领域错误 - _constructor必须是'function'类型,得到(undefined)

Question

我正在尝试使用我的本机应用程序在本地设置Realm DB,但似乎有一个错误,我无法找出原因.我在这里遵循了文档和指南.

我的守则.

import Realm from 'realm';

export const ConfigSchema = {
    name: 'Config',
    primaryKey: 'key',
    properties: {
        key: 'string',
        value: 'string'
    }
};

export const databaseOptions = {
    path: 'myappreactnative.realm',
    schema: [ConfigSchema],
    schemaVersion: 0
};

export const insertNewConfig = (newConfig) => new Promise((resolve, reject) => {
    Realm.open(databaseOptions).then(realm => {
        // realm.create('Config', newConfig);
        // resolve(newConfig);
        console.log(realm);
    }).catch((error) => reject(error))
});

我在insertNewConfig这里打电话,

let config = {
    key: 'instanceUrl',
    value: 'myurl.domain.value'
};

insertNewConfig(config).then((result) => {
    console.log(result);
}).catch((error) => {
    console.log(error);
});

this.props.navigation.navigate('Login', {});

错误就在那里Realm.open(databaseOptions).首先,我虽然错误与realm.create但后来实现了原始线.

显示的错误是这样的.

Error: _constructor must be of type 'function', got (undefined)
    at sendRequest (rpc.js:263)
    at Object.createRealm (rpc.js:62)
    at new Realm (index.js:102)
    at Function.open (extensions.js:110)
    at eval (eval at <anonymous> (MetroClient.js:63), <anonymous>:29:22)
    at tryCallTwo (core.js:45)
    at doResolve (core.js:200)
    at new Promise (core.js:66)
    at insertNewConfig (eval at <anonymous> (MetroClient.js:63), <anonymous>:28:12)
    at Object.SelectInstanceScreen._this.continueLogin [as onPress] (eval at <anonymous> (MetroClient.js:63), <anonymous>:74:37)

似乎open()函数必须作为函数调用(_constructor必须是'function'类型),但很明显它open()被称为函数.提前致谢.

我想也许是最后一个版本(2.18.0)上的一个错误,尝试降级到2.16.0它会起作用.
