无法加载这样的文件 - bundler / setup（LoadError） [英] cannot load such file -- bundler/setup (LoadError)

问题描述

我使用Ruby 2.0设置了Rails 4应用程序，但是我得到了Web应用程序无法启动并获取此跟踪：

 无法加载这样的文件 -  bundler / setup（LoadError）
 /usr/local/lib/ruby/site_ruby/2.0.0/rubygems/core_ext/kernel_require.rb:53:in`require '

 /usr/lib/ruby/gems/1.8/gems/passenger-4.0.19/helper-scripts/rack-preloader.rb:28:in`< main>'
  

我的apache2.conf是：

  LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-4.0.19/buildout/apache2/mod_passenger.so 
 PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger -4.0.19 
 PassengerDefaultRuby / usr / local / bin / ruby​​ 
  

bundle -v 是：

  Bundler版本1.3.5 
  

ruby​​ -v 是：

  ruby​​ 2.0.0p247（2013-06-27 revision 41674）[x86_64-linux] 
  

gem env 是：

 <$ c $ RubyGems环境：
  -  RUBYGEMS版本：2.1.5

  -  / usr / bin / X11

  -  / usr / sbin 
  -  / sbin 
  

< echo $ GEM_PATH 是：

  / usr / lib / ruby /gems/1.8:/usr/lib/ruby/gems/1.8 
  

不应该 GEM_PATH be /usr/lib/ruby/gems/2.0 ？

在apache2.conf中的虚拟主机中添加：

  SetEnv GEM_HOME /usr/lib/ruby/gems/1.8 
  

现在它正在工作。

解决方案的正确方法是什么？解决方案

这可能是因为在安装之前在系统上安装了以前的Ruby env 2.0的？这可能有一个现有的GEM_PATH，导致/1.8目录仅安装2.0版本。

然后，您可能遇到的问题是Passenger / Apache正在查看/2.0目录，实际上这些gem位于/1.8目录中。您明确地告诉apache使用/1.8目录对于解决这个问题是有意义的。

  SetEnv GEM_HOME / usr / lib / ruby /gems/1.8 
  

您也可以尝试使用 Ruby Version Manager 来处理多个Ruby环境。

我在Google中找到的一些东西：

I'm setting Rails 4 application with Ruby 2.0, but I'm getting "Web application could not be started" and get this trace:

cannot load such file -- bundler/setup (LoadError)

My apache2.conf is:

LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-4.0.19/buildout/apache2/mod_passenger.so
   PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-4.0.19
   PassengerDefaultRuby /usr/local/bin/ruby

bundle -v is:

Bundler version 1.3.5

ruby -v is:

ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux]

gem env is:

RubyGems Environment:
  - RUBYGEMS VERSION: 2.1.5
  - RUBY VERSION: 2.0.0 (2013-06-27 patchlevel 247) [x86_64-linux]

echo $GEM_PATH is:

/usr/lib/ruby/gems/1.8:/usr/lib/ruby/gems/1.8

Shouldn't GEM_PATH be /usr/lib/ruby/gems/2.0?

Inside the virtual host in apache2.conf I added:

SetEnv GEM_HOME /usr/lib/ruby/gems/1.8

And now it is working.

Is it the right way to fix this?

解决方案

It could be that there was a previous Ruby env installed on your system prior to your installation of 2.0? This might have had an existing GEM_PATH that lead to the /1.8 directory which the installation of version 2.0 simply kept.

The problem you where likely having, then, was that Passenger/Apache was looking in the /2.0 directory when in fact the gems were in the /1.8 directory. Your explicitly telling apache to use the /1.8 directory thus makes sense to fix the problem.

SetEnv GEM_HOME /usr/lib/ruby/gems/1.8

You might also try using the Ruby Version Manager to handle multiple Ruby envs.
