我正在尝试使用--livereload选项在我的Android设备上运行一个全新的Ionic2应用程序，但出现错误。
安装命令：
$ ionic start ionic2-speed-test-run --v2
$ cd ionic2-speed-test-run/
$ cordova platform add android
如果我这样做：
$ ionic run android
该应用程序在我的Android设备上正常运行，但是如果我这样做：
$ ionic run android -l
然后我得到以下错误输出：
$ ionic run android -l

关于如何使--livereload工作的任何想法？
当您已经在使用具有相同 IP 地址的实时加载时，会发生这种类型的错误。 只需杀死其他正在运行的离子应用程序并试试运气。
如果仍然收到此错误，请重新启动系统并重试。
最后但最不重要的
将我的科尔多瓦和离子升级到最新版本，然后它工作得很好。 只是把它当作最后的希望。
我已经为我的离子应用程序使用了最后一个选项。
当实时重新加载 url 已在使用中时，会出现此消息。可能是您正在运行$ ionic serve命令并尝试$ ionic run android -l关闭所有正在运行的程序，然后重试。如果问题未解决，请尝试重新启动系统。它将强制关闭您的所有应用程序。您可以尝试将 Ionic 降级到版本 2。
