我正在使用Capistrano，Unicorn，rbenv，nginx，linode，ubuntu 12.04部署我的第一个铁路应用。当我运行
时bin/cap部署：冷
在我的应用程序root中，我会收回以下错误：

我已经在开发机上运行捆绑包安装了 - 路径供应商/捆绑包，并且在Dev Machine和Linode VPS上同时安装了GEM Rake。为什么找不到耙子？
更新：
我尝试在linode上添加linode上的rake gem的路径，并在linode和：deploy.rb文件中的default_envoronment上添加。仍然遇到相同的错误...
尝试在Capistrano接收中指定您的路径，例如：
default_environment["PATH"] = "/usr/local/bin:/usr/bin:/usr/local/rvm/bin/:/var/lib/gems/1.9.1/bin"
如果您不知道如何看待您的路径，请通过SSH连接到服务器并运行命令
echo $PATH
Capistrano尝试在部署到的远程计算机上运行命令cd /home/mr_deployer/apps/prjct_mngr/releases/20121031001933 && bundle install --gemfile /home/mr_deployer/apps/prjct_mngr/releases/20121031001933/Gemfile --path /home/mr_deployer/apps/prjct_mngr/shared/bundle --deployment --quiet --without development test。
看起来远程节点没有安装rake试图使用的CC_2。
也许您应该检查所有必要的宝石都安装在远程计算机上。
此错误并未表明您部署到的机器上未安装耙子。此错误意味着，当Bundler尝试安装您的宝石时，无法在您的Gemfile中列出的来源中找到Rake版本0.9.2.2。您的Gemfile是否包含source "http://rubygems.org"之类的行？
