I have setup a pre-commit and pre-push hook that runs `npm test`, which in turns executes `gulp test` on my project.
By running the hook manually in the git bash (`.git/hooks/pre-push`) the test passes, also by running git push or git commit.

When committing and pushing with SourceTree, since updating to 1.8.2.2, I get the following error message:

running lint...failed!
./node_modules/.bin/gulp: line 12: node: command not found

That line has:

node  "$basedir/../gulp/bin/gulp.js" "$@"

The hooks have been setup automatically with the npm library https://www.npmjs.com/package/precommit-hook.
