运行ReactNative工程watchman运行错误

在运行RN工程的时候执行react-native run-android的时候控制台一只出现这个玩意儿~~

Watchman:  watchman--no-pretty get-sockname returned with exit code 1 ERROR: Unknown option --no-pretty

解决方法：

npm下面的包也有watchman,如果安装了先卸载

npm r -g watchman

brew uninstall watchman 
brew link pcre 
brew install --HEAD watchman

然后安装不了出现了错误

Error: An unexpected error occurred during the `brew link` step
The formula built, but is not symlinked into /usr/local
Permission denied @ dir_s_mkdir - /usr/local/Frameworks

Error: Permission denied @ dir_s_mkdir - /usr/local/Frameworks

此时尝试解决方案：

brew link --overwrite watchman  继续报错

Error: No such keg: /usr/local/Cellar/watchman

解决方案开放权限：

sudo chown -R whoami /usr/local

sudo mkdir /usr/local/Frameworks

sudo chown $(whoami):admin /usr/local/Frameworks

 brew link --overwrite watchman  然后提示变为：

Error: No such keg: /usr/local/Cellar/watchman

重新安装：

npm install watchman  Ok了
