Question

我刚在Mac OSX 10.7.4上使用Rails安装程序安装了rails env。

我使用“rails new”命令创建一个项目。

当我尝试运行“rails server”命令时，我收到此消息：

/usr/local/rvm/gems/ruby-1.9.3-p194/gems/rails-2.3.14/lib/rails_generator/options.rb:32:in `default_options': undefined method `write_inheritable_attribute' for Rails::Generator::Base:Class (NoMethodError)

from /usr/local/rvm/gems/ruby-1.9.3-p194/bin/rails:23:in `<main>'

当我运行$ ruby -v和$ gem -v时，我分别得到“ruby 1.9.3p194”和“1.8.24”。我在这里错过了什么？如何让这台服务器运行？

Answer 1

看起来你正试图在Rails 2.3中使用Rails 3.x命令。在3.0版之前，您必须使用服务器脚本。

从您的应用程序目录中运行：

./script/server

Answer 2

将rails安装为gem gem install rails。当您使用rvm时，此处显示的文件夹路径显示rails 2.3.4，而您尝试运行rails server。检查/更改gem文件中的rails版本，然后执行bundle install。
