Ask HN: Installing Mysql2 gem ruby on rails problem

[maze]

Hi, I don't know if I should ask this type of question here or not.

I am trying to install the mysql2 gem file for ruby on rails development, but when I enter "gem install mysql2" in the terminal, this comes up:

arks-MacBook-Pro:~ Mark$ gem install mysql2 Building native extensions. This could take a while... ERROR: Error installing mysql2: ERROR: Failed to build gem native extension.

Gem files will remain installed in /Users/useruser/.rvm/gems/ruby-1.9.2-p136/gems/mysql2-0.2.6 for inspection. Results logged to /Users/useruser/.rvm/gems/ruby-1.9.2-p136/gems/mysql2-0.2.6/ext/mysql2/gem_make.out

Can anyone help please?

SO is usually really good for stuff like this. If it doesnt work in a few more hours, also try the other SE sites.

I have finally managed to fix it! :)

View the question http://stackoverflow.com/questions/5409761/installing-mysql2... and I'm sure you will manage to install it too. I installed "Homebrew" the installed mysql then the mysql2 gem..

Just follow the answer with from ALoR
