在某些情况下，我刚刚开始浏览此处找到的 Ahead-of-time 编译食谱，尽管我不相信我的错误与它直接相关：https ://angular.io/guide/aot-compiler
我正在使用 Visual Studio 2015 并将我的 Angular 2 项目更新到新发布的 2.4 并且一切都构建得很好。但是，我随后更改了我的 tsconfig.json 文件以添加"lib": [ "es2015", "dom" ]到我的 compilerOptions。该文件现在如下所示：
{
"compilerOptions": {
"target": "es5",
"module": "commonjs",
"moduleResolution": "node",
"sourceMap": true,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"lib": [ "es2015", "dom" ],
"removeComments": false,
"noImplicitAny": true,
"outDir": "dist",
"suppressImplicitAnyIndexErrors": true
},
"compileOnSave": true
}
进行此更改后，我重新构建并收到以下构建错误：
构建：重复标识符“PropertyKey”。
我做了一些研究并决定"@types/core-js": "^0.9.34"从我的 package.json 文件中删除，这似乎已经解决了该错误，但我现在有以下新错误的几个实例：
构建：找不到名称“设置”
构建：找不到名称“承诺”
构建：找不到名称“地图”
这是我的完整 package.json 文件：

为了保持更新新版本，我几乎一直在此处复制示例 package.json 文件的依赖项部分：https ://angular.io/guide/quickstart
该链接适用于 JavaScript 版本，因为这是我能找到的唯一一个，但我实际上使用的是 TypeScript 2.1.4。正因为如此，我可能有这个文件的某些部分已经过时了。我只是不确定如何具体确定哪些部分。
