Question

我的apk-debug工作正常！

Build apk-release工作正常！

当我安装到设备时，应用程序崩溃并从此问题开始：

adb logcat

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

我改变所有条件=＆gt; { vars && (<View></View>) } to { vars ?: }

清洁./gradlew 100次......

的package.json

"dependencies": {
    "@expo/react-native-fade-in-image": "^1.1.1",
    "@expo/react-native-touchable-native-feedback-safe": "^1.1.2",
    "autobind-decorator": "^1.3.4",

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

任何人都有同样的问题吗？

问候。

Answer 1

SyntaxError：严格模式不允许在词法嵌套语句中使用函数声明

按照下面列出的步骤搜索并替换node_modules文件夹中的3个字符串：

第1步| NativeModules.js

转到：/node_modules/react-native/Libraries/BatchedBridge/BatchedBridgedModules/NativeModules.js

发现：function normalizePrefix(moduleName: string)

替换为：const normalizePrefix = function(moduleName: string)


第2步| UIManager.js

转到：/node_modules/react-native/Libraries/Utilities/UIManager.js

发现：function normalizePrefix(moduleName: string)

替换为：const normalizePrefix = function(moduleName: string)


第3步| InitializeJavascriptAppEngine.js

转到：node_modules\react-native\Libraries\JavaScriptAppEngine\Initialization\InitializeJavaScriptAppEngine.js

发现：function handleError(e, isFatal)

替换为：var handleError = function(e, isFatal)


第4步| npm start - --reset-cache

替换所有字符串后运行npm start -- --reset-cache，它现在应该可以正常工作

Answer 2

我只是清理.babelrc中的所有插件，就像魅力一样。

像这样：

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

我的问题的原因是=＆gt; ＆＃34;变换ES2015模块-CommonJS的＆＃34;
