AS 中的 Gradle 同步失败：找不到 com.android.tools.build:gradle:4.0.0

Question

我是 Android 工作室的新手，我正在使用 react-native 构建我的应用程序。当我打开 android studio 时，Gradle build 开始了，我得到了这个错误

Could not find com.android.tools.build:gradle:4.0.0.
Searched in the following locations:
  - https://jcenter.bintray.com/com/android/tools/build/gradle/4.0.0/gradle-4.0.0.pom
If the artifact you are trying to retrieve can be found in the repository but without metadata in 'Maven POM' format, you need to adjust the 'metadataSources { ... }' of the repository declaration.

我搜索了堆栈溢出问题，我尝试了很多解决方案但对我没有任何帮助， 我已经尝试过的 gradlew clean ， gradlew build --refresh-dependencies ， gradlew cleanBuildCache 但这些所有命令都显示相同的错误日志。 然后我删除了android/.gradle 和android/.idea 文件夹以及app.iml 文件（但仍然是同样的错误） 我也尝试过 react-native 项目目录中的npm cache clean --force 我也试过File> invalidate Caches /Restart。 android/build.gradle文件

好吧，我正在回答我自己的问题。如果您在这里并且已经尝试过我上面尝试过的方法，那么您可以试一试，尝试删除node-modules 文件夹并再次运行npm install，它确实对我有用。
