WebStorm 2016.3错误：对装饰器的实验性支持是一个可能在未来版本中更改的特性

Question

嗨，更新到最新的WebStorm，我现在得到这个错误：

Error:(52, 14) TS1219:Experimental support for decorators 
is a feature that is subject to change in a future release. 
Set the 'experimentalDecorators' option to remove this warning.

但是在我的tsConfig中ExperimentalDecorators被设置为true：

{
  "version": "1.5.0",
  "compilerOptions": {
    //...,
    "experimentalDecorators": true,   // <======== HERE
    //...,
  },
  "files": [
    //...
  ],
  "exclude": [ "node_modules" ]
}

Answer 1

WS2016.3仅当文件包含在'files'或'include'tsconfig.json部分时才对该文件应用配置设置。[有关tsconfig.json的更多信息]

因此，配置必须包括所有项目文件（或者，如果您有应用程序的几个部分，您可以有几个tsconfig.json文件）。否则，typescript服务将为文件使用默认的typescript选项。
