Question

当我为我的项目运行webpack时，出现此错误，表明React-Redux软件包无法解析其某些内部模块：

任何人不知道如何解决此问题吗？可能是因为我在redux之前安装了react-redux吗？如果是这样，我该如何解决。我已经尝试删除package-lock.json并删除node_modules并重新运行npm install。我还深入研究了文件系统，发现文件系统上存在无法解析的模块。例如，即使webpack无法解析./components/Provider，文件node_modules/react-redux/es/Provider.js仍然存在并且看起来不错。

这是package.json的相关部分。是版本不匹配还是什么？

太棒了，我终于可以使用它了！最后的窍门是删除整个项目文件夹，然后从GitHub重新安装它。已安装的node_modules肯定有问题，甚至rm -rf也无法解决。

编辑：我撒了谎。显然，当我删除该项目并从GitHub重新加载该项目时，我不小心将提交添加到了Redux的所有内容中，并在将其重新带回时又返回了错误。精算发生的是我的webpack.config.js文件中的错误：

我曾经是"extensions": [".ts", ".tsx"]

我需要的是"extensions": [".ts", ".tsx", ".js"]

因此，即使存在JS文件，Webpack仍然忽略了它们，因为配置文件中缺少".js"扩展名。添加这四个字符可解决此问题。这样就结束了长达数小时的调试会话。希望这可以帮助其他愚蠢的人搞砸他们的Webpack配置，然后尝试使用它来加载React-Redux。

React Redux无法解析自己的模块
