Rails3服务器和bundler错误:未初始化的常量Bundler(NameError)

Question

我只是安装了rails 3以及它需要的所有gem,但是当我尝试启动服务器时,它会说出启动脚本中的问题.

[rap-kasta@acerAspire testR3]$ script/rails server  
/home/rap-kasta/tmp/testR3/config/boot.rb:7:in `rescue in <top (required)>': uninitialized constant Bundler (NameError)  
        from /home/rap-kasta/tmp/testR3/config/boot.rb:2:in `<top (required)>'  
        from script/rails:9:in `require'  
        from script/rails:9:in `<main>  

所以,我试图重新安装Bundler,安装"pre"-version(但实际上它的版本号低于我安装的版本号 gem install bundler

现在系统中有下一个宝石:

abstract (1.0.0)
actionmailer (3.0.0.beta, 2.3.5, 2.3.4)
actionpack (3.0.0.beta, 2.3.5, 2.3.4)

此外,还有同样的错误与rails console和类似bundle check:

[rap-kasta@acerAspire testR3]$ bundle check
/usr/lib/ruby/gems/1.9.1/gems/bundler-0.9.5/bin/bundle:12:in `rescue in <top (required)>': uninitialized constant Bundler::BundlerError (NameError)
        from /usr/lib/ruby/gems/1.9.1/gems/bundler-0.9.5/bin/bundle:10:in `<top (required)>'
        from /usr/bin/bundle:19:in `load'
        from /usr/bin/bundle:19:in `<main>'

Answer 1

它添加后有效:

gem install bundler

并在添加之后:

gem 'bundler'

在config/boot.rb中的第2行(在require'rubygems'之后)
