That got past the gulp error. Thanks. Please explain why this change? Now there are other errors that produce a blank page with "Cannot Get /" in the browser:

Well, I didn't actually try to restore the NPM packages. As you can see from the screenshot, I ran "npm start" from the command line after having run yarn. The npm start command failed (as shown above). It was only after I then returned to Visual Studio that I got the "build delayed..." message.
The point is that "npm start" failed with the abovementioned error:
cannot find module ...\gulp.js
How do I resolve the npm error?
