  Usually this hAPPens when watchman isn't running. Create an empty `.watchmanconfig` file in your project's root folder or initialize a git or hg repository in your project.

解决方式

删除 watchman (之前用 brew装的):

$ brew install rmtree //我的这句报错，用的 
                      //brew tap beeftornado/rmtree
$ brew rmtree watchman
$ sudo rm -rf /usr/local/var/run/watchman

Manually install Watchman v4.7.0 (credits to David):

$ git clone https://github.com/facebook/watchman.git
$ cd watchman
$ git checkout v4.7.0  //我用的时候，master就是4.7，所以没必要切branch
$ ./autogen.sh
$ ./configure
$ make
$ sudo make install

Chmod your user’s watchman state directory:

//我这个没用，直接就可以跑起来了。
$ chmod 0700 /usr/local/var/run/watchman/<user>-state
