Question

我发现错误的错误信息非常令人困惑，也许我找不到正确的地方，但几乎每一个我偶然发现的错误都会得到同样的信息。

寻求指导！

我通过SSH进入服务器，并运行捆绑安装只是为了确保我的capistrano错过了一步，我还做了一个rake db：setup和rake db：migrate RAILS_ENV = production。

此错误消息似乎非常有问题，我甚至没有看到有关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_load_paths.rb如下：

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：

要求'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_load_paths.rb。我猜您使用此文件来设置具有RVM支持的乘客。我还猜测它包括两个捆绑包，类似于：

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

......现在应该只是：

require 'bundler'
Bundler.setup

猜测......如果不是这样，请编辑并将setup_load_paths.rb的内容放入问题中。

Rails错误混乱 - 源文件丢失，但是哪一个？我该怎么知道？
