“Super expression must either be null or a function, not object” error

问题

I use example code from https://github.com/realm/realm-js/blob/master/examples/ReactExample/components/realm.js.

'use strict';

import Realm from 'realm';

class Todo extends Realm.Object {}
Todo.schema = {
    name: 'Todo',
    properties: {
        done: {type: 'bool', default: false},
        text: 'string',
    },
};

class TodoList extends Realm.Object {}
TodoList.schema = {
    name: 'TodoList',
    properties: {
        name: 'string',
        items: {type: 'list', objectType: 'Todo'},
    },
};

export default new Realm({schema: [Todo, TodoList]});

When I run this, I got

Super expression must either be null or a function, not object

error.

I am using

"react": "^0.14.8",
"react-native": "^0.25.1",
"realm": "^0.12.0",

How can I solve this issue? Thank you for any tip!

This is fixed in the newest version 0.13.0 which is coming out shortly. You can try the release candidate now by setting the version to 0.13.0-rc in your package.json
