Question

我为Windows上的本机反应进行了必要的设置。然后，我使用命令“ npx react-native init projectname”创建了我的项目。然后，我使用“ npx react-native run-android”命令运行了项目，但出现以下错误。

Answer 1

首先，您必须安装@ react-native-community / cli-platform-android的最新版本

npm i @react-native-community/cli-platform-android

然后转到android目录并通过以下命令清理gradlew

cd android && gradlew clean

返回您的主目录并运行应用程序

cd.. && react-native run-android
