Hello community,
first post here! I’m experiencing the exact same error from this post .
I have created a minimale repro on Codesandbox .
You will notice that the OP from the other post and I are both using Vite, which I believe is what is ultimately causing the issue.
The error happens here in LiveQuerySubscription.js:
var Subscription = /*#__PURE__*/function (_EventEmitter) {
(0, _inherits2.default)(Subscription, _EventEmitter); // error happens here
var _super = _createSuper(Subscription);
and it’s apparently because the following check fails in babel/runtime-corejs3/helpers/inherits.js
:
function _inherits(subClass, superClass) {
// superClass is === undefined and the error is thrown
if (typeof superClass !== "function" && superClass !== null) {
throw new TypeError("Super expression must either be null or a function");
}
subClass.prototype = _Object$create(superClass && superClass.prototype, {
constructor: {
value: subClass,
writable: true,
configurable: true
}
});
if (superClass) setPrototypeOf(subClass, superClass);
}
…since superClass
is undefined
and the strict check !== null
fails
All this is probably because Vite uses no preprocessor and instead leans on modern browsers being able to use ES6 modules? I don’t know, may be something completely different. All I know is that I don’t have this issue using the vue-cli in place of Vite… but then again, I was just migrating to Vite!!
Hope this can be solved, thanks in advance,
Stefano
