Question

一直试图在Webstorm中设置我的Angular2应用程序，并遇到了npm install的问题，因为'reflect-metadata@0.1.8'有一个未满足的对等依赖项，它失败了。我试图用

手动安装它

      sudo npm install reflect-metadata@0.1.8

但它不起作用。这是尝试npm install时的终端输出：

      sudo npm install 
      angular2-starter@1.0.0 /home/chase/angular2-starter
      ├── es6-promise@3.2.1  extraneous
      └── UNMET PEER DEPENDENCY reflect-metadata@0.1.8

      npm WARN optional Skipping failed optional dependency /chokidar/fsevents:
      npm WARN notsup Not compatible with your operating system or  architecture: fsevents@1.0.14
      npm WARN angular2@2.0.0-beta.17 requires a peer of reflect-metadata@0.1.2 but none was installed.
      npm WARN angular2-starter@1.0.0 No description
      npm WARN angular2-starter@1.0.0 No repository field.

这是我的Package.json文件：

    {
      "name": "angular2-starter",
      "version": "1.0.0",
      "scripts": {
      "start": "concurrently \"npm run tsc:w\" \"npm run lite\" ",

      "postinstall": "typings install",
      "tsc": "tsc",
      "tsc:w": "tsc -w",
      "typings": "typings"
   },

      "core-js": "^2.4.0",
      "es6-shim": "^0.35.1",
      "reflect-metadata": "^0.1.2",
      "rxjs": "^5.0.0-beta.6",
      "systemjs": "0.19.27",
      "zone.js": "^0.6.15"
       },
      "devDependencies": {
      "concurrently": "^2.0.0",
      "lite-server": "^2.2.0",
      "typescript": "^1.8.10",
      "typings": "^1.0.4"
     } 
     }

任何想法？感谢

npm WARN angular2@2.0.0-beta.17 requires a peer of reflect-metadata@0.1.2 but none was installed.表示您需要正确的版本并且没有安装它。您可以通过更正package.json以在版本之前没有插入符号（^）来更改此操作。

  "reflect-metadata": "0.1.2",
  "rxjs": "5.0.0-beta.6",

删除插入符将安装特定版本。但这会阻止安装更新版本。
