Cannot install mysql2 gem

I'm unable to install the mysql2 gem in my Windows7 x64 system. I tried using both the 32-bit and 64-bit versions of MySQL server but none got me any further. I installed Ruby 1.8, the development kit and and the Rails platform. I even installed minGW to allow C++/C compilation of things. MySQL Server was installed in the default location. When running the command: C:\Users\Arne>gem install mysql2 -- --with-mysql-include="C:\Program Files (x86)\MySQL\MySQL Server 5.1\include" --with-mysql-lib="C:\Program Files (x86)\MySQL\MySQL Server 5.1\lib\" I receive the following output from the console:

Gem::LoadError Specified 'mysql2' for database adapter, but the gem is not loaded. Add `gem 'mysql2'` to your Gemfile This error occurred while loading the following files: active_record/base This is the error I get on running rails server. The mysql2 gem has been added to the Gemfile as well. I've done bundle install , and tried restarting the server but still get the error. Hassan Azimi If you have this error when upgrading to rails 4.2.4 (also with rails 4.1.5) try using this version of mysql2: gem 'mysql2', '~> 0.3.18' Apparently mysql2 isn't still compatible with newer version of rails

Creating tables and problems with primary key in Rails

问题 When I try to run the following code in Rails using Mysql2 as database manager: rake db:migrate I obtain the following error: rake aborted! "Mysql2::Error: All parts of a PRIMARY KEY must be NOT NULL:" Why do I get this error, if the primary key in a table by default is NOT "null"?

The command rails server throws this error.

I figured out what is the problem but I don't know how to solve it. The problem is that there is no any 2.0/ directory in the mysql2-0.3.11-x86-mingw32 gem. This is the gem that rails installs as its dependency from Gemfile : GEM remote: https://rubygems.org/ specs: ... many gems here mysql2 (0.3.11-x86-mingw32) ... many gems here DEPENDENCIES .
