🐛[BUG] @ant-design/pro-components@3.1.14-1: the CommonJS build (`main`, `lib/`) requires antd's ESM build (`antd/es/locale/zh_CN`), so the main entry cannot be loaded by Node

[yuki2006]

🐛 bug 描述 / Description

Follow-up to #9656: "type": "module" was removed in 3.1.13-0 (thanks!), but the package's main entry is still unusable under Node. lib/provider/index.js (CommonJS build) contains:

var _zh_CN = _interopRequireDefault(require("antd/es/locale/zh_CN"));

i.e. the CJS build reaches into antd's ESM build.

• On Node < 22, requiring the ESM-syntax antd/es/locale/zh_CN.js as CommonJS fails with:

  SyntaxError: Cannot use import statement outside a module
      at .../antd/es/locale/zh_CN.js:1
      at Object.<anonymous> (.../@ant-design/pro-components/lib/provider/index.js:19:37)
  

• On Node ≥ 22 (require(esm) support), the file is re-loaded as ESM instead, and its extension-less relative import (../calendar/locale/zh_CN) then fails with:

  Error [ERR_MODULE_NOT_FOUND]: Cannot find module '.../antd/es/calendar/locale/zh_CN'
  imported from .../antd/es/locale/zh_CN.js
  

Either way, require('@ant-design/pro-components') crashes immediately, which breaks any tool that resolves the package through main (Vitest externalizing node_modules, Jest, plain Node SSR, …).

lib/provider/index.js is the only file under lib/ that references antd/es/* — the CJS build should require antd/lib/locale/zh_CN (or the root antd/locale/zh_CN) instead.

📷 复现步骤 / Steps to reproduce

1. npm install @ant-design/pro-components@3.1.14-1 antd@^6 react@^19 react-dom@^19
2. node -e "require('@ant-design/pro-components')"

🏞 期望结果 / Expected

The main (CommonJS) entry can be loaded by Node; the CJS build only references other CJS builds.

💻 复现代码 / Reproduction

Online (CodeSandbox Devbox — run npm install && npm test in the terminal; the devbox runs Node 20, so you get the SyntaxError variant):

🚑 其他信息 / Environment

• @ant-design/pro-components: 3.1.14-1 / antd: 6.5.0 / react: 19.x
• Node: reproduced on both v20.12.0 (SyntaxError) and v24 (ERR_MODULE_NOT_FOUND)

[dosubot]

This is a valid bug. The root cause is that PR #9376 standardized all antd imports from antd/lib/* to antd/es/* across the codebase, including in the provider source at src/provider/index.tsx [1]:

import zh_CN from 'antd/es/locale/zh_CN';

The build tool (Father with Babel transformer) does not use babel-plugin-import or any path-rewriting plugin [2], so this antd/es/* path passes through unchanged into the CJS output at lib/provider/index.js.

While antd v5 had a working lib/ build that could be referenced, antd v6's antd/es/locale/zh_CN.js is pure ESM and cannot be require()'d from CJS — exactly the crash you're seeing.

Fix: The simplest correction would be to change the source import to the root subpath (antd/locale/zh_CN) which antd v6 resolves via its exports map to the appropriate format, or to add a Babel plugin in the CJS build config (.fatherrc.ts under cjs.extraBabelPlugins) that rewrites antd/es/* → antd/lib/* during CJS compilation. Since this is the only file under lib/ hitting this path, patching the source import is the lowest-risk option.
