我试图让我的Rails应用程序在我的VPS上工作。 我部署了我的项目，创build了数据库并迁移了它。 但是当我访问该页面时，我收到一条消息：
We're sorry, but something went wrong. We've been notified about this issue and we'll take a look at it shortly. 我的nginx错误日志告诉我这个：
App 12380 stdout: App 12380 stderr: *** ERROR ***: Cannot execute /home/deploy/.rvm/wrappers/ruby-2.1.2/ruby: No such file or directory (2) [ 2014-11-03 11:44:12.9549 12050/7fd1a0bb8700 Pool2/Implementation.cpp:287 ]: Could not spawn process for application /home/deploy/wisemonkeys/current: An error occurred while starting up the preloader.

我试着去读https://github.com/phusion/passenger/wiki/Debugging-application-startup-problems，但是现在对我来说太过于技术了。
发现问题。 我没有使用RVM /home/deploy/.rvm/wrappers/ruby-2.1.2/ruby:在我的/etc/nginx/nginx.conf我有
passenger_ruby /home/deploy/.rvm/wrappers/ruby-2.1.2/ruby;
但我需要有：
passenger_ruby /home/deploy/.rbenv/shims/ruby;
