为什么我在使用 firebase 时收到尝试导入错误？

Question

我用 React 编写的客户端代码几分钟前还在工作，但突然停止工作了。 我想不通。 我所做的只是删除“README.md”的内容。 谁能帮我解决这个问题？ 运行“yarn start”后出现以下错误。

./node_modules/@firebase/firestore/dist/esm5/prebuilt-db9cc925-eb007c37.js
Attempted import error: 'FetchXmlHttpFactory' is not exported from '@firebase/webchannel-wrapper' (imported as 'v').

为了以防万一，我附上了 package.json。

我的项目几分钟前运行良好。 我会感谢你的帮助。

Answer 1

1. 删除node_modules文件夹
2. 删除package-lock.json
3. 运行npm i重新安装所有软件包
4. 通过 npm i @firebase/webchannel-wrapper 安装 package @firebase/webchannel-wrapper npm i @firebase/webchannel-wrapper --save

希望它对我有用

Answer 2

遇到了同样的问题，感谢@Harkal 回答了这个问题，但是

我没有删除节点模块+ package-lock.json，

我刚刚跑了npm i @firebase/webchannel-wrapper --save

它对我有用

Answer 3

我通过安装旧版本 npm package 而不是新版本解决了我的问题。 我没有删除节点模块 + package-lock.json，我安装了旧版本 (npm i html-to-text@7.1.1)，而不是新版本 (npm i html-to-text@8.0. 0)
