error
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
resolution
一个解决办法使用experimentalDecorators选项：
tsc ./src/libs/common.ts --experimentalDecorators
