typescript编译Decorators时报错：Unable to resolve signature of method decorator when called as an expression.
解决

1.配置tsconfig.json ---官网推荐（我自己并未解决）

"compilerOptions": {
      "target": "ES5",
      "experimentalDecorators": true
  }

2.命令行

tsc --target ES5 --experimentalDecorators

3.类型定义解决---

创建一个变量接受connect，虽然解决了这个问题，但是重新赋值，并不太推荐

const connect1: any = connect;
@connect1(
  ({ counter }) => ({
    counter
  }),
  dispatch => ({
    add() {
      dispatch(add());
    },
    minus() {
      dispatch(minus());
    }
  })
)
