我正在用Ruby 2.0设置Rails 4应用程序,但是我得到“无法启动Web应用程序”并得到以下跟踪信息:
cannot load such file -- 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 version 1.3.5
ruby -v
是:
ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux]
gem env
是:

echo $GEM_PATH
是:
/usr/lib/ruby/gems/1.8:/usr/lib/ruby/gems/1.8
不GEM_PATH
应该/usr/lib/ruby/gems/2.0
吗?
在apache2.conf的虚拟主机中,我添加了:
SetEnv GEM_HOME /usr/lib/ruby/gems/1.8
现在它正在工作。
这是解决此问题的正确方法吗?
sudo
实际必要吗?我曾经用过,sudo
但现在我想知道如果不这样做会发生什么。
