angular2:找不到模块"@ angular/core" [英] angular2: Cannot find module '@angular/core'

问题描述

我按照angular2 快速启动创建了我的项目，一切正常但是我的"tsc -w"命令行不断告诉我:

I followed the angular2 quick start to create my project and everything works fine but my "tsc -w" command line keeps on telling me:

app/components/company/company.ts(1,36): error TS2307: Cannot find module '@angular/core'.
app/components/company/company.ts(5,22): error TS2307: Cannot find module '@angular/router'.
app/components/mission/mission.ts(1,36): error TS2307: Cannot find module '@angular/core'.
app/components/mission/mission.ts(3,22): error TS2307: Cannot find module '@angular/router'.

还有很多其他类似的内容.但是，所有内容都可以成功编译，并且我的应用程序可以正常工作，但是将所有这些警告/错误作为真正的错误在其中途丢失会很烦人.

And there is plenty of other line like this. However, everything is compiled successfully and my application works fine, but it's quite annoying to have all these warnings/errors as real errors something get lost in the middle of them.

我正在使用Angular2 rc1，TypeScript 1.8.10，WebStorm EAP(虽然我没有使用WebStorm TypeScript编译系统，但我依靠的是带有"tsc -w"命令行的开放式终端).

I'm using Angular2 rc1, TypeScript 1.8.10, WebStorm EAP (altough I'm not using the WebStorm TypeScript compilation system, I'm relying on an open terminal with "tsc -w" command line).

我在SO上检查了与此相关的其他问题，但没有发现任何真正对我有帮助的东西.

I checked other question related to that on SO, but I didn't find anything that really helped me.

更新

这是我的tsconfig.json文件:

Here is my tsconfig.json file:

{
  "compilerOptions": {
    "target": "es5",
    "sourceMap": true,
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true,
    "module": "system",
    "noImplicitAny": false,
    "outDir": "js",
    "rootDir": "app"
  },
  "exclude": [
    "node_modules",
    "typings/main",
    "typings/main.d.ts"
  ]
}

推荐答案

您应将moduleResolution属性用于node:

{
  "compilerOptions": {
    "target": "es5",
    "sourceMap": true,
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true,
    "module": "system",
    "moduleResolution": "node", // <-----
    "noImplicitAny": false,
    "outDir": "js",
    "rootDir": "app"
  },
  "exclude": [
    "node_modules",
    "typings/main",
    "typings/main.d.ts"
  ]
}
