Occasionally, typescript may generate a definition file with code like the following, leading to compile errors:
// issue.ts
import { Observable } from 'rxjs';
class Issue {
get data() {
return new Observable();
}
}
// issue.d.ts
class Issue {
data: import("rxjs").Observable<any>;
}
What causes this issue and what steps can be taken to identify and fix these kinds of errors?
import("rxjs").Observable<any>;2.9 and above. Issues with this syntax typically arise when attempting to use a definition generated by a newer version of typescript (which utilizes the import type syntax) in an older version.
As previously mentioned in the discussions, it appears that this was indeed the issue you were facing. The recommended solution would be to ensure that both the library and application are utilizing the same version of TypeScript.
