启动rails服务器时出现以下错误:
$ rails server
/Users/ssmith/.rvm/gems/ruby-1.9.2-p0/gems/mysql2-0.2.6/lib/mysql2.rb:7:in `require': dlopen(/Users/ssmith/.rvm/gems/ruby-1.9.2-p0/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle, 9): Library not loaded: libmysqlclient.16.dylib (LoadError)

Reason: image not found - /Users/ssmith/.rvm/gems/ruby-1.9.2-p0/gems/mysql2-

在rvm使用ruby-1.9.2-p0命令后,我用以下命令安装了mysql2:
$ gem install mysql2 -- --with-mysql-dir=/usr/local/mysql --with-mysql-config=/usr/local/mysql/bin/mysql_config

我的Gemfile以及database.yml文件中都有mysql2,bundle install就可以了
$ bundle show mysql2

我理解rails服务器错误是由于它不知道OSX上的mysql_config位置,但是在gem …
要使用MySQL创建Rails应用程序,我执行以下操作:
rails new application -database=mysql
但这不起作用,而是它给了我的SQLite.我不想要SQLite,我想要MySQL.
我怎么解决这个问题？
