任务“:app:compileDebugKotlin”执行失败。反应本机更新

Question

我刚刚按照 React Native 升级助手的说明将 React Native 从 0.71.11 更新到 0.73.7。当我尝试运行“yarn android”时，出现此错误

错误：android/app/src/main/java/com/useapp/MainApplication.kt:18:41“getPackages”的返回类型不是重写成员“protected/protected 和 package”的返回类型的子类型/ Abstract fun getPackages(): (MutableList..kotlin.collections.List?) 在 com.facebook.react.defaults.DefaultReactNativeHost' 中定义 e: /android/app/src/main/java/com/useapp/MainApplication.kt:19:24 类型不匹配：推断类型是 ArrayList！但列表是预期的 e: android/app/src/main/java/com/useapp/MainApplication.kt:35:13 未解析的参考：ReactHost

失败：构建失败并出现异常。

• 出了什么问题： 任务“:app:compileDebugKotlin”执行失败。

执行 org.jetbrains.kotlin.compilerRunner.GradleCompilerRunnerWithWorkers$GradleKotlinCompilerWorkAction 时发生故障 编译错误。查看日志了解更多详情

            // If you opted-in for the New Architecture, we load the native entry point for this app.
            ReactHost.load() // This seems to be a custom function, make sure it's defined correctly
        }
        // ReactNativeFlipper.initializeFlipper(this, reactNativeHost.reactInstanceManager)
        // This line is commented out as ReactNativeFlipper seems unresolved in your code
    }
}

MainActivity.kt

package xxx.xxx
import com.facebook.react.ReactActivity
import com.facebook.react.ReactActivityDelegate
import com.facebook.react.defaults.DefaultReactActivityDelegate
import android.os.Bundle

class MainActivity : ReactActivity() {

    /**
     * Returns the name of the main component registered from JavaScript. This is used to schedule
     * rendering of the component.
     */
    override fun getMainComponentName(): String = "xxx"

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
    }

    /**
     * Returns the instance of the [ReactActivityDelegate]. We use [DefaultReactActivityDelegate]
     * which allows you to enable New Architecture with a single boolean flags [fabricEnabled]
     */
    override fun createReactActivityDelegate(): ReactActivityDelegate =
        DefaultReactActivityDelegate(this, "useapp") // Provide mainComponentName as a string
}

我试图弄乱这两个文件，但到目前为止还没有成功。

只需删除

导入java.util.List

在您的 MainApplication.kt 中，然后重试。
