React Native：錯誤無法安裝應用程序。 確保您已設置 Android 開發環境

Question

我是 React Native 的新手，我嘗試從這個鏈接安裝 BackEndless： Patch for using Backendless JS-SDK inside React Native App。

但我意識到這是一個錯誤，無論如何，在安裝 Backendless 之后，android 應用程序不再工作，我遇到了這個問題：

npm 運行 android

awesomeproject8@0.0.1 android react-native 運行 android

信息 運行 jetifier 將庫遷移到 AndroidX。 您可以使用“--no-jetifier”標志禁用它。 （節點：7797）警告：訪問循環依賴中模塊導出的不存在的屬性“padLevels”（使用node --trace-warnings...顯示警告的創建位置）Jetifier 找到了 1065 個要轉發的文件-噴射。 使用 8 個工人...信息 JS 服務器已經在運行。 信息正在啟動模擬器...錯誤無法啟動模擬器。 原因：模擬器在啟動前退出。警告請手動啟動模擬器或連接設備。 否則應用程序可能無法啟動。 信息正在安裝應用程序...

那是我的 build.gradle 文件：

/**
 * The react.gradle file registers a task for each build variant (e.g. bundleDebugJsAndAssets
 * and bundleReleaseJsAndAssets).
 * These basically call `react-native bundle` with the correct arguments during the Android build
 * cycle. By default, bundleDebugJsAndAssets is skipped, as in debug/dev mode we prefer to load the
 * bundle directly from the development server. Below you can see all the possible configurations
 * and their defaults. If you decide to add a configuration block, make sure to add it before the
 * `apply from: "../../node_modules/react-native/react.gradle"` line.

 *   bundleAssetName: "index.android.bundle",

 *   // the entry file for bundle generation. If none specified and
 *   // "index.android.js" exists, it will be used. Otherwise "index.js" is
 *   // default. Can be overridden with ENTRY_FILE environment variable.
 *   entryFile: "index.android.js",
 *
 *   // https://reactnative.dev/docs/performance#enable-the-ram-format

 *   // See http://tools.android.com/tech-docs/new-build-system/user-guide#TOC-Build-Variants
 *   // The configuration property can be in the following formats
 *   //         'bundleIn${productFlavor}${buildType}'

 *   // date; if you have any other folders that you want to ignore for performance reasons (gradle

Go 到您的項目級別 android 目錄並運行./gradlew clean 如果問題仍然存在，請刪除 node_modules 文件夾和 npm 安裝，或者您可以手動執行此操作：npm 列表，然后解決所有 UNMET DEPENDENCY 問題。
