Anyone know what's wrong?

Answer 1

Try npm i -D @types/express-serve-static-core, enable skipLibCheck is not a good idea.

Answer 2

Add "skipLibCheck": true in tsconfig.json. It worked for me.

Answer 3

skipLibCheck is rather a workaround and you should not include it without knowing what you are doing.

The issue is fixed in the latest versions so if you have @types/express install update it to latest npm i -D @types/express@latest or install @types/express-serve-static-core explicitly with npm i -D @types/express-serve-static-core

You can check which version the @types/express-serve-static-core has with:

$ npm ls @types/express-serve-static-core
