我想从Polidea试用反应母语-BLE-PLX库阵营本地的,BleManager“本机模块不能为空”
https://github.com/Polidea/react-native-ble-plx
所以我创建了终端新的应用和安装通过Polidea说明过的文库
create-react-native-app playground
npm install --save react-native-ble-plx
react-native link react-native-ble-plx
我然后跑npm start
然后i
(用于在IOS模拟器开口)
,然后我得到了以下错误(在终端和在模拟器)
- 本机模块不能为空
- node_modules /反应天然/ node_modules/FBJS/LIB/invariant.js:44 :31:16在NativeEventEmitter
- node_modules /反应天然-BLE-PLX/SRC/BleManager.js:52:25在BleManager在不变
- node_modules /反应天然/库/ EventEmitter/NativeEventEmitter.js 24
- App.js:8:在应用
个- node_modules /反应天然/库/渲染器/ ReactNativeStack-dev.js:1679:33
- node_modules /反应天然/库/渲染器/ ReactNativeStack-dev.js:1610:在measureLifeCyclePerf
- 15。 ..从框架52多个堆栈帧内部构件
这里是App.js的代码:
import React from 'react';
import { StyleSheet, Text, View } from 'react-native';
import {BleManager} from 'react-native-ble-plx';
//importing BleManager without calling new BleManager() works
export default class App extends React.Component {
constructor(){
super();
this.manager = new BleManager();
}
//calling new BleManager() leads to error
render() {
return (
<View style={styles.container}>
<Text>nothing, just sucking errors</Text>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#fff',
alignItems: 'center',
justifyContent: 'center',
},
});
这里是文件的package.json

我已经找了帮助,并试图
npm -rm rf node_modules
npm install
,但它并没有帮助。
这里是我的系统信息:
MACOS海伊谢拉
的iMac(27英寸,2010年中)
处理器2.8 GHz英特尔酷睿i5
内存16 GB 1333 MHz DDR3
我也拿到了山姆(从NPM开始扫描的QR码在终端之后)开在我的iPhone应用程式(6S,10.3.1)当E错误
没有反应天然-BLE-PLX库的正常工作的其他应用程序。
期待收到一些帮助。
在此先感谢。
