yarn.lock prevents deploying the hello-world appengine sample

[newbreedofgeek]

If you follow this tutorial:
https://cloud.google.com/nodejs/getting-started/hello-world

You will hit an issue when you try and gcloud app deploy which fails.

This is because of this yarn.lock file:
https://github.com/GoogleCloudPlatform/nodejs-docs-samples/blob/master/appengine/hello-world/yarn.lock

The error you see will be:

ERROR: Yarn checker: "yarn.lock" was found indicating Yarn is being used, but "yarn check" indicates "yarn.lock" is invalid.
ERROR: (gcloud.app.deploy) Your application does not satisfy all of the requirements for a runtime of type [nodejs].  Please correct the errors and try again.

No sure why this is checkin here as the tutorial uses npm.

Removing the file locally before deploying will fix the issue.

I have updated the tutorial to include instructions about using Yarn, and I have I've updated the dependencies in this repo such that the yarn check --strict-semver --integrity command should succeed during deployment.

On this tutorial - Run MongoDB on Google Cloud Platform:
https://cloud.google.com/nodejs/resources/databases/mongodb

I also hit an issue when executing "gcloud app deploy", which failed in errors that are same as above.

It seems this page lacks this step!

or just remind to install yarn first, and use "yarn install", then "yarn start" :)

Good catch, I'll update this tutorial as well
