应用程序上的react-native运行android时生成错误而没有更改

Question

我有一个React Native 0.61应用程序，该应用程序运行良好，但并非没有任何变化，我知道。这是react-native run-android时的错误：

FAILURE: Build failed with an exception.

我所做的是从头开始重建项目，并逐个添加每个模块。但是错误是完全相同的。该项目过去很好，并且已经从中生成了apk。我对这里可能发生的问题感到迷茫。这是package.json的依赖项：

"dependencies": {
    "@react-native-community/async-storage": "^1.6.2",
    "moment": "^2.24.0",
    "react": "16.9.0",

您好，请添加最新的@ react-native-community / cli-platform-android：“ ^ 3.0.3”并删除以前的节点模块，然后在我的情况下运行npm install来解决此问题。 请检查以下图片。因为新的react native需要本地安装的react native cli，而不是全局的react native cli。
