客观的：
我试图让热重载工作，我在代码库中进行了更改，并且更改出现在 android 模拟器中，如广告所示。
问题：
它不起作用，我感觉它与 facebook watchman 有关。每次我对代码库进行更改时，react-native 服务器都会说
[sane] Warning: Lost connection to watchman, reconnecting..
[sane] Warning: Lost connection to watchman, reconnecting..
[sane] Warning: Lost connection to watchman, reconnecting..
etc....
顺便说一句：是的，我从 android 模拟器的开发者菜单中启用了热重载
操作系统：
Ubuntu 14.04.5 LTS
守望者：
watchman watch-list

"version": "4.7.0",
"roots": [
"/home/andey/Downloads/wyse"
]
}
反应原生：
react-native -v
react-native-cli: 1.2.0
