ESM packages need to be imported

Why This Error Occurred

Packages in node_modules that are published as EcmaScript Module, need to be imported via import ... from 'package' or import('package').

You get this error when using a different way to reference the package, e. g. require().

Possible Ways to Fix It

1. Use import or import() to reference the package instead. (Recommended)

2. If you are already using import, make sure that this is not changed by a transpiler, e. g. TypeScript or Babel.

3. Switch to loose mode (experimental.esmExternals: 'loose'), which tries to automatically correct this error.
