在运行现有Rails App的新本地计算机上启动Rails服务器时出错

Question

当我跑步时

./script/server

我收到以下错误消息，我似乎无法找到如何解决问题。该文件夹位于我的桌面上，是在运行MacOSX 10.8.3的新计算机上从SVN存储库结账。

/Users/martin/Desktop/[FOLDER NAME]/config/boot.rb:89:in `load_rubygems': undefined method `set_paths' for Gem:Module (NoMethodError)
from /Users/martin/Desktop/[FOLDER NAME]/config/boot.rb:52:in `load_initializer'
from /Users/martin/Desktop/[FOLDER NAME]/config/boot.rb:39:in `run'
from /Users/martin/Desktop/[FOLDER NAME]/config/boot.rb:11:in `boot!'

from ./script/server:2:in `<main>'

有没有人对如何修复/排除故障有任何想法？

如果我运行which -a ruby，我会：

/Users/martin/.rbenv/shims/ruby
/Users/martin/.rbenv/shims/ruby
/Users/martin/.rbenv/shims/ruby
/Users/martin/.rbenv/shims/ruby
/Users/martin/.rbenv/shims/ruby
/usr/bin/ruby


rails -v

Rails 4.0.0

ruby -v

ruby 2.0.0p0 (2013-02-24 revision 39474) [x86_64-darwin12.3.0]

运行script/server会出现不同的错误
