我试图将passenger_root和passenger_ruby添加到我的nginx.conf文件中，但是当我尝试并重新启动NGINX时，我收到消息：
Starting nginx: nginx: [alert] Unable to start the Phusion Passenger watchdog because its executable (/usr/lib/phusion-passenger/agents/PassengerWatchdog) does not exist. This probably means that your Phusion Passenger installation is broken or incomplete, or that your 'passenger_root' directive is set to the wrong value. Please reinstall Phusion Passenger or fix your 'passenger_root' directive, whichever is applicable. (-1: Unknown error) nginx. 在我的nginx.conf文件中：
http { passenger_root /home/deploy/.rvm/gems/ruby-2.0.0-p247/gems/passenger-4.0.14; passenger_ruby /home/deploy/.rvm/wrappers/ruby-2.0.0-p247/ruby;
这些都是有效的path
我看了这个post： nginx-not-acknowledging-passenger-root-option并试图运行
apt-get remove nginx
但它告诉我nginx没有安装。 我正在使用RVM + Passenger + Nginx
我通过运行gem安装乘客安装乘客。 Nginx之前已经安装好了，我只是尝试在nginx.conf文件中修改乘客的新版本的path。 我需要额外做些什么来使这两个工作在一起吗？
如果我尝试运行sudo passenger-install-nginx-module
我收到消息：
Nginx with Passenger support was successfully installed. Please edit your Nginx configuration file (probably /opt/nginx/conf/nginx.conf), and set the passenger_root and passenger_ruby configuration options in the 'http' block, like this: http { ... passenger_root /var/lib/gems/1.9.1/gems/passenger-3.0.19; passenger_ruby /usr/bin/ruby1.9.1; ... }
那是旧的rubypath…如果我运行rvm信息，我得到适当的ruby2.0path
