【问题描述】：

所以我刚刚使用 '$ npx react-native init tracking' 创建了一个反应原生应用程序'tracks'，当我尝试运行命令 '$ npx react-native run- android'，它显示以下错误。我尝试将类路径 gradle 版本（默认 4.2.2）更改为许多其他版本，但没有用。 几天来我一直无法绕过它。请帮忙**

【参考方案1】：

我能提供的最佳帮助是，如果您的 build.gradle 文件不应用 android 插件，它将无法解析导入“com.android.build.OutputFile”。

您使用“com.android.build.OutputFile”的 gradle 文件需要这一行：

apply plugin: 'com.android.application'

此行只应添加到应用模块级构建文件中。

不幸的是，我不太了解本地反应。我只是从我在正常项目中遇到这个问题时如何解决这个问题来回答。
