When using node-fetch-cjs as a dependency in a TypeScript project, I get the following errors during compilation:

The workaround for this is to set skipLibCheck to true in tsconfig.json:
Unfortunately this workaround "pollutes" the dependency chain, i.e. any package that uses a package that uses node-fetch-cjs will have to do this.
