我已经到了这一步,我正在使用cloud9环境.但是,当我按照该教程中的清单1.7运行服务器时,我收到此错误:

我已经尝试指定一个不同的端口,但这不起作用,cloud9环境向我建议我应该使用$ PORT变量.
错误"地址已在使用 - bind(2)为0.0.0.0:8080(Errno :: EADDRINUSE)"意味着我已经运行了一个rails服务器,但我没有.我不确定该怎么做,本教程没有提出任何解决此问题的方法.

我了解到你可以使用该命令killall ruby来阻止任何帮助我的ruby进程,因为我错误地在教程rails server -b $IP -p $PORT中的~/workspace级别运行命令.我发现答案中无法打开rails服务器
我最后再次从头开始教程并且工作正常,但是将来有这个问题的人可能会发现我从cloud9的支持团队收到的这种故障排除技术非常有用:
尝试:
lsof -i:8080
这将给予占用它的应用程序.
如果是apache,请使用以下命令停止:
sudo /etc/init.d/apache2 stop
希望这个答案对任何有此问题的人都有用.
