मैं साथ में चल रहा हूं: द नोड बिगिनर बुक
किसी अन्य SO पोस्ट से कोड के परीक्षण के बाद:
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);
}
}
त्रुटि बनी रहती है:
त्रुटि: ENOENT, ऐसी कोई फ़ाइल या निर्देशिका 'tmp' नहीं
Tmp पर अनुमतियाँ 777 हैं।

थोड़ा स्टम्प्ड, किसी भी मदद की सराहना की।
