仅限React Native Release APK Android崩溃

Question

我的apk调试正常！

建立APK版本行之有效！

当我将设备安装到设备时崩溃并从以下问题开始：

亚行日志猫

E AndroidRuntime: Process: br.com.missionbrasil, PID: 10382
E AndroidRuntime: java.lang.RuntimeException: com.facebook.react.devsupport.JSException: Strict mode does not allow function declarations in a lexically nested statement. (index.android.bundle:4)
E AndroidRuntime:   at com.facebook.react.bridge.DefaultNativeModuleCallExceptionHandler.handleException(DefaultNativeModuleCallExceptionHandler.java:24)
E AndroidRuntime:   at com.facebook.react.devsupport.DisabledDevSupportManager.handleException(DisabledDevSupportManager.java:172)
E AndroidRuntime:   ... 7 more
W ActivityManager:   Force finishing activity br.com.missionbrasil/.MainActivity

我将所有条件=> { vars && (<View></View>) } to { vars ?: }

清洁./gradlew 100次...

package.json

    "@expo/react-native-fade-in-image": "^1.1.1",

    "babel-preset-react-native": "4.0.0",
    "jest": "21.2.1"

  "jest": {

  }

有人遇到同样的问题吗？

问候。

Answer 1

SyntaxError：严格模式不允许在词法嵌套语句中进行函数声明

请按照下面概述的步骤搜索并替换node_modules文件夹中的3个字符串：

步骤1 | NativeModules.js

• 转至： /node_modules/react-native/Libraries/BatchedBridge/BatchedBridgedModules/NativeModules.js
• 查找： function normalizePrefix(moduleName: string)
• 替换为： const normalizePrefix = function(moduleName: string)

步骤2 | UIManager.js

• 转至： /node_modules/react-native/Libraries/Utilities/UIManager.js
• 查找： function normalizePrefix(moduleName: string)
• 替换为： const normalizePrefix = function(moduleName: string)

步骤3 | InitializeJavascriptAppEngine.js

• 转至： node_modules\\react-native\\Libraries\\JavaScriptAppEngine\\Initialization\\InitializeJavaScriptAppEngine.js
• 查找： function handleError(e, isFatal)
• 替换为： var handleError = function(e, isFatal)

步骤4 | npm start--重置缓存

替换所有字符串后，运行npm start -- --reset-cache ，它现在应该可以工作了

Answer 2

我只是清理.babelrc中的所有插件，并且像魅力一样工作。

像这样：

{
  "presets": [
    "react-native"
  ]
}

我的问题的原因是=>“ transform-es2015-modules-commonjs”

感谢克雷格的帮助！
