我不知道如何解决这个问题，但我尝试了很多可能只是愚蠢的事情。我只想完成将我的 react-app 更改为 react-static-app，这样我就可以完成我的项目。Everething 在本地工作，我知道它与服务器和客户端 JS 有关，但我不知道从哪里开始。请帮忙。

这是我从常规yarn build得到的错误：

[ERR_REQUIRE_ESM]: Must use import to load ES Module: 
  C:\my-projoect\node_modules\@babel\runtime\helpers\esm\objectWithoutPropertiesLoose.js
  require() of ES modules is not supported.
  require() of C:\my-projoect\node_modules\@babel\runtime\helpers\esm\objectWithoutPropertiesLoose.js 
    from C:\moji-projekt  i\rost-static\node_modules\react-spring\renderprops.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 objectWithoutPropertiesLoose.js to end in .cjs, change the requiring code to use 
    import(), or remove "type": "module" from 
      C:\my-projoect\node_modules\@babel\runtime\helpers\esm\package.json.

这是我运行yarn build --debug时得到的：

  ReferenceError: window is not defined

没有任何迹象表明问题出在哪里。我已经if(typeof window === "undefined") return null;在我的项目周围放置了所有东西，但没有运气。

这是我的 package.json，以防它有助于解决这个问题：

我假设您错过了对 window 的一些引用，或者您正在使用的某些模块中对 window 有一些引用。

根据 react-static 文档：

“因为 React-Static 代码在运行时在浏览器中使用，在构建和导出期间在节点中使用，所以你的所有代码都是“通用的”或者换句话说是“节点安全的”是非常重要的。”

https://github.com/react-static/react-static/blob/master/docs/concepts.md#writing-universal-node-safe-code

所以用 typeof 检查窗口，为我解决了这个问题。

// 有效

const browserVar = typeof window !== 'undefined' && window.method ? 'browser' : 'node'

// 不起作用

const browserVar = window && window.method ? 'browser' : 'node'
