Javascript react本机生成错误：在项目'；上找不到参数[jscFlavor]的方法实现（）：app&x27；类型为org.gradle.api.Project

我一直在运行android模拟器

这是我在运行

react native run android

时遇到的错误：

安装应用程序失败时出错。确保你有安卓系统 开发环境设置： . 有关详细信息，请使用--verbose标志运行CLI。错误：命令失败： ./gradlew应用程序：installDebug-PreactNativeDevServerPort=8081

失败：生成失败，出现异常

• 其中：构建文件“/Users/yashatreya/Desktop/Realyze/Realyze/android/app/Build.gradle” 电话：209

• 出了什么问题：

评估项目“：app”时出现问题

在类型为“”的项目“：app”上找不到参数[org.webkit:android jsc:+]的方法实现（） org.gradle.api.Project

• 尝试：使用--stacktrace选项运行以获取堆栈跟踪。使用--info或--debug选项运行以获得更多日志输出。使用--scan运行以获得完整的洞察力

• 得到更多的帮助

这是我的
