Question

首先，这是在尝试运行我的server.js时出现在cmd上的错误：

C:\Users\Jacob\Desktop\setgame>node server.js

fs.js:427
  return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
                 ^
Error: ENOENT, no such file or directory 'C:\Users\Jacob\Desktop\setgame\C:\User

    at Object.fs.readFileSync (fs.js:284:15)
    at Build.add (C:\Users\Jacob\Desktop\setgame\node_modules\ams\lib\build.js:1

    at Function.Module._load (module.js:312:12)
    at Function.Module.runMain (module.js:497:10)

我很困惑。我在Windows 8.1.1 x64上运行node.js 0.10.26。有任何修复此错误的建议吗？

编辑：这是server.js文件：

Answer 1

你的问题是：

, publicDir = __dirname + '/public'
, depsDir = __dirname + '/deps'

__dirname是当前脚本文件的绝对目录路径。这就是为什么您在错误消息中看到双路径名称的原因。我假设当你执行ams.build.create(publicDir)时，它会设置基本目录以及.add()所有应该相对于该基本目录（publicDir）的路径。

因此，请尝试将depsDir和clientDir分别改为'deps'和'client'。

Node.js app检查错误的目录
