[typescript] Experimental support for decorators is a feature

用到typescrip装饰器语法，使用命令tsc进行编译时，报错如下

Experimental support for decorators is a feature that is subject to change in a future release.

Set the 'experimentalDecorators' option in your 'tsconfig' or 'jsconfig' to remove this warning.

 

根据提示信息，看了下我实际的配置文件tsconfig.json，已经包含experimentalDecorators:true

 

一个解决办法使用experimentalDecorators选项：

tsc ./src/libs/common.ts --experimentalDecorators
