TypeScript error “Interface 'NodeBuffer' incorrectly extends interface 'Uint8Array'”

Question

When I'm trying to compile my Angular application I get this error:

ERROR in ...\src\page-sidebar\typings\browser\ambient\node\index.d.ts (426,11): error TS2430: Interface 'NodeBuffer' incorrectly extends interface 'Uint8Array'. Types of property 'fill' are incompatible. Type '(value: any, offset?: number, end?: number) => Buffer' is not assignable to type '(value: number, start?: number, end?: number) => this'. Type 'Buffer' is not assignable to type 'this'.

My TypeScript and typings are updated to latest versions:

"typescript": "2.1.6",
"typings": "2.1.0

Does anyone know where could be the problem?

The best thing to do with errors like this is to search for the text of the error online. I did, and found that, perhaps, reinstalling the node typings would help: garysieling.com/blog/…. Otherwise, you can log the error at github.com/types/env-node/issues. — Heretic Monkey
In order to check what the problem is we need to see the code of index.d.ts — RefaelJan

Try updating the typing definitions for Node. Running typings i env~node -SG worked for me. I found the solution here https://github.com/typings/typings/issues/554

Hope it helps.
