`require＆＃39;：无法加载这样的文件 - rack-webconsole（LoadError）

标签： ruby-on-rails ruby-on-rails-3 bundler

我刚刚升级到Yosemite，我在这台本地计算机上运行了一个Rails 3.2.18应用程序。它运行正常（例如rails s工作，rails c工作等等）但是在清理rvm并重新捆绑后，我在运行rails c或rails s时遇到此错误：

/Users/cweilemann/.rvm/gems/ruby-2.1.1@global/gems/bundler-1.6.1/lib/bundler/runtime.rb:76:in `require': cannot load such file -- rack-webconsole (LoadError)
    from /Users/cweilemann/.rvm/gems/ruby-2.1.1@global/gems/bundler-1.6.1/lib/bundler/runtime.rb:76:in `block (2 levels) in require'
    from /Users/cweilemann/.rvm/gems/ruby-2.1.1@global/gems/bundler-1.6.1/lib/bundler/runtime.rb:72:in `each'
    from /Users/cweilemann/.rvm/gems/ruby-2.1.1@global/gems/bundler-1.6.1/lib/bundler/runtime.rb:72:in `block in require'
    from /Users/cweilemann/.rvm/gems/ruby-2.1.1@global/gems/bundler-1.6.1/lib/bundler/runtime.rb:61:in `each'
    from /Users/cweilemann/.rvm/gems/ruby-2.1.1@global/gems/bundler-1.6.1/lib/bundler/runtime.rb:61:in `require'
    from /Users/cweilemann/.rvm/gems/ruby-2.1.1@global/gems/bundler-1.6.1/lib/bundler.rb:132:in `require'
    from /Users/cweilemann/Projects/railsapp/config/application.rb:7:in `<top (required)>'

config / application.rb的第7行是：

Bundler.require(*Rails.groups(:assets => %w(development test)))

在我的Gemfile中，我有：

group :development do
  ...
  gem 'rack-webconsole-pry', :require => 'rack-webconsole'
  ...
end

如果我将gem 'rack-webconsole-pry', :require => 'rack-webconsole'行移到group :development之外，则应用加载就好了。如果我删除了:require => 'rack-webconsole'，该应用就可以正常加载。

这是捆绑问题吗？或者是Rails和优胜美地的问题？

更新

gem env

注意：我出于安全目的编辑了bundle env列表，因为这是一个生产应用程序。

当我这样做时：bundle show --paths rack-webconsole-pry

我明白了：

Could not find gem 'rack-webconsole-pry'.
Did you mean rack-webconsole-pry?

2 个答案:

答案 0 :(得分：2)

bundle env的输出结果显示：

Bundler settings
  without
    Set for your local app (/Users/cweilemann/Projects/railsapp/.bundle/config): "test:development"

这意味着bundle install将跳过在development群组中安装任何内容（以及test）。

从.bundle/config文件中删除该行并再次运行bundle install，它应该开始工作。

答案 1 :(得分：0)

这似乎与rack-webconsole-pry存在问题。

这是Gemfile：

source "https://rubygems.org"

group :development do
  gem 'rack-webconsole-pry', :require => 'rack-webconsole'
end

这里将这些宝石安装到没有宝石的Rubygems系统宝石中，一切正常：

$ bundle install --system
Using coderay 1.1.0
Using multi_json 1.10.1
Using method_source 0.8.2
Using json 1.8.1
Using rack 1.5.2
Using bundler 1.7.5
Using slop 3.6.0
Using pry 0.10.1
Using rack-webconsole-pry 0.1.9
Your bundle is complete!
Use `bundle show [gemname]` to see where a bundled gem is installed.
$ bundle check
The Gemfile's dependencies are satisfied
$ bundle exec bundle check
The Gemfile's dependencies are satisfied

在这里，我将这些宝石安装到路径而不是系统宝石中，一切都破坏了：

$ bundle install --path gems
Fetching gem metadata from https://rubygems.org/..........
Using bundler 1.7.5
Installing method_source 0.8.2
Installing slop 3.6.0
Installing coderay 1.1.0
Installing rack 1.5.2
Installing multi_json 1.10.1
Installing pry 0.10.1
Installing json 1.8.1
Installing rack-webconsole-pry 0.1.9
Your bundle is complete!
It was installed into ./gems

$ bundle check
The Gemfile's dependencies are satisfied

$ bundle exec bundle check
Could not find coderay-1.1.0 in any of the sources
Run `bundle install` to install missing gems.

当它被加载时，rack-webconsole-pry以某种方式做了一些破坏宝石加载方式的东西，这使得之后无法加载宝石。当你将它移出开发组时，它并不是必需的，所以一切都很好。当你把它放在开发组中时，它会被加载，但是会破坏加载gem的方式，然后它就再也找不到实际安装的gems来加载它们了。
