Common Issue for Parse-server Upgrade

This is a common error during upgrade of parse-server.  After upgrade, the npm start may ends with error like this: "Cannot find module 'double-ended-queue'".

If you run npm list, you will see some missing modules such as the followings:

npm ERR! missing: double-ended-queue@^2.1.0-0, required by redis@2.8.0
npm ERR! missing: redis-commands@^1.2.0, required by redis@2.8.0
npm ERR! missing: redis-parser@^2.6.0, required by redis@2.8.0

 You can try to delete the package-lock.json and node_modules folder, following by re-install.

rm -rf package-lock.json node_modules/
npm i --no-optional
npm dedupe
npm up
