Would you be open to writing this check like this:

// Skip platforms where the error is not known.
if (!dlerror_msg)
  return true;

return e.name === 'Error' && dlerror_msg.some((msg) => e.message.includes(msg));

EDIT: Nevermind. We don't need to skip the e.name check on any platforms.

return false;
if (e.name !== 'Error')
return false;
return true;
}
);

try {
require();
} catch (e) {
assert.ok(e.toString().includes('missing path'));
}
assert.throws(
require,
/^AssertionError: missing path$/
);

try {
require({});
} catch (e) {
assert.ok(e.toString().includes('path must be a string'));
}
assert.throws(
() => { require({}); },
/^AssertionError: path must be a string$/
);
