Rails phusion混淆 - 源文件丢失，但哪一个？我怎么知道？

Question

我发现phusion的错误信息非常混乱，也许我没有在正确的位置寻找，但几乎每一个我偶然发现的错误都会得到同样的信息。

寻找一些指导！

我SSH'd到服务器，并运行捆绑安装只是为了确保我的capistrano错过了一个步骤，我还做了一个rake db：setup和rake db：migrate RAILS_ENV = production。

这个错误信息似乎很讽刺，我什至不知道哪些文件丢失的提示？

我运行Ubuntu，nginx的，PHUSION，稀土元素，在Rails 3应用程序：

Error message:

我setup_load_paths.rb样子：

if ENV['MY_RUBY_HOME'] && ENV['MY_RUBY_HOME'].include?('rvm') 
    begin 
    rvm_path  = File.dirname(File.dirname(ENV['MY_RUBY_HOME'])) 
    rvm_lib_path = File.join(rvm_path, 'lib') 
    $LOAD_PATH.unshift rvm_lib_path 
    require 'rvm' 
    RVM.use_from_path! File.dirname(File.dirname(__FILE__)) 
    rescue LoadError 
    # RVM is unavailable at this point. 
    raise "RVM ruby lib is currently unavailable." 
    end 
end 

而且我的boot.rb样子：

需要 'RubyGems的'

# Set up gems listed in the Gemfile. 
gemfile = File.expand_path('../../Gemfile', __FILE__) 
begin 
    ENV['BUNDLE_GEMFILE'] = gemfile 
    require 'bundler' 
    Bundler.setup 
rescue Bundler::GemNotFound => e 
    STDERR.puts e.message 
    STDERR.puts "Try running `bundle install`." 
    exit! 
end if File.exist?(gemfile)  

Answer 1

错误来自您的config/setup_load_paths.rb。我猜测你使用这个文件来搭建RVM支持的乘客。我还猜想，这包括两个捆绑包括，像：

require 'bundler' 
require 'bundler/setup' 
Bundler.setup 

...现在应该仅仅是：

require 'bundler' 
Bundler.setup 

只是猜测......如果不是这种情况，编辑并把内容你的setup_load_paths.rb在问题中。
