我在 environment.rb 中添加了一句 config.gem 'tiny_mce',具体如下:

Load the rails application

require File.expand_path('../application', FILE)

Initialize the rails application

MyBlog::Application.initialize! config.gem 'tiny_mce'

一启动服务就出现如下错误:

请问有什么解决方法吗?

rails3 用 gemfile

config.gemfile 'tiny_mce' 这样吗?也是报同样的错误

是在 gemfile 里用 gem 'tiny_mce'
