osx - How to fix node.js on macOS write to file permission denied error? -

i set node.js write file on local folder such:

note: have use sudo chmod 755 req.txt , sudo chmod 755 bodyhead.txt set permission of file writable.

fs.writefile('/req.txt', req + '\r\n!ended!\r\n', function(err) {   if(err) {     return console.log(err);   } }); fs.writefile('/bodyhead.txt', bodyhead + '\r\n!ended!\r\n', function(err) {   if(err) {     return console.log(err);   } }); 

and received:

{ error: eacces: permission denied, open '/req.txt' errno: -13, code: 'eacces', syscall: 'open', path: '/req.txt' }

as as

{ error: eacces: permission denied, open '/bodyhead.txt' errno: -13, code: 'eacces', syscall: 'open', path: '/bodyhead.txt' }

i set node.js write file on local folder...

but you're not writing local folder, you're writing root of filesystem:

fs.writefile('/req.txt', ...               ^ root of filesystem 

instead, remove leading slashes filenames you're trying write:

fs.writefile('req.txt', ... fs.writefile('bodyhead.txt', ...
