【问题描述】：

我正在尝试与乘客一起运行 redmine。我运行了以下命令：

sudo passenger start RAILS_ENV=production

并得到以下异常：

Stopping web server.../var/lib/gems/1.9.1/gems/daemon_controller-1.1.5/lib/daemon_controller/lock_file.rb:63:in `initialize': No such file or directory - /usr/share/nginx/www/redmine-install/RAILS_ENV=production/passenger.3000.pid.lock (Errno::ENOENT)

我已经通过以下方式安装了带有 nginx 的乘客（在带有 raspbian 的树莓派上）：

Recompile nginx with passenger support as the standard ubuntu version doesn't have it.

sudo gem install passenger --no-ri --no-rdoc
sudo passenger-install-nginx-module
sudo passenger

Choose /usr/local/nginx as installation directory.

Change the following line in /etc/init.d/nginx:
#DAEMON=/usr/sbin/nginx
DAEMON=/usr/local/nginx/sbin/nginx

In /etc/nginx/nginx.conf add the following to the http section:

passenger_root /var/lib/gems/1.9.1/gems/passenger-4.0.18;
passenger_ruby /usr/bin/ruby1.9.1;

我不确定如何解决此错误。一些帮助将不胜感激！

【解决方案1】：

您调用了passenger start 错误。正如您在passenger start --help 中看到的，它接受一个可选参数[directory]，它指向应用程序目录。您实际上是在告诉它应用程序目录位于RAILS_ENV=production，这显然不是有效目录。

设置 RAILS_ENV 的正确方法是通过 --environment 选项。见--help。
