错误:传感器的本机模块不可用。react-native链接是否成功运行？

Question

我是React Native的新手，你能帮我吗？我刚刚安装了react-native- sensors (Yarn add --保存react-native-sensors)，然后我导入了我的项目(从“react-native -sensors”导入{ Accelerometer }；)，但我收到了这条信息："Native Modules for sensors not available. Did -native link run？“

我运行了命令"react-native link react-native-sensors"，但错误仍然存在=(

我使用的是"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",
"test": "jest"
},
"dependencies": {
"lodash": "^4.17.11",
"react": "16.6.1",
"react-native": "0.57.7",
"react-native-gesture-handler": "^1.0.10",
"react-native-sensors": "^5.1.5",
"react-navigation": "^3.0.8",
"rxjs": "^6.3.3"
},
"devDependencies": {
"babel-jest": "23.6.0",
"jest": "23.6.0",
"metro-react-native-babel-preset": "0.48.5",
"react-test-renderer": "16.6.1"
},
"jest": {
"preset": "react-native"
}
}

谢谢！=)

Answer 1

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

你是在iOS上测试吗？如果您是在iOS上测试，则需要添加以下内容。

选项:使用CocoaPods (仅限iOS)

将以下内容添加到您的Podfile中并运行$ pod install:

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

检查您的AVD的传感器功能，并尝试使用真实的设备。对于给定的依赖版本，它工作得很好：- "react-native-sensors": "^5.1.8"。以下是一小段代码：-timestamp X：${ x }，Y:${y}，Z:${z}，时间戳：${import { accelerometer, gyroscope, setUpdateIntervalForType, SensorTypes } from "react-native-sensors"; accelerometer.subscribe(({ x, y, z, timestamp }) => { console.log(} )
