我有一个应用程序，它使用Babel将一些动态JS转换为es5兼容的JS，以便在IE浏览器中使用。
此设置在本地工作得很好，但是一旦部署到Azure，我在尝试调用
var babel = ReactEnvironment.Current.Babel;异常触发：
React.TinyIoC.TinyIoCResolutionException: Unable to resolve type: React.ReactEnvironment (Error getting vue module script) ---> React.TinyIoC.TinyIoCResolutionException: Unable to resolve type: React.JavaScriptEngineFactory ---> JavaScriptEngineSwitcher.Core.JsEngineLoadException: Failed to create instance of the ChakraCoreJsEngine. Most likely it happened, because the 'ChakraCore.dll' assembly or one of its dependencies was not found. Try to install the JavaScriptEngineSwitcher.ChakraCore.Native.win-x86 package via NuGet. In addition, you still need to install the Microsoft Visual C++ Redistributable for Visual Studio 2017 (https://www.visualstudio.com/downloads/#microsoft-visual-c-redistributable-for-visual-studio-2017). ---> System.DllNotFoundException: Unable to load DLL 'ChakraCore' or one of its dependencies: The specified module could not be found.

检查Azure
中的文件时，ChakraCore.dll似乎存在
我也尝试了这里的建议，卸载并重新安装所有相关的软件包https://github.com/reactjs/React.NET/issues/400

好吧，多亏了一些绝望的尝试和错误，这只是一个关于JavaScriptEngineSwitcher.ChakraCore.Native包添加对其他平台的支持的情况，我最初只有win-x64，但安装win-x86也对它进行了排序，并使其在Azure中工作。
这是我安装的包的最终结果，以使我的应用程序在Azure中成功工作：

我也遇到了这个问题，在阅读了其他答案后，我意识到这很可能是因为App Service中的配置设置为32位而不是64位。将配置更改为64位后，错误就消失了。我不确定其他人的情况，但对我来说，我没有改变代码，而是让我们的环境符合代码的要求。
1.在Azure门户中导航到Web应用程序
1.单击配置
1.单击顶部的“常规设置”选项卡。
1.在平台下，更改为64位。
1.单击保存（这样做将重新启动应用并应用设置）
