我正在我的gruntfile.js中执行以下grunt任务：
'typescriptUsingTsConfig': {
'basic': {
'options': {
'rootDir': './ng2'
}
}
}
我从另一个成功运行任务的项目中复制了此任务。当我运行这个任务时，我得到了
这篇文章底部的错误。为该项目安装了2.4.0版本的typescript。我是

好的，所以错误正是它所说的：
＆＃39; C：/CODE/Test/src/Test.Website/typings/globals/core-js/index.d.ts'未找到。 ng2 / services / user.service.ts（37,16）：错误TS2693：＆＃39;承诺＆＃39;仅指一种类型，但正在使用
缺少声明文件。我与Grunt的TypeScript配置并不相似，因为我已经使用了大约3年，但这是我推荐的。
运行
typings uninstall --save core-js
然后运行
npm uninstall --save @types/core-js
以防万一。
然后在你的tsconfig文件中，更改或设置`＆＃34; compilerOptions＆＃34;的"lib"选项。财产如下
{
"compilerOptions": {
"lib": ["dom", "es2015"],
// whatever else you had previously
}
}
最后，您可能需要添加the declaration I suggest in this answer才能解决上一个错误（rxjs / Subject的错误）
此外，如果您对为什么感到好奇，核心j的声明会导致这些问题read my answer to a related question
