There are many question similar to my question on stack overflow. However not solved my problem.
I am getting this error on Ubuntu 18.04:
Error: EXDEV: cross-device link not permitted, rename ‘/tmp/upload_df97d265c452c510805679f968bb4c17’ -> ‘/home/haider/workspaceNode/DSC_0076.JPG’
I Tried This code
var http = require('http'); var formidable = require('formidable'); var fs = require('fs'); http.createServer(function (req, res) { if (req.url == '/fileupload') { var form = new formidable.IncomingForm(); form.parse(req, function (err, fields, files) { var oldpath = files.filetoupload.path; var newpath = '/home/haider/workspaceNode/' + files.filetoupload.name; fs.rename(oldpath, newpath, function (err) { if (err) throw err; res.write('File uploaded and moved!'); res.end(); }); }); } else { res.writeHead(200, {'Content-Type': 'text/html'}); res.write('<form action="fileupload" method="post" enctype="multipart/form-data">'); res.write('<input type="file" name="filetoupload"><br>'); res.write('<input type="submit">'); res.write('</form>'); return res.end(); } }).listen(8081);

Answer
I suppose that Node’s fs.rename
cannot rename across filesystems (that is, limited to link/unlink within one filesystem).
Wherever your /home
is, it’s a safe bet to suppose that /tmp
is a tmpfs filesystem actually residing in memory. (You can check in the output of mount
.)
So, to move a file, you have to fs.copyFile
your data to the destination, then fs.unlink
the original downloaded file.
