Rails错误：`在< top（必需）>中拯救：未初始化的常量Bundler（NameError） [英] Rails error: `rescue in <top (required)>': uninitialized constant Bundler (NameError)

问题描述

今天早些时候，我用我的系统更新了宝石：

  gem update 
  
 
 
 
它更新了一些宝石，但在此之后我无法启动我的Rails服务器，出现此错误：
  /Users/gugguson/rubys/my_rails_app/config/boot.rb:9:in`rescue in< top（required）>'：未初始化的常量Bundler（NameError） from /Users/gugguson/rubys/my_rails_app/config/boot.rb:5:in从< internal：lib / ruby​​gems / custom_require>的<< top（required）>'
：
：29 ：在`require'
 from< internal：lib / ruby​​gems / custom_require>：29：'require'
 from脚本/ rails：5：< main>'
  
如果我使用以下方式创建新应用程序：
  rails new test99 
  
 ...然后进入文件夹并运行rails服务器s我得到这个错误：
 
 $ p $  [〜/ ruby​​s / test99] rails s 
< internal：gem_prelude> ：168：在`load_full_rubygems_lib中rary'：未定义的Gem :: QuickLoader的本地变量或方法`path'：Module（NameError）

有什么想法？

解决方案

正如lebreeze所说，尝试使用更新rubygems gem update - 系统。看起来像是一些问题，并且它们在最新版本中已修复。

Earlier today I updated gems on my system with:

gem update

It updated few gems but after that I can't start my rails server, I get this error:

/Users/gugguson/rubys/my_rails_app/config/boot.rb:9:in `rescue in <top (required)>': uninitialized constant Bundler (NameError)
    from /Users/gugguson/rubys/my_rails_app/config/boot.rb:5:in `<top (required)>'
    from <internal:lib/rubygems/custom_require>:29:in `require'
    from <internal:lib/rubygems/custom_require>:29:in `require'
    from script/rails:5:in `<main>'

If I create a new app with:

rails new test99

... and then go into the folder and run rails server s I get this error:

[~/rubys/test99] rails s

    from <internal:lib/rubygems/custom_require>:29:in `require'

Any ideas?

Thanks, Johann

As lebreeze said, try updating rubygems with gem update --system. Looks like there were some issues and that they were fixed in recent versions.
