Düğüm JS Hata: ENOENT

Birlikte takip ediyorum: The Node Beginner Book

Başka bir yazı: kod ile test ettikten sonra

var Fs = require('fs');

var dirs = ['tmp'];
var index;
var stats;

for (index = 0; index < dirs.length;   index)
{
    try
    {
        stats = Fs.lstatSync(dirs[index]);
        console.log(dirs[index]   ": is a directory? "   stats.isDirectory());
    }
    catch (e)
    {
        console.log(dirs[index]   ": "   e);
    }
}

Hata devam ederse:

Hata: ENOENT, böyle bir dosya ya da dizin '' . tmp

app dir structure

Tmp izinlerini 777.
