目前尚未启用对实验性语法“flow”的支持 (5:8)：react/typescript

Question

我对单元测试非常陌生，每次我修复一件事时，它都会抛出一个新错误，在此之前它说 React 未定义。在此之前它说文档未定义。正如你可以想象的那样，我不得不改变很多不同的事情。有人能告诉我发生了什么事吗？

新的错误正如标题所示 -

export type UsersList = {
        |        ^
      6 |   first: string;

和...

ReferenceError: regeneratorRuntime is not defined

      23 |     setLoading(true);
      24 |
    > 25 |     const fetchList = async (): Promise<UsersList> => {
         |                    ^
      26 |       const result: any = await fetch("https://randomuser.me/api/?results=20")
      27 |         .then((res) => res.json())
      28 |         .then((data) => {
