react-native - 评估项目 ':app'时发生问题。可能是build.gradle问题

Question

我不断收到此错误:

A problem occurred configuring project ':app'.

每当我做react-native run-android时。我的怀疑是我在两个build.gradle之一中搞砸了

错误日志:(cmd)

FAILURE: Build completed with 2 failures.

1: Task failed with an exception.
-----------
* Where: Build file 'D:\Programs\reactnative\tokobangun\android\app\build.gradle' line:
103

* What went wrong: A problem occurred evaluating project ':app'.
Could not find method android() for arguments [build_52alt8ebvpuajag0a3orrbaix$_run_closure1@36f24a11] on project
':app' of type org.gradle.api.Project.

2: Task failed with an exception.
-----------
* What went wrong: A problem occurred configuring project ':app'.
Failed to notify project evaluation listener.
Could not get unknown property 'android' for project ':app' of type org.gradle.api.Project.
Could not get unknown property 'android' for project ':app' of type org.gradle.api.Project.

我试过了:

react-native run-android

gradlew清洁

两者都给我相同的结果。

我确实认为我在某个地方搞砸了android / build.gradle，并且尝试将其恢复为没有错误但无济于事的状态。有任何想法吗？

哦，如果您发现我的问题格式不够，请告诉我，我将尽我所能进行调整。在此先感谢。

在android / build.gradle中，将classpath(“com.android.tools.build:gradle:3.4.0”)更改为classpath'com.android.tools.build:gradle:3.3.0'，然后重试
