javascript - 引用错误 : You are trying to `import` a file after the Jest environment has been torn down: at loadCjsDefault

Question

我正在测试使用 jest 构建一个带有汇总的包，每当我使用 async/await 时都会抛出错误。我不知道出了什么问题。我尝试了不同的灵魂，但它不起作用。

ReferenceError: You are trying to `import` a file after the Jest environment has been torn down.

      watchFiles: [
        'D:\\projects\\js\\published\\builderz\\test\\samples\\pure\\src\\index.js'
      ]
    }".

这是测试文件

import { resolve } from "path";
import builderz from "../src";

jest.useFakeTimers();

describe("production", () => {
  it("test pure js", async () => {
    await builderz({
      isSilent: true,
      paths: [resolve(__dirname, "./samples/pure")]
    });

    // update it later of cource:
    expect(true).toEqual(true);
  });
});

和 babel.config

module.exports = api => {
  api.cache(true);
  return {
    presets: [
      [
        "@babel/preset-env",
        {
          targets: {
            node: "current"
          }
        }
      ]
    ]
  };
};

添加 "testEnvironment": "jsdom"进入 jest package.json 中的键

"jest": {
  "testEnvironment": "jsdom",
  "preset": "react-native",
  ...
