TypeScript error: Duplicate identifier 'LibraryManagedAttributes'

Question

Failed to compile.

/moonholdings.io/node_modules/@types/react-dom/node_modules/@types/react/index.d.ts (2312,14): Duplicate identifier \'LibraryManagedAt

Answer 1

You may find that the duplicates are located in node_modules/@types/react and node_modules/types/react-dom/@types/react or a similar set-up, in which one of the packages has a nested dependency on the other.

Uninstalling and reinstalling @types/react-dom and @types/react together is what fixed it for me.

yarn remove @types/react-dom @types/react


yarn add -D @types/react-dom @types/react
