Error installing package

Having this error when trying to install the package:
`npm WARN deprecated lodash.isarray@4.0.0: This package is deprecated. Use Array.isArray.
npm WARN deprecated node-uuid@1.4.8: Use uuid module instead
npm ERR! Error while executing:
npm ERR! /usr/bin/git ls-remote -h -t ssh://git@github.com/ramitos/tern-jsx.git
npm ERR!
npm ERR! xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
npm ERR!
npm ERR! exited with error code: 1`

Start by reproducing the package installation with npm and inspect the reported git ls-remote request for ramitos/tern-jsx. Check how the xcrun developer-path error affects the install, then establish whether a successful npm install is possible and document the verified outcome.
