Ruby on rails Rails phusion混乱-缺少源文件，但是哪一个？我怎么知道？

我发现phusion的错误信息非常令人困惑，也许我没有找准正确的地方，但几乎我遇到的每一个错误都会得到同样的信息

正在寻找一些指导

我使用SSH连接到服务器，并运行捆绑安装，以确保我的capistrano错过了一个步骤，我还执行了rake db:setup和rake db:migrate RAILS\u ENV=production

这个错误消息看起来很离谱，我甚至看不到关于哪个文件丢失的提示

我在rails 3应用程序中运行ubuntu、nginx、phusion、ree：

我的setup\u load\u path.rb看起来像：

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

我的boot.rb看起来像：

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

需要“rubygems”

# 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)

错误来自您的

config/setup\u load\u path.rb

。我猜您使用此文件为乘客设置RVM支持。我还想它包括两个捆绑包，比如：

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

…现在应该是：

require 'bundler'
Bundler.setup

猜猜看……如果不是这样的话，请编辑并将setup\u load\u paths.rb的内容放到问题中。

因此我假设您已经注释掉了较低的部分，而保留了第一部分。在您的服务器上，

bundle-v

说了什么？乘客使用的rvm gemset中是否有不同的版本？进入irb，执行“require bunder”时，我会得到相同的错误。如何在web应用程序中设置GEM_HOME？我从中获得了GEM_HOME潜在的解决方案：我的根目录中有一个.rvmrc，因此两者都使用相同的ruby+gemset。我运行的是rails 3.0.3 btw和REE
