Why use process.env? process.env.NODE_ENV should have defined.

• 修复在 windows 平台下 wrappers 的地址错误的情况
• close https://github.com/umijs/umi/issues/5401

<!-- 感谢您向我们反馈问题，为了高效的解决问题，我们期望你能提供以下信息： -->

What happens?

• 在调试 dumi 的时候，发现生成的 .umi/core/routes.ts 中存在异常数据，其中 wrappers 的路径异常如下

{
    "path": "/",
    "wrappers": [require('D:/projects/dumi/pages/D:/projects/dumi/packages/preset-dumi/lib/theme/layout').default
     ...
}

• 排查之后发现是在 windows 下给 route.wrapper 传绝对路径会被迫 join 上 root, 导致拿到了错误的路径信息
• 虽然可以通过传相对路径来规避该问题，但是我认为这肯定是一个bug

<!-- 清晰的描述下遇到的问题。-->

最小可复现仓库

• 问题简单不需要提供复现仓库了吧，看代码就能看出问题

思路

引用 Route.ts 的一段代码就可以看出来

 if (route.wrappers) {
      route.wrappers = route.wrappers.map((wrapper) => {
        if (wrapper.startsWith('@/') || wrapper.startsWith('/')) {
          return wrapper;
        } else {
          return winPath(join(opts.root, wrapper));
        }
      });
    }

• 这里用 wrapper.startsWith('@/') || wrapper.startsWith('/') 来判断是否为绝对路径不合理，我建议用 path.isAbsolute 来判断
• 如果是 Windows 的绝对路径 比如 D:\projects\xxx\xxx 就会被迫 join 上 root

实验项目均为重新按照官方文档流程新建立的，而不是老项目。 SyntaxError: Invalid regular expression: /(node_modules|D:\workspace\antTest\dist)/: Unterminated group at new RegExp (<anonymous>) at Bundler.setupDevServerOpts (D:\workspace\antTest\node_modules_@[email protected]@@umijs\bundler-webpack\lib\index.js:150:69)

经定位是上述index.js中正则拼接的错误，代码片段： watchOptions: { // not watch outputPath dir and node_modules ignored: process.env.WATCH_IGNORED === 'none' ? undefined : new RegExp(process.env.WATCH_IGNORED || (node_modules|${absOutputPath}${_path().sep})) } 由于${absOutputPath}${_path().sep}=D:\workspace\antTest\dist\中存在\特殊字符，导致生成正则错误，如果只针对开发，可以将后续拼接删除或者变成${absOutputPath}${_path().sep}.*，但觉得不妥，想问问有遇到这个问题的吗，如何解决。

What happens?

Installing umi gives security vulnerability:

How To Reproduce

Steps to reproduce the behavior:

npx @umijs/create-umi-app
npm install

Expected behavior: No "found 1 high security vulnerability"

Context

• Umi Version: 3.2.14
• Node Version: 14.7.0
• Platform: Linux

Solution

Upgrade copy-webpack-builder to 6.0.3: https://github.com/umijs/umi/blob/master/packages/bundler-webpack/package.json#L37

Note: Possible breaking changes: https://github.com/webpack-contrib/copy-webpack-plugin/releases/tag/v6.0.0

补下用例，在现有 fixtures/copy 的基础上，加个 { from, to } 的例子

函数组件国际化可以使用useIntl，在class组件中国际化应该怎么做呢？

相关环境信息

• **Umi 版本3.2.9：
• **Node 版本12：
• **操作系统win2019：

改成 Function 的方式。

检查元素看到全局样式文件被划掉了，应该是引入样式顺序问题，没能成功覆盖antd-mobile样式

加载有先后，通过调整权重的方式覆盖吧。

当项目比较大的时候 , 热更新很慢,有无办法提升一下

热更新慢是因为依赖多，参考 https://umijs.org/zh-CN/guide/boost-compile-speed 这里的方式优化下。

使用ant design pro v5 , yarn start 后无法热刷新,只能修改一个地方,重新yarn start

windows 的没过。

前面的格式乱了，加空格是故意的，还在前面加了 // prettier-ignore，为啥你的工具会做这个格式化？

有冲突，merge 下 master。

const copyPatterns = ...; if (copyPatterns.length) { webpackConfig.plugin('copy').use(...) }

换成这样简单点。

文件 .umirc.ts 的 copy 命令，以前 都支持 form/to 用的挺好的，后来改为了 只允许 string； 那么问题来了： 加入需求是：把文件夹 /src/resource 复制到 /dist , 根据帮助文档，应该写： copy: [ './src/resource', // 尝试了 './src/resource/' 效果一样 ], 但是，无论是 npm run start，还是 npm run build，复制过得的文件夹，丢了 resource ,会把里面的子文件全部复制到根目录； 难道我 需要文件：/dist/resource/* 我需要搞一个 /src/resource/resource 才可以？？？
