軌生成NoMethodError

Question

我有一些麻煩與我的Rails環境破 - 就像運行一個命令：

$ rails generate scaffold_controller model_name 

結果如下跟蹤：

/Users/me/.rvm/gems/ruby-1.9.3-p392@myproject/gems/railties-3.2.13/lib/rails/generators/generated_attribute.rb:13:in `parse': undefined method `split' for :clear:Symbol (NoMethodError) 
    from /Users/me/.rvm/gems/ruby-1.9.3-p392@myproject/gems/railties-3.2.13/lib/rails/generators/named_base.rb:161:in `block in parse_attributes!' 
    from /Users/me/.rvm/gems/ruby-1.9.3-p392@myproject/gems/railties-3.2.13/lib/rails/generators/named_base.rb:160:in `map' 
    from /Users/me/.rvm/gems/ruby-1.9.3-p392@myproject/gems/railties-3.2.13/lib/rails/generators/named_base.rb:160:in `parse_attributes!'

    from /Users/me/.rvm/gems/ruby-1.9.3-p392@myproject/gems/thor-0.18.1/lib/thor/group.rb:227:in `new'

    from /Users/me/.rvm/gems/ruby-1.9.3-p392@myproject/gems/railties-3.2.13/lib/rails/generators.rb:171:in `invoke' 
    from /Users/me/.rvm/gems/ruby-1.9.3-p392@myproject/gems/railties-3.2.13/lib/rails/commands/generate.rb:12:in `<top (required)>' 
    from /Users/me/.rvm/gems/ruby-1.9.3-p392@myproject/gems/activesupport-3.2.13/lib/active_support/dependencies.rb:251:in `require' 
    from /Users/me/.rvm/gems/ruby-1.9.3-p392@myproject/gems/activesupport-3.2.13/lib/active_support/dependencies.rb:251:in `block in require' 
    from /Users/me/.rvm/gems/ruby-1.9.3-p392@myproject/gems/activesupport-3.2.13/lib/active_support/dependencies.rb:236:in `load_dependency' 
    from /Users/me/.rvm/gems/ruby-1.9.3-p392@myproject/gems/activesupport-3.2.13/lib/active_support/dependencies.rb:251:in `require' 
    from /Users/me/.rvm/gems/ruby-1.9.3-p392@myproject/gems/railties-3.2.13/lib/rails/commands.rb:29:in `<top (required)>' 
    from script/rails:6:in `require' 
    from script/rails:6:in `<main>' 

如無物的痕跡似乎即使是來自我的具體項目，我對於可能發生的事情有點難以理解。正如你所看到的，我在運行rvm的ruby 1.9.3上運行rails 3.2.13。

任何想法？

Answer 1

我有同樣的問題。事實證明，我在我的代碼中的某處存在以下行。

include Term::ANSIColor 

此代碼是彩色術語輸出所必需的。但是，當您需要生成或銷燬腳手架時，暫時將其評論出來是很好的做法。方法或符號'明確'與其他寶石衝突。所以這可能會修復rake：erd。
