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 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。 但是错误连续..

在我的环境 windows 这个项目工作正常。

发生了什么事？

Answer 1

Go to your project level android directory and run ./gradlew clean If the problem persists, delete node_modules folder and npm install or you can do this manually: npm list and then resolve all UNMET DEPENDENCY issues

Answer 2

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

Step2：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
