Fix error 400 bad request when trying to use create-react-app

While attempting to create a new ReactJS app with the create-react-app tool, I encountered the following error: "error 400 Bad Request: run-async@^2.2.0". See the screenshot below.

After some research, I found the node npm cache could be corrupted. So running the following command fixed the issue for me.

$ npm cache verify

The create-react-app tool now can complete successfully, as shown below:
$ npx create-react-app myapp
