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。

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>

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' –
