在 Windows 10 上没有 android studio 环境的 React Native

Question

i'm new to React Native, so i've followed tutorial; i've created the app from create-react-native-app , putting some functionality and tested with expo and it worked well. But now i'm passing to react native with native code by using npm run eject and choosed the bare react-native but not the expo, the ejection was successful. But when i run the command react-native run-android i got this error: enter image description here

I'm not using android studio but only the sdk manager, already installed jdk and i've installed android package for android 5 to 9; the environement path is:

user variable:

JAVA_HOME: C:\\Program Files\\Java\\jdk1.8.0_131

ANDROID_HOME: C:\\Users\\Necrometal XD\\AppData\\Local\\Android\\android-sdk

Path: C:\\Users\\Necrometal XD\\AppData\\Local\\Android\\android-sdk\\platform-tools; C:\\Users\\Necrometal XD\\AppData\\Local\\Android\\android-sdk\\tools; C:\\Program Files\\Java\\jdk1.8.0_131 C:\\Users\\Necrometal XD\\AppData\\Local\\Android\\android-sdk\\platform-tools; C:\\Users\\Necrometal XD\\AppData\\Local\\Android\\android-sdk\\tools; C:\\Program Files\\Java\\jdk1.8.0_131

system variable:

ANDROID_HOME: C:\\Users\\Necrometal XD\\AppData\\Local\\Android\\android-sdk

ANDROID_SDK_HOME: C:\\Users\\Necrometal XD\\AppData\\Local\\Android\\android-sdk

Path: C:\\Users\\Necrometal XD\\AppData\\Local\\Android\\android-sdk\\platform-tools; C:\\Users\\Necrometal XD\\AppData\\Local\\Android\\android-sdk\\tools; C:\\Users\\Necrometal XD\\AppData\\Local\\Android\\android-sdk\\platform-tools; C:\\Users\\Necrometal XD\\AppData\\Local\\Android\\android-sdk\\tools;

my device is connected, i've already checked with adb devices

result:

List of devices attached

我修好了 :) 我用的是小米8，更新版本后没看到我的开发者模式被禁用，所以只需要启用调试模式并通过usb安装
