rails 3 not working with windows 7

ruby 1.8.7 g开发者_Python百科em 1.3.7 rails 3.0.0, 3.0.0.rc

when i write rails -v error message come

Could not find gem 'mysql2 <>=0, runtime>' in any of the gem sources. Try running 'bundle install'.

when I run bundle install then also it cann't install mysql2

please help me.

The mysql2 gem does not currently support Windows (although I hear they are working on it). Just use the old mysql gem for now.

To be specific:

1. Put this line in your Gemfile:

   gem 'mysql', '2.8.1'

2. Run bundle install

3. Make sure you use adapter: mysql and not adapter: mysql2 in your database.yml.

This is how my system is currently set up, and it works fine with Rails 3.0.0.

This error can be handled now. No need to change mysql2 to mysql in Gemfile and database.yml. You can install mysql2 gem on windows by following the steps given in post - http://rorguide.blogspot.com/2011/03/installing-mysql2-gem-on-ruby-192-and.html
