Could you recreate your app in Stackblitz or show us some code from `app.module.ts` `app.component.ts` — Sergey, Jan 25 '19 at 17:31

This could be because your version of TypeScript needs to be updated.

See this question here: #42301181 Initializers are not allowed in ambient contexts

Try compiling your project with the newest version of TypeScript.

I had the same issue and I solved it updating typescript version:

After change it delete node_modules folder, restore it back using npm install and rebuild solution.

I resolved this by adding :

skipLibCheck": true

to the compiler options in the tsconfig.json.
