Angular 2应用程序在Chrome中运行,但不是IE 11

问题描述:

试图开始开发角度2应用程序。在YouTube上找到一个视频并与之一起运行。它工作得很好,但只在Chrome中。当我运行在IE 11的同一个应用程序,我得到以下错误:Angular 2应用程序在Chrome中运行,但不是IE 11

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 

所以我去谷歌找到一个解决方案。我了解到IE 11不支持es6,所以我需要将我的tsconfig.json中的目标框架从es6更改为es5。很明显,我的应用程序并不高兴,它会沿着以下方向返回各种错误:

"Build:Cannot find name 'Map'" and "Build:Cannot find name 'Set'". 

再次,关闭谷歌。我了解到,这两个对象现在完全不同于es5和es6,许多人提出了一些垫片。因此,我在我的package.json中添加了一个垫片,恢复软件包,并在我的主页面中引用它。我尝试再次建设,但我没有成功。

我质疑这些垫片是否确实在工作,但我不知道如何让他们“工作”。谢谢你的帮助。这是所有相关的代码。如果你需要更多,请让我知道。

我不知道这是什么意思。你能简化它吗?我假设我需要改变我的package.json中的东西,但我不确定是什么。 – champ8686

有一堆解决方案。只需花一些时间,尝试其中的一些......您可以在主文件中添加'/// ',或者尝试为' @ types/es6-shim' in your package.json' –

改变了我的package.json到:

{"compilerOptions": { 
"lib": [ "es5", "dom", "es6", "dom.iterable", "scripthost" ], 
"noLib": false, 
"target": "es5", 
"module": "commonjs", 
"moduleResolution": "node", 
"sourceMap": true, 
"emitDecoratorMetadata": true, 
"experimentalDecorators": true, 
"removeComments": false, 
"noImplicitAny": true, 
"types": ["node"]}, 
"exclude": [ 
"node_modules" 
] 

此外,一定要这两个参考加入到您的index.html。

<script src="node_modules/es5-shim/es5-shim.js"></script> 
<script src="node_modules/es6-shim/es6-shim.js"></script>
