nodemon: upon updating to 2.0.9^ Unhandled promise rejection warning on save while running nodemon.

• nodemon -2.0.9:
• node -12.16.3:
• OS : Windows 10
• terminal: gitbash and also in vscode terminal(poweshell)
• Not using docker
• This happens when I run "server": "cross-env NODE_ENV=development nodemon index.js", this script.

Expected behaviour

I expect nodemon to restart and track my changes.

Actual behaviour

nodemon throws an unhandled promise rejection warning on save.

I updated to 2.0.9 because of the closing response on issue #1854

Now nodemon still fails to restart, but it does so with this new unhandled promise rejection.

I tried a few different methods of updating nodemon like npm install nodemon@latest and npm update nodemon. And also tried uninstalling it completely both locally and globally. Then reinstalling

I will also make a note that the unhandled promise rejection occurs on nodemon versions 2.0.8-alpha.a and up.

When I downgrade to 2.0.7 it silently fails to restart still.
