Question

我对react-native非常陌生，并且正在尝试通过阅读文档here在react-native中运行我的第一个应用程序。我将我的应用命名为rdvTemp。在react-native run-android中运行命令watchman/rdvTemp时，出现此错误：

我知道这意味着安装有问题，但是应该没有错，因为我一直在关注所有事情。我已经安装了Java和Android Studio，安装了Node，对本地CLI和Watchman做出了反应。 Java和Android Studio都是最新的。请告诉我我在做什么错或应该做什么。在其他地方，我无法获得任何帮助。谢谢...

第1步：

通过在.grade/dist内找到zip文件，确保已正确安装gradle。

第2步

yourProjectAppDir/android/gradle/wrapper/gradle-wrapper.properties文件中的

将distributionUrl更改为https\://services.gradle.org/distributions/gradle-YOUR_LOCAL_VERSION-all.zip

如果你有无法锁定任务历史记录缓存（APP_NAME\android\.gradle\YOUR_LOCAL_VERSION\taskHistory），因为此过程已将其锁定。

您可能需要通过删除.gradle \ caches文件夹来清除缓存
