我最近想创建一个带有相机的react-native应用程序，并开始使用react-native-camera所以我就这样做了：
$ react-native init testApp2
$ npm install --save react-native-camera
$ react-native link react-native-camera
$ react-native run-android
在最后一行之后，我得到了奇怪的输出(下图((我的电脑上安装了 Android 工作室，当我去构建 apk 时，安卓工作室会创建确切的错误(

Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:

我已经尝试了所有可能的方法与Android工作室一起玩来修复此错误，但我真的很累，不知道下一步该怎么做。
这是我package.json：
{
"name": "testApp2",
"version": "0.0.1",
"private": true,
"scripts": {
"start": "node node_modules/react-native/local-cli/cli.js start",
"test": "jest"
},
"dependencies": {
"react": "16.3.1",
"react-native": "0.55.4",
"react-native-camera": "^1.1.3"
},
"devDependencies": {
"babel-jest": "22.4.4",
"babel-preset-react-native": "4.0.0",
"jest": "22.4.4",
"react-test-renderer": "16.3.1"
},
"jest": {
"preset": "react-native"
}
}
如果你知道这个请求有什么问题，告诉我，我开始变得非常疯狂......
因为我不知道如何将我的所有代码放在这里，所以我刚刚将其上传到 GitHub 上，这里是它的链接。
尝试启用 multiDex
在app/build.gradle 中：
android {
defaultConfig {
multiDexEnabled true
}
}
