Multer error enoent no such file or directory open

ENOENT: no such file or directory .?

This is error which am getting while post data and file. I have followed ‘academind’ tutorial for building Restful API services, also i have been searching answer for this type of errors but nothing works for me.

Am using «multer» to upload file

The folder ‘uploads’ available in the folder but it shows

ENOENT: no such file or directory, open ‘D:projectuploads2018-01-24T07:41:21.832Zcheck.jpg’»

After new Date().toISOString() add replace() to change «:» to an accepted character.

Windows OS doesn’t accept files with a «:»

The person on Youtube is using MAC OS

Try the following:

Require this as a constant (const path = require(‘path’);)

Change this line

As I can see, you are trying to get a path that is not on served on the server, but rather a path that is on the server machine.

UPDATE

Try also changing this

In order to expose the __dirname for static files.

This what worked for me. I changed ‘./uploads/’ into ‘__dirname’ so that it can find the correct directory/filename anywhere on your computer.

Because when you set a specific folder name/directory you limit your image directory to be only or should be in that folder.

So the answer is in the tutorials comments section on youtube. Instead of:

I am doing the same course and I too had the same problem (i also use windows machine). The following worked for me:

This creates a unique hash for the filenames as well

OK guys, in case someone has an issue with this in the file creation stage, that probably means you’re working on Windows. Now, you don’t need to feel discouraged and throw your computer to the trash (I actually like always having to find workarounds for my Windows :).

There’s at least a solution, and this is the one I found. My problem is the file does not get created because Windows does not accept filenames with colon (‘:’) on it. My solution is rather simple. After I get the current date, I use replace() and a regexp to change that into a dash. Viola. It works!

Hope it helps someone who´s working in windows.

I came across the same error while saving the file. The path I provided in callback didn’t exist already that’s why I got that error

With filesystem I created the same folder, In case of folder exists the err gets value but here nothing to worry about as we have that folder. This worked for me. hope this would help

ENOENT error when deploy to heroku #591

and port is set to:
var PORT = process.env.PORT || 3000;
project structure:

what did i mess up?

Thanks in advance!

The text was updated successfully, but these errors were encountered:

It seems like the /app/static/uploads/ directory doesn’t exist. Might it be that the Heroku client doesn’t upload empty folders? Or that it’s ignored in some .*ignore file?

I would suggest creating the directory when the process starts for the first time:

@LinusU
my code
const storage = multer.diskStorage( <
destination : function(req,file,cb) <
cb(null,’./public/gambar/’)

>,
filename : function(req,file,cb) <
cb(null,file.fieldname + ‘-‘ + Date.now() + ‘.jpg’)
>
>)
after im upload via application
this path
http://batikmart.herokuapp.com/dashboard/product/uploads/flPhoto-1540382362434.jpg
not same with destination

so image crash and doesnt upload to path destination

@LinusU
in my app.js im set app.use(express.static(path.join(__dirname, ‘public’)));

@kukode does the folder gambar exist?

Could you change ‘./public/gambar/’ to something like this?

I was having the same issue after deploying my Mean Stack app to heroku.
I was pushing the code with empty uploads folder. After adding a temporary file in uploads folder , Issue is gone.

saved my day, thank u very much. but why it happen tho?

Seems like the problem is that Heroku strips empty folders. As mentioned, placing an empty file in the upload folder works around that 👍

You saved my life! thank you!

Thank you so much, everyone. Empty folders were indeed the case.

I did some googling and found out that Heroku doesn’t exclude empty folders, Git does.
If you’re using GitHub along with Heroku, you can clearly see that there are no empty folders. In Heroku CLI, if you do a heroku run dir , you can see the that the empty folders are missing. The usual workaround for this is to keep a file called .gitkeep in the empty folders.

Thank you a million times!! It worked.

What about if i want to upload my images to heroku server ? without cloudinary or etc . ? can we do that just with heroku server ?

In this tutorial, we will help you to resolve the Error: ENOENT: no such file or directory, open
'student.json' issue.

Q: What is fs module in Nodejs?
Ans:

Node.js provides an inbuilt component called FS (File System). The Node. js file system module enables
us to interact with our computer’s file system.

Error: ENOENT: no such file or directory

Error: ENOENT: no such file or directory, open 'student.json'
    at Object.openSync (node:fs:585:3)
    at Object.readFileSync (node:fs:453:35)

Follow below steps to resolve Error: ENOENT: no such file or directory, open 'student.json'
issue.

1. This problem occurs when a file does not exist; therefore, check to see if the file exists first.
2. The suitable approach is to use fs.openSync, it
   returns the file descriptor.
3. If the file does not exist, the w flag ensures that it is created, and if it does, it
   is overwritten
   with a new file, overriding its content.
4. If users don’t need the file descriptor, users can close the file by wrapping the call in a
   fs.closeSync() call.

//check if file exist
if (!fs.existsSync('student.json')) {
    //create new file if not exist
    fs.closeSync(fs.openSync('student.json', 'w'));
}

Я хочу загрузить изображение с помощью multer, но когда я меняю свой app.js, я пробовал много решений, но у меня не сработало

var multer = require('multer');
var path = require('path');
var id_photo = uuidv1();

global.appRoot = __dirname;

var storage = multer.diskStorage({

destination: function(req, file, callback) {
    callback(null, './uploads')
},
filename: function(req, file, callback) {
    callback(null, file.fieldname + '-' + id_photo + path.extname(file.originalname));
}
})

var upload = multer({
storage: storage,
fileFilter: function(req, file, callback) {
    var ext = path.extname(file.originalname)
    if (ext !== '.png' && ext !== '.jpg' && ext !== '.gif' && ext !== '.jpeg') {
        req.fileValidationError = "Only Image Allowed";
        return callback(null, false, req.fileValidationError)
    }
    callback(null, true)
}
}).any();

app.use(upload);
connection.init();

К

var multer = require('multer');
var path = require('path');

global.appRoot = __dirname;

var storage = multer.diskStorage({

destination: function(req, file, callback) {
    callback(null, './uploads')
},
filename: function(req, file, callback) {
    var id_photo = new Date();
    var dd = id_photo.getDate();
    var mm = id_photo.getMonth() + 1; //January is 0!
    var yyyy = id_photo.getFullYear();
    var h = id_photo.getHours();
    var i = id_photo.getMinutes();
    var s = id_photo.getSeconds();
    if (dd < 10) {
        dd = '0' + dd
    }

    if (mm < 10) {
        mm = '0' + mm
    }

    if (h < 10) {
        h = '0' + h
    }

    if (i < 10) {
        i = '0' + i
    }

    if (s < 10) {
        s = '0' + s
    }
    id_photo = mm + '-' + dd + '-' + yyyy + '-' + h + ':' + i + ':' + s;
    callback(null, id_photo + "*-" + file.originalname);

}
})

var upload = multer({
storage: storage,
}).any();

app.use(upload);
connection.init();

Я получаю такую ​​ошибку

Ошибка:

ENOENT: no such file or directory, open
‘C:Nodejsnodejs-wmcuploads4-11-2018-13:20:09*-8.jpg’
at Error (native)

Тогда как загрузка файлов уже существует, когда я использую app.js, первый работает без сбоев. что не так с моим кодом?

Пожалуйста, помогите мне … спасибо
