使用 antd pro 官方脚手架，mfsu 报错！

[lifegit]

使用脚手架 getting-started 生成代码运行报错，内容如下：

Uncaught TypeError: moment__WEBPACK_IMPORTED_MODULE_0___default(...).isMoment is not a function

初步排查，当 config/config.ts 开启 umi 的 mfsu: {}功能， 且使用 @ant-design/pro-form(src/pages/user/Login/index.tsx) 就会出现问题。

解决了吗

解决了吗

你也遇到了吗？

对的

[lifegit]

目前没解决。还是用的Moment，但用了umi的 ignoreMomentLocale

排查结果

debug后发现是执行isMoment报错猜测是不存在isMoment

手动导入isMoment插件发现报了这个错误

[MFSU] require('dayjs/plugin/isMoment') found in C:\Users\dengqing\goldpig-project\golden-pig-walle\packages\express\src\libs\dayjs\format.ts, which will broken the MFSU prebuild match, p

我猜测mfsu不支持require导入，而这个转换插件正是以require的方式去引入所需要的插件，导致moment需要执行的方法都没有extend进去。

https://github.com/ant-design/antd-dayjs-webpack-plugin/blob/32951b4b06991bad356d44e6af73b84cfa478ff3/src/init-loader.js#L6-L12

解决方案如下

手动导入moment需要转换的插件： https://github.com/ant-design/antd-dayjs-webpack-plugin/blob/32951b4b06991bad356d44e6af73b84cfa478ff3/src/index.js#L5-L18

导入方式：

import isMoment from 'dayjs/esm/plugin/isMoment';
dayjs.extend(isMoment as any);

暂时还不知道怎么以webpack插件的方式去修复这个问题

我也排查了一下, 简单地说, 是开了msfu 之后, 用到的那部分代码不在 umi.js里面了; 按我的理解,这个插件就干了2件事情:

1. 改alias 将 import Moment from 'moment' 里的 moment 指鹿为马成 dayjs;
2. 使用了dayjs 插件方法,让dayjs 方法签名和moment 保持一致, 在entry中添加了,dayjs.extends(xxxx);

因为开 msfu之前, antd都打包到 umi里面了, 所以 import Moment from 'dayjs', 之后改动 Moment 其实改得是同一个,

@Dunqing 你的可以了吗？我引入以后日历全变成相同的数了

[lxy94]

我在config设置了 alias：{'moment':'dayjs'}, 并且在用到组件的地方引入了 import dayjs from 'dayjs' import isMoment from 'dayjs/esm/plugin/isMoment'; import badMutable from 'dayjs/esm/plugin/badMutable';

dayjs.extend(isMoment as any); dayjs.extend(badMutable as any); 看起来可以，打包后少了0.02M
