我在使用 ActiveScaffold 和 Rails 4 时遇到了一个非常奇怪的错误。我创建了一个全新的项目，运行“rake db:create”和“bundle install”，然后将 gem active_scaffold 添加到我的 gem 文件中并再次运行“bundle install” . 此时一切正常。

然后，当我尝试输入时：

rails g active_scaffold Test test:string

我得到：

/Users/rgrzesik/.rvm/gems/ruby-2.0.0-p247/gems/active_scaffold-3.2.20/lib/active_scaffold.rb:2:in `<top (required)>': This version of ActiveScaffold requires Rails 3.1 or higher.  Please use an earlier version. (RuntimeError)

是什么赋予了？我正在运行 Rails 4，它远远超出了 Rails 3.1。有任何想法吗？

看起来还没有发布版本包含该 Rails 4 支持。您可以随时使用来自 github 的当前版本来试试运气：gem 'active_scaffold', github: 'activescaffold/active_scaffold', branch: 'master'

然后，您可以密切关注 3.4.0 的发布。与此同时，你会不断地从主分支获得最新的东西（可能是坏的，或者至少不是“保证满意”）。
