Answer 1

可能是因为上面提到的JDK版本。 你可以通过运行 react native doctor 来验证

npx @react-native-community/cli doctor

Answer 2

安装 JDK 1.8 并设置 $JAVA_HOME 环境变量并尝试再次运行该应用程序。

错误是由于JDK版本较低或未安装JDK。

Answer 3

您的问题只需按照以下步骤即可解决： 将 node_modules 依赖项 jetify / 转换为 AndroidX 想象一下，你有一个 react-native 项目。您的库依赖项之一转换为 AndroidX。您需要使用新版本。

所以现在您需要将您的应用程序转换为 AndroidX，但是您的许多 react-native 库都提供了本机 Java 代码并且尚未更新。这是怎么做到的？

首先，使用 Android Studio 的重构工具将您的应用重新转换：Android 开发者文档 npm install --save-dev jetifier npx 喷射 npx react-native run-android （您的应用程序应该正确编译和工作） 在你的 package.json 的 postinstall 目标中调用 npx jetify run （任何时候你的依赖更新你都必须再次jetify
