Javascript 未找到模块：错误：Can'；t解析'/节点模块/react'；在'/用户/<；用户名>/文件/礼物测试/客户'；

因此，对于我的项目（使用React和Redux），我一直有“找不到模块”的错误。我用google的d&stackoverflow设计了几个解决方案，看到有人说我的node_模块出了问题，所以我删除了它们，还安装了npm（重新安装）。错误仍然存在，我认为这与我的webpack.config.js文件有关

我只是想让构建正常工作，让react元素和组件渲染

错误

因为您需要作为依赖项安装react。要安装，只需执行此命令

npm i react

回答：像这样导入react

从“react”导入react
尝试以下操作：
从“React”导入React从导入中删除
/node\u模块
！实际上，我甚至没有意识到。/node\u模块在那里。。。。。我发誓我没有把它们加在那里哈哈。。。搞什么鬼。
