Chef-client 似乎无法运行 bundle install

Question

我正在尝试使用 application_ruby cookbook 在 Chef 设置的服务器上部署我的 Rails 应用程序。当 chef-client 到达运行 bundle install 的点时，它崩溃了，说它找不到 bundler。我怀疑这可能与我在此服务器上使用 RVM 的事实有关，但我不确定该怎么做。

这是我的应用配方：

database_name = "app_#{node.chef_environment}"
api_deploy_key = Chef::EncryptedDataBagItem.load('keys', 'app_repository')["deploy_key"]

application "my_app" do
  path "/var/www"
  owner 'ubuntu'
  repository "git@github.com:my_account/app.git"
  revision node.chef_environment == "production" ? "master" : "develop"
  deploy_key api_deploy_key

  rails do
    gems [['Bundler', '1.3.4']]
    database_master_role 'db_master'
    database do
      database database_name
      username "ubuntu"
      password Chef::EncryptedDataBagItem.load('passwords', 'db')["password"]
    end

    bundler true
    precompile_assets true
  end
end

这是它产生的错误：

如果我将rollback_on_error设置为false，我可以手动进入签出的代码目录，运行bundle install没有问题。

这里出了什么问题，我该如何解决？

你的环境设置错了，应该是：

environment {
  "RAILS_ENV"=>"staging", 
  "PATH"=>"/usr/local/rvm/gems/ruby-1.9.3-p125/bin:/usr/local/rvm/gems/ruby-1.9.3-p125@global/bin:/usr/local/rvm/rubies/ruby-1.9.3-p125/bin:/usr/local/rvm/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games", 
  "GEM_PATH"=>"/usr/local/rvm/gems/ruby-1.9.3-p125:/usr/local/rvm/gems/ruby-1.9.3-p125@global", 
  "GEM_HOME"=>"/usr/local/rvm/gems/ruby-1.9.3-p125"
