QUESTION: How can I resolve the Typescript Compiler (tsc) error "Namespace 'NodeJS' has no exported member 'Global'"?

While running tsc, I'm all of a sudden seeing the following error in a "legacy"(not new) project:

node_modules/expect/node_modules/@jest/types/build/Global.d.ts:85:62 - error TS2694: Namespace 'NodeJS' has no exported member 'Global'.

85 export interface Global extends GlobalAdditions, Omit<NodeJS.Global, keyof GlobalAdditions> {
                                                                ~~~~~~

I tried adding installing @types/node and adding "types": ["node"] to my tsconfig (as suggested in this SO post), but that didn't help.

Node version: 12.18.4
Jest version: 26.5.3

I was able to work around this issue by adding "skipLibCheck": true to my tsconfig.

TFM: https://www.typescriptlang/tsconfig#skipLibCheck

This is a known bug: https://github./facebook/jest/issues/11640

Downgrading to @types/node v15.14.0 seems to work around the bug for me.
