尝试重新安装守望者：

npm r -g watchman 
brew update && brew upgrade
brew install watchman

如果这不能解决问题,请尝试答案posted here.

Try to re-install libtool by:

brew reinstall libtool --universal && brew unlink libtool && brew link libtool

If won’t help,try to remove it completely and re-try above
again:

brew uninstall libtool
