FAILURE：构建失败并出现异常。 * 出了什么问题：任务 ':app:compileDebugKotlin' 执行失败

Question

我正在尝试为我的 React-native 项目生成 android 版本，但在编译过程中遇到此错误。我找不到问题的原因

我按照 Expo 文档中更新本机项目的步骤进行操作。因为我的项目需要从SDK49更新到SDK50。我正在使用裸工作流程项目模型

https://docs.expo.dev/bare/upgrade/?fromSdk=49&toSdk=50#androidbuildgradle

Answer 1

您可以使用以下步骤和命令清理并重建项目。

1. 从 android 文件夹中删除 .gradle 文件夹
2. 删除节点模块
3. 使用 npm i 命令安装节点模块
4. cd 安卓
5. ./gradlew 干净
6. npx react-native start --reset-cache
7. 运行项目

如果这些步骤对您不起作用，请在 android 的 build.gradle 文件中验证以下版本。如果不符合预期，则按照预期安装并再次执行上述 7 个步骤。

buildscript {
    ext {
        buildToolsVersion = "34.0.0"
        minSdkVersion = 33
        compileSdkVersion = 34
        targetSdkVersion = 34
        ndkVersion = "26.1.10909125"
        kotlinVersion = "1.9.22"
    }

希望对你有帮助。
