TypeError: Cannot read property 'slice' of undefined

[datatypevoid]

After cloning the master branch and attempting to run the tests I receive the output:

/home/user/Projects/js_bintrees/node_modules/jshint/lib/cli.js:92
        targets = typeof targets === "string" ? null : targets.slice(1);
                                                               ^
