无法确定任务 ':app:mergeDebugAssets' 的依赖关系

Question

当我在我的项目上运行 react-native run-android 时，我收到了 gradle 的构建错误。我已经用 npm uninstall --save react-native-ftp 卸载了 react-native-ftp，删除了 node_modules 的依赖，清除了 ./gradle 缓存文件。但是错误不断..

在我的环境窗口中，这个项目正常工作。

怎么回事？

Answer 1

步骤1：检查您的所有“ SDK Platforms ”和“ SDK Tools”是否已安装并更新”

步骤2：在android文件夹中创建“ local.properties ”文件 并粘贴以下内容

sdk.dir = /Users/USERNAME/Library/Android/sdk

这应该可以解决您的问题

Answer 2

转到您的项目级别 android 目录并运行./gradlew clean 如果问题仍然存在，请删除 node_modules 文件夹，npm install 或者您可以手动执行此操作： npm list然后解决所有UNMET DEPENDENCY问题
