title: When trying to run a jest test, I receive the error "sh: jest: command not found"
body: <p>Im working on a node command line application which requires jest testing.  Ive installed it as a dependency in my package.json, and when I try to run the 'npm run test' command, it gives me a bunch of errors.  Anyone know what's going on?  Im very new to node and web dev in general, so any feedback would be much appreciated!</p>
