react-native - 错误：传感器的本机模块不可用。react-native 链接是否运行成功？

Question

我是 React Native 的新手，你能帮帮我吗？我刚刚安装了 react-native-sensors（Yarn add --save react-native-sensors），然后我导入了我的项目（import { Accelerometer } from "react-native-sensors";) 但我收到了这条消息“传感器的本机模块不可用。react-native 链接是否成功运行？

我运行了命令“react-native link react-native-sensors”，但错误仍然存​​在=（

我正在使用“react-native-sensors”：“^5.1.5”。

这是我的 package.json

{
"name": "tcc_mobile",
"version": "0.0.1",
"private": true,
"scripts": {
"start": "node node_modules/react-native/local-cli/cli.js start",

},

}
}

谢谢 ！=)

Answer 1

1. $ npm install react-native-sensors --save or Yarn add
2. $ react-native link react-native-sensors

你在iOS上测试吗？如果你在 iOS 上测试，你需要添加这个。

选项：使用 CocoaPods（仅限 iOS）

将以下内容添加到您的 Podfile 并运行$ pod install:

pod 'RNSensors', :path => '../node_modules/react-native-sensors'

检查您的 AVD 的传感器功能并尝试使用真实设备。使用给定的依赖版本对我来说很好：- "react-native-sensors": "^5.1.8"。这是一个小代码片段：- import { accelerometer, gyroscope, setUpdateIntervalForType, SensorTypes } from "react-native-sensors"; accelerometer.subscribe(({ x, y, z, timestamp }) => { console.log(X：${ x }，Y：${y}，Z：${z}，时间戳：${timestamp})
