It seems like it is a vue-cli problem, so I am posting this issue.

What is expected?

Building without warnings and errors

What is actually happening?

I got an error like described in the stackoverflow link. (Unexpected token when the private keyword is used)

Sorry - cleaned up my code a lot and adopted my "old code" to a new one created by vue create with typescript from the begin.

Now the problem is solved and tslint shows no errors anymore.
Thank you 👍
