我在我的Apache服务器上使用Phusion Passenger和Ruby on Rails时遇到了以下错误消息：
It looks like Bundler could not find a gem. This is probably because your
application is being run under a different environment than it's supposed to.
Please check the following:
* Is this app supposed to be run as the `rvm_admin` user?
* Is this app being run on the correct Ruby interpreter? Below you will
see which Ruby interpreter Phusion Passenger attempted to use.
* Are you using RVM? Please check whether the correct gemset is being used.
* If all of the above fails, try resetting your RVM gemsets:
https://github.com/phusion/passenger/wiki/Resetting-RVM-gemsets
-------- The exception is as follows: -------
Could not find json-1.8.1 in any of the sources (Bundler::GemNotFound)
当我执行 gem list 命令时，感觉很奇怪：
rvm_admin@myserver:~$ gem list

JSON似乎在这里出现了
但是如果我执行一个
rvm_admin@myserver:~$ bundle show json
Could not locate Gemfile
为什么会这样呢？以下是我的gemsets信息：
rvm_admin@myserver:~$ rvm gemset list
gemsets for ruby-2.1.0 (found in /usr/local/rvm/gems/ruby-2.1.0)
=> (default)
global
因此除了全局设置外，没有其他的gemsets。
这是我的Gemfile：
source 'https://rubygems.org'
gem 'rails', '~>3.2'
gem 'pg', '>= 0.14'
gem 'haml-rails' , '>= 0.3'
gem 'execjs'
gem 'therubyracer', :platforms => :ruby
group :development, :test do
gem 'factory_girl_rails'
end
group :developpement do
gem 'rspec-rails', '~> 2.11'
gem 'capistrano', '~> 3.0.1'
gem 'faker', '>= 1.0'
gem 'sshkit', '~> 1.0.0'
end
group :test do
gem 'rspec', '>= 2.11'
gem 'webrat', '>= 0.7'
gem 'spork-rails', '>= 3.2'
end
group :assets do
gem 'sass-rails', '>= 3.2.3'
gem 'coffee-rails', '>= 3.2.1'
gem 'compass-rails', '>= 1.0'
gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
gem 'annotate'
gem 'spreadsheet' #, '~> 0.7'
gem 'schema_plus' #, :git => "git://github.com/lomba/schema_plus.git"
gem 'squeel' #, '~> 1.0'
gem 'devise' #, '~> 2.1'
gem 'role_model'
gem 'declarative_authorization'
gem 'rails-translate-routes' #, '~> 0.1'
gem 'validates_timeliness' #, '~> 3.0'
我使用命令
bundle install --without developement test 手动安装宝石(gems)。我不想让Capistrano执行任何服务器软件包安装，因此我卸载了capistrano-rvm或capisttrano-rails等gems。
出了什么问题？我该怎么做？
=== 编辑
如果我进入我的应用程序文件夹并检查Json是否存在，它似乎存在:
rvm_admin@myserver:/var/www/odpf/current$ bundle show json
The gem json has been deleted. It was installed at:
/usr/local/rvm/rubies/ruby-2.1.0/lib/ruby/gems/2.1.0/gems/json-1.8.1
gem 'json'吗？（修改Gemfile后再次运行bundle install） - Thomas Klemm
