Rails 2.3.5-安装mysql时出错：错误：无法构建gem本机扩展。

Question

I tried with gem install mysql and gem list, so I was able to see mysql gem in that list, but when I restarted the server it gives me following error

The bundled mysql.rb driver has been removed from Rails 2.2. Please install the mysql gem and try again: gem install mysql. /Users/.rvm/rubies/ruby-1.8.7-p357/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:29:in `gem_original_require': no such file to load -- mysql (MissingSourceFile)

I then tried gem install mysql2 It installs mysql but gives the same error when I start the server.. Please help! Thanks in advance

Answer 1

You have to specify what gems your project includes. In Rails 2.2, you did this in the environment config files. Change this line in your environment.rb :

  config.gem 'mysql'

To this:

  config.gem 'mysql2'
