Angular 6
how can i resolve this?
You should the latest (12+) node when upgrading to angular 8. You can download it from here.
After upgrading node, the issues should go away.
For simple use cases and thanks to the work done in Angular 8, you can upgrade to the latest release using one command:
$ ng update @angular/cli @angular/core
After running this command, the lazy loaded routes will be automatically migrated to the new import syntax which is standard compliant and brings Angular close to the open web platform.
You also need to be aware of the following issues when upgrading your project:
Angular 8 makes use of the latest TypeScript 3.4, so even if the upgrade process completes with success you might have some syntax errors that may be due to the better type inference system used by the latest version which detects new potential typing issues but in the end this will improve your code quality and helps you avoid bugs in the future. You can see the new features of TypeScript 3.4 from the official docs.
You need to have Node.js 12+. Simply run node -v to verify your Node version. You can install the latest version from the official website
