阵营本地`NPM start`与守望错误

Question

我第一次得到这个问题：https://github.com/facebook/react-native/issues/10088

然后我跟着这个解决方案来解决该问题：https://github.com/facebook/react-native/issues/910#issuecomment-94181845

现在，当我进入npm start我得到[sane] Warning: Lost connection to watchman, reconnecting..。有什么建议么？

更新：当我将MacOS更新到MacOS Sierra时，开始发生这种情况。

更新：所以我试图运行react-native run-ios这将打开一个新的控制台窗口和调用npm start。它仍然给出了[sane] Warning: Lost connection to watchman, reconnecting..警告，但它构建了捆绑包。所以看守人之间的连接正在中断。这里是控制台的截图：

Answer 1

我按照提供的解决方案解决了这个问题由大卫，但我不得不做一些额外的步骤，因为我已经安装了使用brew的守望者。下面是该解决方案的命令列表：（由BREW安装）

删除守望：

$ brew install rmtree 
$ brew rmtree watchman 
$ sudo rm -rf /usr/local/var/run/watchman 

手动安装柝V4.7.0（学分大卫）：

$ git clone https://github.com/facebook/watchman.git 
$ cd watchman 
$ git checkout v4.7.0 
$ ./autogen.sh 
$ ./configure 
$ make 
$ sudo make install 

您CHMOD用户的守望者状态目录：

$ chmod 0700 /usr/local/var/run/watchman/<user>-state 

Answer 2

运行项目文件夹内此命令

watchman watch-del-all && npm start --reset-cache 

Answer 3

我有一个simular问题，看日志看守我得到这些错误每次看到“丢失连接时发生给Watchman“的信息。

UPDATE： 好吧，发现迄今似乎工作的解决方案。我卸载守望完全，然后用这似乎做工精细下面从源代码编译它（通过BREW安装任何尝试会导致上述问题，但这个工程）：

$ git clone https://github.com/facebook/watchman.git 
$ cd watchman 
$ git checkout v4.7.0 # the latest stable release 
$ ./autogen.sh 
$ ./configure 
$ make 
$ sudo make install
