当我通过npm start命令运行我的Angular2项目时，我得到重复的标识符导出“错误。我搜索了很多但找不到我的问题的确切解决方案。你可以找到package.json，typings.json和tsconfig。 json下面。

几天前我遇到了同样的问题。我修改了相同的：

将我的节点版本更新为7.7.2
更新至package.json

"@angular/compiler": "~2.4.9", "@angular/core": "~2.4.9"

现在我的tsconfig看起来像是：

{
  "compilerOptions": {
    "target": "es6",
    "module": "commonjs",
    "moduleResolution": "node",
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "removeComments": false,
    "noImplicitAny": true,
    "lib": [
      "es6",
      "dom"
    ]
  },
  "typeRoots": [
    "node_modules/@types"
  ],
  "types": [
    "core-js",
    "hammerjs"
  ],
  "exclude": [
    "node_modules"
  ]
}

npm启动我的Angular2项目
