我负责维护使用React Native开发的应用程序两年。安卓项目的目标设置为API 30，客户端希望将其更新为API 31。我原以为在格雷德尔很容易改变的事情，结果却让人头疼。
我不知道我已经尝试了多少东西(更新react native、更新gradle、安装JDK11…(，但我最终放弃了更改，并再次从存储库中克隆了所有代码。
以下是我现在确定已经完成的步骤：
- 安装JDK11(以前已安装(
- 从存储库中克隆React Native项目
- 运行命令
npm install - 将Gradle更新到7.3.3版本(我通过使用Android Studio打开Android项目来完成这一操作(
这些是packages.json:中包的版本
"dependencies": {
...
"react": "17.0.2",
"react-native": "0.67.2",
...
},
"devDependencies": {
"@babel/core": "7.12.13",
"@babel/runtime": "7.12.13",
"@react-native-community/eslint-config": "1.1.0",
"babel-jest": "25.5.1",
"eslint": "6.8.0",
"jest": "25.5.4",
"metro-react-native-babel-preset": "0.59.0",
"react-test-renderer": "16.13.1"
},
此时，我可以使用react-native run-android命令运行应用程序，但不加载图像。当然，由于我已经从头开始克隆了这个项目，所以我必须创建资源。为此，我执行了这个命令，我在过去使用过很多次：
react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/ app/src/main/res
但我得到了这个错误：
warn Package react-native-vector-icons contains invalid configuration: "dependency.assets" is not allowed. Please verify it's properly linked using "react-native config" command and contact the package maintainers about this.

有一件事我不明白：安装的react本机版本是"0.67.2〃；，但是当我试图创建资源时；欢迎使用Metro v0.72.3"；。我不知道这是否有道理。
文件C:Users{myusername}AppDataRoamingnpmnode_modulesreact-nativenode_modulesmetro-runtimesrcmodulesempty-module.js退出。
你知道我为什么会犯这个错误吗？
cli似乎已损坏。我用--force:解决了安装它的问题
npm install -g react-native-cli @react-native-community/cli --force
