Question

<_>使用

安装has_many_polymorphs后立即执行

ruby script/plugin install git://github.com/fauna/has_many_polymorphs.git

每当我尝试执行像script / generate或script / server

这样的smth时，我就会开始出现以下错误

Answer 1

尝试从

更改autoload.rb中的第41行

  open(filename, :encoding=>"utf-8") do |file|

到

 open filename do |file|

至少应用程序现在为我启动了。
