React Native 构建无法评估“android”

问题描述 投票：0回答：1

我正在尝试 

build
在 Android Studio (Koala [v 2024]) 上使用 React Native (
$ npx react-native init AnAppName
) 创建的应用程序。

我遇到了一些问题，因为我的 Java 和 Gradle 需要更新和添加路径。更新Java和Gradle后，我刚刚删除了以前的项目并开始了一个新的项目。这个新应用程序也没有修改任何代码。我所做的就是执行

$ npx react-native init AnAppName
，在Android Studio（Koala）中打开它，然后执行
$ npx react-native run-android
。我已正确连接设备进行测试并创建了 Android 模拟器。

向终端（Android Studio Powershell 终端）抛出的错误代码是：

    ERROR: autolinkLibrariesFromCommand: process cmd /c npx @react-native-community/cli config exited with error code: 1
    
    FAILURE: Build failed with an exception.
    
    * Where:
    Settings file 'C:\Users\USER NAME\reactNativeProjects\aaaandanotherproject\android\settings.gradle' line: 3
    
    * What went wrong:
    A problem occurred evaluating settings 'android'.
    > ERROR: autolinkLibrariesFromCommand: process cmd /c npx @react-native-community/cli config exited with error code: 1

提到的 settings.gradle 文件（自初始化应用程序以来未经编辑）是：

路径：项目名称/android/settings.gradle 文件开始：settings.gradle

    pluginManagement { includeBuild("../node_modules/@react-native/gradle-plugin") }
    plugins { id("com.facebook.react.settings") }
    extensions.configure(com.facebook.react.ReactSettingsExtension){ ex ->     ex.autolinkLibrariesFromCommand() }
    rootProject.name = 'aaaandanotherproject'
    include ':app'
    includeBuild('../node_modules/@react-native/gradle-plugin')

文件结束：settings.gradle

我尝试从

settings.gradle
行中删除第三行：

    extensions.configure(com.facebook.react.ReactSettingsExtension){ ex ->     ex.autolinkLibrariesFromCommand() }

但这只是创建了一个错误，表示 

':app'
未初始化。

包含 autolinkLibrariesFromCommand 函数的 

ReactSettingsExtension.kt

自动创建且尚未被我修改的package.json文件是：

  "private": true,
  "scripts": {

    "typescript": "5.0.4"
  },
  "engines": {
    "node": ">=18"
  }
}

文件结束：package.json

我该怎么办？

react-native

从未遇到过此类问题。一个可能的解决方案是检查 package.json 文件并检查 @react-native-community/cli 和react-native 包之间的兼容性

"dependencies": {
    ...

    "@react-native-community/cli": "^5.0.1", --> you have to check this version 
    "react-native": "0.63.3"

    ...
}
