生成签名 APK 时出错

Question

我正在尝试捆绑一个 React-Native Android 应用程序。我已将主应用程序复制到“测试”文件夹以执行此操作，并且我正在按照此处的说明进行操作：

Guide to Generate Signed APK

我在我跑步的地方：

$ cd android && ./gradlew assembleRelease

在出现错误之前一切似乎都很顺利。使用 stacktrace 运行给了我：

构建失败

有人见过这个吗？任何帮助将不胜感激！

Answer 1

对我有用的是，我删除了我的 node_modules 文件夹并做了

npm install

cd android

./gradlew assembleRelease

Answer 2

我没有遇到这个问题，但如果 curl 请求成功，听起来你的 build.gradle 配置错误。我使用“默认”反应原生项目提供的react.gradle 文件。我的 build.gradle 配置如下所示（注意：它使用了很多默认值，但我喜欢明确说明这些选项）。生成的打包程序命令如下所示：

    react-native bundle --platform android --dev true --entry-file react/index.android.js --bundle-output mobile/android/app/build/intermediates/assets/debug/index.android.bundle --assets dest mobile/android/app/build/intermediates/res/merged/debug

如果您的构建步骤到了这个阶段并失败了，剩下的可能性是您的节点环境在某种程度上配置错误。

    // React Native build configuration
    project.ext.react = [
            // the name of the generated asset file containing your JS bundle
            bundleAssetName    : "index.android.bundle",
            // the entry file for bundle generation
            entryFile          : "react/index.android.js",
            // whether to bundle JS and assets in debug mode

            // When building from Android Studio bundleInDebug evalutes to false while using gradlew
            // it overrides to true as it should. I don't 100% understand why that is, but luckily this
            // is the behavior I want to have.
            bundleInDebug      : true,
            // whether to bundle JS and assets in release mode
            bundleInRelease    : true,
            // the root of your project, i.e. where "package.json" lives
            root               : "../../",

            // were to put the JS bundle asset in debug mode
            jsBundleDirDebug   : "$buildDir/intermediates/assets/debug",
            // where to put the JS bundle asset in release mode
            jsBundleDirRelease : "$buildDir/intermediates/assets/release",

            // where to put drawable resources / React Native assets, e.g. the ones you use via
            // require('./image.png')), in debug mode
            resourcesDirDebug  : "$buildDir/intermediates/res/merged/debug",

            // were to put drawable resources / React Native assets, e.g. the ones you use via
            // require('./image.png')), in release mode
            resourcesDirRelease: "$buildDir/intermediates/res/merged/release",

            // b default the gradle tasks are skipped if none of the JS files or assets change; this means
            // that we don't look at files in android/ or ios/ to determine whether the tasks are up to
            // date; if you have any other folders that you want to ignore for performance reasons (gradle
            // indexes the entire tree), add them here. Alternatively, if you have JS files in android/
            // for example, you might want to remove it from here.
            inputExcludes      : []
    ]
    apply from: 'react.gradle'
