Answer 1

I started getting this error after i used

ng update

and I resolved the issue by reverting my package.json to the previous version of angular,

I downgraded from 6.1.3 to 6.0.7

Answer 2

I have the same error in angular 5. this works for me

ng build --prod --aot=false

another solution I upgrade my ng version from 5.1.0 to version 5.1.1. it solve the problem without adding --aot=false option.

Answer 3

I had the same issue. Try the build by disabling aot and see if it works. Use ng build --prod --aot=false. If this works then you might want to refer to the link below. It looks like there is a bug, upgrading angular and/or cli should fix it.
