我有一个现有的 React 本机应用程序。我想创建另一个应用程序并在它们之间共享一些代码。\n我利用 MetroextraNodeModules将共享代码导入到任一应用程序中。\n在任一应用程序中，我希望能够执行以下操作：

// MyApp1/src\\navigation\\app.navigator.js\nimport { someUtilModule } from \'shared\';\n

不幸的是，当应用程序包加载到我的开发设备上时，它失败并显示：

error: Error: Unable to resolve module `shared` from `src\\navigation\\app.navigator.js`: shared could not be found within the project or in these directories:\n  C:\\path\\to\\my\\project\n\nIf you are sure the module exists, try these steps:\n 1. Clear watchman watches: watchman watch-del-all\n 2. Delete node_modules: rm -rf node_modules and run yarn install\n 3. Reset Metro\'s cache: yarn start --reset-cache\n 4. Remove the cache: rm -rf /tmp/metro-*\n    at ModuleResolver.resolveDependency …

我正在使用 Django 和 mongoengine。我有一个带有铭文列表的模型类，我想获取在该列表中具有 id 的文档。

classes = Classes.objects.filter(inscriptions__contains=request.data['inscription'])

我一直在使用 React Native 0.60.4 为 android 和 ios 开发一个应用程序，最近我发现将应用程序置于分屏或自由格式模式（因为它是屏幕上唯一的应用程序）有时会导致它崩溃。

我进一步玩了这个，发现我可以毫无问题地将应用程序启动到分屏或自由格式模式，但有时调整它的大小会导致它崩溃。下面是我在 Android Studio 中的调试器实例的输出，我正在努力理解：

我来自谷歌云平台，并且已经习惯于创建服务代理，本质上是用户帐户来授予我指定给非人类参与者的权限/访问权限，以便他们可以查看/修改资源/属性。我整个晚上都在探索 Azure，但找不到类似的东西。谁能建议我应该阅读的 Azure 服务或关键字，以便我弄清楚如何在 Azure 中实现类似的身份和访问？

随装 yarn install react-native-unimodules

说明中的下一步要求我编辑项目Podfile。此处显示了必要的添加。

这是我生成的Podfile

platform :ios, '10.0'
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'
