尝试开发angular 2应用程序。在YouTube上找到了一段视频并与之一起运行。它工作得很好,但只有在铬。当我在IE 11中运行相同的应用程序时,我得到以下错误:
Error: (SystemJS) Syntax error
SyntaxError: Syntax error
at Anonymous function (eval code:4:1)
at Anonymous function (eval code:1:31)
Evaluating http://localhost:52688/app/app.module.js
Evaluating http://localhost:52688/app/main.js
Error loading http://localhost:52688/app/main.js
所以我去谷歌寻找解决方案。我了解到IE 11不支持es6,所以我需要在tsconfig中更改我的目标框架。从es6到es5的json。显然,我的应用程序对此并不满意,它返回了以下各种错误:
"Build:Cannot find name 'Map'" and "Build:Cannot find name 'Set'".
再一次,转到谷歌。我了解到这两个对象现在在es5和es6之间完全不同,许多人建议使用一些垫片。所以我在包中添加了一个垫片。json,还原包,并在我的主页中引用它。我再次尝试建造,但没有成功。
我怀疑这些垫片是否真的起作用了,但我不知道如何让它们“起作用”。谢谢你的帮助。以下是所有相关代码。如果你需要更多,请告诉我。
