有人可以告诉我解决方案这是我的代码？与本地服务器一起工作，当我转移到托管服务器时，会出现以下错误。

当我使用非产品标志时，它的工作正常，但我个人觉得要获得更好的性能因素，希望与产品环境一致。

Answer 1

由于它在您的PC上工作正常，这告诉我您部署应用程序的托管服务器上缺少您的PC上存在的某些库。 devDependency部分中的一些包显示为空字符串是什么？

此外，由于错误消息引用单字母变量e，我可以假设您执行了生成构建，其中uglify.js重命名了所有变量。因此，尝试在没有--prod选项的情况下进行构建，并将其部署在托管服务器上。它可能会给您一个更易读的错误消息。

错误：没有e的提供者！与prod标志（在本地服务器上正常工作）angular4
