react native 运行 android 有错误。解决错误后无法更改配置 ':packagename:androidApis' 的依赖项

Question

我有一个 React Native 项目，其中包含许多库，例如 React Native Fetch Blob、React Native Camera 等。

对于 运行 项目，我克隆了我的存储库并安装了节点模块，因此 运行 react-native 运行 命令遇到以下错误：

经过几个小时的搜索和尝试，我无法解决问题。之后，我从项目中删除了 React Native Fetch Blob 并再次 运行 android 所以 React Native Camera

遇到了新的错误

我认为这个错误在我的 android 配置中出现并且不需要 React Native 库。

/**

谁能帮我解决这个问题？？？

Answer 1

这对我来说是一个令人困惑的问题。为了解决这个问题，我做了一些步骤：

1) 如下更改 ext 变量：

ext {
        buildToolsVersion = "28.0.3"
        minSdkVersion = 16
        compileSdkVersion = 28
        targetSdkVersion = 28
        supportLibVersion = "27.1.1"
    }

2) 增加react native版本到 "react-native": "0.59.8",

3) 在 gradle.properties 文件中启用 androidX:

android.useAndroidX=true
android.enableJetifier=true

4) 在我的 java 和清单文件中将 appcompat 库导入更改为 AndroidX 库。例如，我是这样改的：

<provider android:name="android.support.v4.content.FileProvider" ... 

对此：

<provider android:name="androidx.core.content.FileProvider" ... 

5) 安装 jetifier

6) 运行 npx jetifier

7) 运行 npx react-native run-android 到 运行 android 项目

8) 享受你可爱的应用程序
