[ionic4beta7] how to update an existing project to beta 11?

Please have a look at the following post and check out the solution from @reedrichards

I followed the second way:

rm -r node_modules
rm package-lock.json
npm install

and it worked for me. I now also use ncu as recommended to update my package.json
Please also note that you should keep typescript 2.9.2 as recommended.

I only had to change the native dependencies to “beta.14” in Ionic beta 7. Now they are …beta.21.
