Question

我正在尝试让我的 Rails 应用程序在我的 VPS 上运行。我已经部署了我的项目，创建了数据库并迁移了它。但当我访问该页面时，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 错误日志显示了以下内容：

App 12380 stdout:
App 12380 stderr: *** ERROR ***: Cannot execute /home/deploy/.rvm/wrappers/ruby-2.1.2/ruby: No such file or directory (2)

我尝试阅读https://github.com/phusion/passenger/wiki/Debugging-application-startup-problems，但目前对我来说太技术性了。

发现问题了。我没有使用 RVM我/home/deploy/.rvm/wrappers/ruby-2.1.2/ruby:有/etc/nginx/nginx.conf

passenger_ruby /home/deploy/.rvm/wrappers/ruby-2.1.2/ruby;

但我需要：

passenger_ruby /home/deploy/.rbenv/shims/ruby;
