构建失败:当我运行npm运行android时无法安装该应用程序

Question

我试图用reactnative构建一个移动应用程序，并在android仿真器上进行测试，但是当我使用npm运行android程序时，它就失败了。我尝试修改gradle.build文件(将sdk版本升级到31 ..)但什么都不管用。npm安装工作正常，没有任何漏洞。

这是命令的输出：

>react-native run-android

转到您的babel.config，并添加"plugins：‘react本机-恢复/插件’“。

您的babel.config.js文件应该如下所示

module.exports = {
  presets: ['module:metro-react-native-babel-preset'],
  plugins: ['react-native-reanimated/plugin'],
};

检查你的android/app/build.gradle，如果你有正确的配置，以应用反应-本机-矢量-图标。该配置应该如下所示：

project.ext.vectoricons = [
    iconFontNames: [ 'Ionicons.ttf' ] // Name of the font files you want to copy
]

apply from: "../../node_modules/react-native-vector-icons/fonts.gradle"

尝试清理您的项目:使用以下命令。一个接一个地运行(注意，如果使用纱线，可以更改npm安装，而可以使用纱线安装)

watchman watch-del-all
rm -rf yarn.lock package-lock.json node_modules
rm -rf android/app/build
rm ios/Pods ios/Podfile.lock 
rm -rf ~/Library/Developer/Xcode/DerivedData
npm install && cd ios && pod update && cd ..
npm start -- --reset-cache

在终端中使用以下命令运行项目：

npx react-native run-android ... for android 

npx react-native run-ios ... for ios

步骤1.在下面的路径'android\app\src\main\assets‘中创建一个文件夹“字体”。确保“字体”的“f”是小的。

第二步，复制'node_modules\react-native-vector-icons\Fonts‘中的所有文件，并在“android\src\main\\fonts”中通过它。

步骤3.从模拟器中删除现有的应用程序，然后再运行一次。
