npm ERR! Make sure you have the latest version of node.js and npm installed.
npm ERR! If you do, this is most likely a problem with the pathwatcher package,

npm ERR! Tell the author that this fails on your system:

npm ERR! You can get information on how to open an issue for this project with:
npm ERR! npm bugs pathwatcher
npm ERR! Or if that isn't available, you can get their info via:
npm ERR! npm owner ls pathwatcher
npm ERR! There is likely additional logging output above.

npm ERR! code 1

Start by reviewing the reported npm-debug.log and the node-gyp rebuild commands for bufferutil, utf-8-validate, and pathwatcher. Reproduce the Atom package installation on the reported Darwin setup, then determine whether the installation completes without the Python-version and pathwatcher errors shown.
