Node.js &引用；Npm列表“；不'；无法显示任何未满足的依赖项，那么为什么我的服务器会出错？

“npm列表”返回此项，其中没有“未满足”项。但当我重新启动服务器时，它会出错，错误日志显示“错误：找不到模块‘async/each’”和其他类似错误。我已经逐一检查并安装了每个未找到的模块，但这非常繁琐。我该怎么做呢

编辑：而且，执行“npm修剪”似乎什么也做不了（“npm列表”仍然会给出很多错误无关的类型。）

编辑2：它不是一个非常复杂的服务器，它只是用来提供一个HTML文件并连接到MongoDB。因此，基本的依赖关系是Express、Socket.io和MongoDB

为了解决这个问题，我删除了build文件夹中的“node_modules”文件夹，对server.js文件中require语句中的每个包都执行了“npm install[module]--save”，清除了我的服务器并将我的构建文件重新同步到它，然后在服务器上执行了“npm install”。

考虑到大量的无关依赖项，我想，因为你的package.json与你的代码实际需要的不匹配，但是如果没有一个，很难说清楚。我添加了我的server.js文件，希望这足够了，如果不让我知道的话。
