错误是 fetch 未在窗口上定义。当我为测试导入 fetch 时，我是在 setupFilesAfterEnv 中这样做的，所以我添加到 jest.config `setupFiles: ['./jestSetup.js']，

在那个 jestSetup.js

const fetch = require("node-fetch")

global.fetch = window.fetch = fetch;
global.Request = window.Request = fetch.Request;
global.Response = window.Response = fetch.Response;
