Element implicitly has an ‘any’

function proxify(obj: any) {
  // 解决办法：可一个给 res 赋值为 any 类型
  //let res = {};
  let res:any = {};
  for (let k in obj) {
    // Element implicitly has an 'any' type because expression of type 'string' can't be used to index type '{}'.
  No index signature with a parameter of type 'string' was found on type '{}'.
    res[k] = {
      set() { },
      get() { }
    }
  }
  return res;
}

Type ‘Proxy’ is not generic.

// 报错原因是 Proxy 没有设置泛型
type Proxy = {
  name: string,
  age: number
};
type Proxify<T> = {
  // Proxy<T[P]> 报错 Type 'Proxy' is not generic.
  [P in keyof T]: Proxy<T[P]>
};

解决办法

type Proxy<T> = {
  name: string,
  age: number
};
