如何解决Nodejs:错误:ENOENT:没有这样的文件或目录

问题描述

我有一个 Nodejs Web 应用程序当前在服务器上成功运行.现在我正在尝试在我的开发服务器上设置一个本地副本.

I have a Nodejs web app currently running on a server successfully. Now I'm trying to setup a local copy on my Development server.

我目前安装了 Nodejs、NPM 和 Mongo，就像我在生产服务器上安装的一样，但是当我尝试启动节点服务器时出现以下错误

I currently have Nodejs, NPM and Mongo Installed just like what I have in production server however the error below occurs when I try to start node server

是什么导致了这个问题?

Whats could be causing this issue?

fs.js:640
  return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
                 ^

推荐答案

您的应用程序希望在 /home/embah/node/nodeapp/config/config.json 找到一个文件，但该文件不存在(这就是 ENOENT 的意思).因此，您要么需要创建预期的目录结构，要么配置您的应用程序，使其在 config.json 的正确目录中查找.

Your app is expecting to find a file at /home/embah/node/nodeapp/config/config.json but that file does not exist (which is what ENOENT means). So you either need to create the expected directory structure or else configure your application such that it looks in the correct directory for config.json.
