nodemon crashes after adding its' dependencies - mean

Question

I can't seem to track down why nodemon is crashing after it loads its dependencies and starts. I'm doing a MEAN API tutorial and I want to use it to automate restarting the node server. Any help would be greatly appreciated. Here is the stacktrace:
C:\nodeprojects\bookstore>npm install -g nodemon
C:\Users\brohj_000\AppData\Roaming\npm\nodemon -> C:\Users\brohj_000\AppData\Roaming\npm\node_modules\nodemon\bin\nodemon.js
> nodemon#1.14.11 postinstall C:\Users\brohj_000\AppData\Roaming\npm\node_modules\nodemon
> node -e "console.log('\u001b[32mLove nodemon? You can now support the project via the open collective:\u001b[22m\u001b[39m\n > \u001b[96m\u001b[1mhttps://opencollective.com/nodemon/donat
