Bundler will not install mysql2

Question

First of all, I went through dozens of posts here on SO and google, and could not find the answer. I am trying to install mysql2 with bundler and it will not do this.

Powered by Ubuntu 11.04 Natty Server

Here is some background information:

ruby -v ruby 1.8.7 (2012-02-08 patchlevel 358) [x86_64-linux] gem -v 1.8.24 rails -v Rails 3.2.5 $ mysql --version mysql Ver 14.14 Distrib 5.1.62, for debian-linux-gnu (x86_64) using readline 6.2 

I have a gem "mysql2", "~> 0.3.11" in my gemfile

When I execute bundle install , it goes through the process and succeeds ( No errors ), but it does not install mysql2. When I do a bundle show , mysql2 is not specified.

I tried the gazillion recommended here and on the forums and still cannot get mysql2 to install using bundler.

Any ideas?

Thanks.

Answer 1

So, after many attempts, reading and pulling hair, I found out what the problem is, so I send it to those who may encounter the same situation.

The reason the bundler will not install mysql2 is because the stone was inside this platform structure, see below:

 platforms :mri_19, :mingw_19 do group :mysql do gem "mysql2", "0.3.11" end end 

So, all I did was move only the gem "mysql2", "0.3.11" by itself to the top of the Gemfile and run bundle install , and that did it! Mysql2 is now listed in the package list, and the rails application is now running.

Thanks to everyone who tried to help!

For mysql2 you need to install dev files on your server.

try first:

 sudo apt-get install libmysqlclient-dev 

Then first check your GemFile in your RoR root directory. I have this line in my GemFile:

 gem 'mysql2', '0.3.11' 

execute package:

 bundle install 

or try the command from Emily first, then install the package:

 gem install mysql2 -v=0.3.11 bundle install 

I hope this helps
