Answer 1

Try reinstalling watchman:

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

If that doesn't fix it, try the answers 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
