在某些情况下,我刚刚开始浏览此处找到的Ahead-of-time编译菜谱,但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并且所有内容都很好。然而,我改变了我的tsconfig.json文件,将"lib": [ "es2015", "dom" ]
添加到了我的compilerOptions。该文件现在看起来像这样:
{
"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
}
在此更改之后,我重新构建并获得以下构建错误:
构建:重复标识符' PropertyKey'。
我做了一些研究并决定从我的package.json文件中删除"@types/core-js": "^0.9.34"
,这似乎已经解决了这个错误,但我现在有几个以下新错误的实例:
构建:找不到名称'设置'
构建:找不到名字'承诺'
构建:找不到名称'地图'
这是我的完整package.json文件:

为了不断更新新版本,我在这里复制了示例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链接,但我实际上使用的是TypeScript 2.1.4。因此,我可能有这个文件的某些部分已经过时了。我不知道如何具体确定哪些部分。
答案 0 :(得分:0)
我不熟悉Visual Studio设置(intellij用户)。但也许吧 尝试使用。 “lib”:[“es6”,“dom”],或者可能删除“lib”:[ “es20125”,“dom”],完全尝试使用core-js @types。看着 我在这里回答如何使用core-js。
相关答案:
Angular 2 can't find Promise,Map,Set and Iterator
Cannot find name 'Promise'
此错误让我误以为您缺少ES6的类型定义。
Promise,Map和Set是es6规范。
您应该使用ES6 pollyfill库。
