Question

我是RoR的新手，我正在尝试安装特定的项目。我的操作系统是Ubuntu 14.04，我试图从终端运行该项目。我已按照项目规范安装了所有需要的宝石。

问题

当我运行试图运行项目的命令时

foreman start -f Procfile.dev

它给我以下错误

17:01:33 web.1    | started with pid 4538
17:01:33 worker.1 | started with pid 4540
17:01:34 web.1    | /home/user/.rvm/gems/ruby-2.1.3/gems/railties-4.0.9/lib/rails/commands/server.rb:33:in `parse!': missing argument: --port (OptionParser::MissingArgument)

17:01:34 web.1    | exited with code 1
17:01:34 system   | sending SIGTERM to all processes
17:01:34 worker.1 | terminated by SIGTERM

这就是我在Procfile.dev中所拥有的：

web: bundle exec rails s --port $DEV_PORT
worker: bundle exec rake jobs:work
# exec: lt --port $DEV_PORT --subdomain $SUBDOMAIN

你能告诉我如何解决这个问题吗？

Answer 1

Foreman设置一个名为$PORT的环境变量，而不是$DEV_PORT。除非你自己设置$DEV_PORT（如果你需要像Heroku那样部署它，这将无效），你明确地用空端口启动你的进程。将您的Procfile更改为使用$PORT，您应该好好去。

使用Foreman启动Rails时丢失端口
