, and I installed Ruby
and Rails. However, when I try to install the mySql package via. gem,
“gem
install mysql” I get an error message (See below) with no idea how to
fix
the error. I looked on the net (Google), but all suggestions do not
work
with this Linux.

Also, as far as I know, I have all of the correct mySql drivers/headers,
etc.

=================== error message ==================================

Select which gem to install for your platform (i486-linux)

  1. mysql 2.7.3 (mswin32)
  2. mysql 2.7.1 (mswin32)
  3. mysql 2.7 (ruby)
  4. mysql 2.6 (ruby)
  5. mysql 2.5.1 (ruby)
  6. Cancel installation

apt-get install ruby-dev

If that doesn’t help, tell us how did you install ruby (from package
or from source), and whether you have installed build-essential
package (i.e. can you compile anything?)

Try:

sudo apt-get install libmysql-ruby

This will install the distribution’s MySQL library. It works well in
production, I’ve used it many times in both server and development
environments.
