As per comment on issue https://github.com/angular/angular-cli/issues/2034

having the same issue. (Works fine despite warning) are you exporting more than one interface/class/const from the file? issue stopped for me after i exported each interface from its own dedicated file.

meaning if i had one file with multiple exports - i got warnings in build (export 'MyInterface1' was not found in '../file')

file.ts

export interface MyInterface1 {}
export interface MyInterface2 {}

after refactor - no warning

file1.ts

export interface MyInterface1 {}

file2.ts

export interface MyInterface2 {}
