node-fetch: The requested module does not provide an export named 'PassThrough'

Calling fetch gives me the following error

node_modules/node-fetch/lib/index.mjs:1
import Stream, { PassThrough } from 'stream';
                 ^^^^^^^^^^^
SyntaxError: The requested module does not provide an export named 'PassThrough'

The published ESM in lib/index.mjs contains this line:

import Stream, { PassThrough } from 'stream'

Turns out, PassThrough is not a named export of stream in Node.js v8, but it is in v10:

// test.mjs
import { PassThrough } from 'stream'

node --experimental-modules test

In Node.js v8.12.0:

$ node --experimental-modules test
(node:32448) ExperimentalWarning: The ESM module loader is experimental.
SyntaxError: The requested module does not provide an export named 'PassThrough'

In Node.js v10.11.0:

$ node --experimental-modules test
(node:32605) ExperimentalWarning: The ESM module loader is experimental.
