The ENOENT probably means some part of the path (one or more subdirectories) is missing. If you're sure that's not the case, then please post a standalone test case, i.e., something that's ready to run.

[ashu8912]

when i tried by giving a manual path it does work

but for the dynamic path its not working the dynamic path for me when i console it is /Users/ashughildiyal/Desktop/WebDevelopment/pirpleNode/app/.data/test/sample.json and thats the exact path no subdirectories missing but it does not works for this path

[ashu8912]

for the baseDir i used path.join(__dirname,"/../.data/") .data is the directory name

I'm going to close this for lack of a standalone test case. I have no reason to believe there is actually a Node.js bug. Try nodejs/help if you want to pursue this further.

I had the same issue - same error when attempting to create a directory/file within .data; however, when I only attempted to create a file in .data, it worked fine.

I agree with @edgewood1 I think this wasn't the case with the older versions of nodeJS. Here's a way to replicate running fs.open('../folderThatExists/folderThatDoesNot/fileThatDoesNot.json', 'wx') So if you try fs.open('../folderThatExists/fileThatDoesNot.json', 'wx') it shall work.

I am having the same issue.. in the filename argument, if I don't use the ${dir} then it works fine... just wanted to know if this worked for any of you guys and if yes, then how?

I am assuming that using 'wx' should allow creation of directory if it doesn't exist too in the path for the filename provided..
