typescript - Webstorm、TypeScript、Angular2、Transpiler、重复标识符错误消息

Question

操作系统:Windows Pro 10
Webstorm:ver 11.0.1
AngularJS:ver 2.0.0-alpha.46

WebStorm 设置

1. 工具 – 文件观察器:Babal

2. 语言和框架 – JavaScript:
   JavaScript 语言版本:ECMAScript 6

3. 语言和框架 – TypeScript:
   启用 TypeScript 编译器(选中):
   使用 tsconfig.json(选中)

项目结构:

- bin
- node_modules/angular2
- src/tsconfig.json
- package.json

Package.json

{
  "name": "TypeScriptHTMLApp2",
  "version": "1.0.0",
  "dependencies": {
    "angular2": "2.0.0-alpha.46",
    "es6-shim": "^0.33.13",
    "systemjs": "0.19.6"
  },
  "devDependencies": {
    "babel-preset-es2015": "^6.3.13"
  }
}

tsconfig.json

{
  "compilerOptions": {
    "target": "es6",
    "module": "commonjs",
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "removeComments": false,
    "noImplicitAny": false
  },
  "exclude": [
    "node_modules"
  ]
}

注意:webstorm 项目窗口中的 node_modules 文件夹，也已设置为“排除”。

因此 webstorm 抛出以下重复标识符错误消息:

我该如何解决这个问题？

当两个文件都在编辑器中打开时会发生这种情况。如果您关闭其中一个文件，错误就会消失...
