我已经在angular2项目中安装并添加了ng2-bootstrap，但是我有编译错误。好像和Typescript 2有关联，好像我的 package.json 中配置了错误的版本，但事实并非如此，请看：

包.json：

  "version": "1.0.0",
  "description": "QuickStart package.json from the documentation, supplemented with testing support",

  },

"devDependencies": {
    "concurrently": "^2.2.0",
    "lite-server": "^2.2.0",
    "typescript": "^2.0.2",
    "typings": "^1.0.4",

    "canonical-path": "0.0.2",

    "karma-jasmine": "^0.3.8",
    "protractor": "^3.3.0",
    "rimraf": "^2.5.2"
    },
"repository": {}
}

行的错误示例：

private readonly trueValue;

错误：

Duplicate identifier 'readonly'.
Cannot find name 'trueValue'.

知道我做错了什么吗？

我自己回答。这是一个菜鸟问题。Visual Studio 2015 不是最新的，因为我还在使用 TypeScript 1.8 版本。

更新后，一切都变了。

我也遇到了这个错误，在我的情况下，这是由于我本地安装的 typescript 仍然是早期版本，而全局版本已更新到 2.1.0。一旦我在 package.json 中指定了最新版本，问题就解决了。
