Next.js 12 与 theme-ui 一起使用时会中断，给出“code: 'ERR_REQUIRE_ESM'”

Question

我正在使用Next.js 12 ，在使用theme-ui创建主题后弹出此错误

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: E:\fm-nextjs\node_modules\@mdx-js\react\index.js
require() of ES modules is not supported.
require() of E:\fm-nextjs\node_modules\@mdx-js\react\index.js from E:\fm-nextjs\node_modules\@theme-ui\mdx\dist\theme-ui-mdx.cjs.dev.js 
is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from E:\fm-nextjs\node_modules\@mdx-js\react\package.json.

  code: 'ERR_REQUIRE_ESM'
}

我的 package.json 有以下依赖项

  "dependencies": {
    "@emotion/react": "^11.7.1",
    "@emotion/styled": "^11.6.0",
    "@mdx-js/react": "^2.0.0",
    "@theme-ui/presets": "^0.13.1",
    "next": "^12.0.10",
    "react": "^17.0.2",
    "react-dom": "^17.0.2",
    "theme-ui": "^0.13.1"
  }

我尝试删除"type": "module"，E:\fm-nextjs\node_modules\@mdx-js\react\package.json但仍然出现错误。
我实际上该如何解决这个问题。看来我必须手动更改一堆文件。如果有解决方法就太好了。

降级@mdx-js/react至1.6.22

通常在这种情况下，最好开始降级最新安装的软件包（特别是因为@mdx-js似乎已经增加了主要版本）
