"decoder jpeg not available" with Django on Elastic beanstalk

I am developing a Django backend system on Elastic beanstalk.

When I upload JPEG image file, I get the error decoder jpeg not available. Uploading .png image files does not cause any problem.

Backend environment:

Source code causing error:

View

normalImage = NormalImage(image=image, userProfile=request.user.profile, category = category)
normalImage.save()

Model 

class NormalImage(models.Model):
    userProfile = models.ForeignKey(UserProfile)
    height = models.PositiveIntegerField(editable=False)
    width = models.PositiveIntegerField(editable=False)
    image = models.ImageField(upload_to=rename_image_file, width_field='width', height_field='height')
    size = models.TextField()
    price = models.PositiveIntegerField()
    tags = models.ManyToManyField(Tag)
    category = models.ForeignKey(Category)
    created_datetime = models.DateTimeField(auto_now_add=True)

def __init__(self, *args, **kwargs):
    super(NormalImage,self).__init__(*args, **kwargs)
    if not self.id:
        self.size = Size.determineSizeDescription(anWidth=self.width, aHeight=self.height)
        self.price = Size.determinePrice(anWidth=self.width, aHeight=self.height)

def get_created_datetime_str(self):
    return self.created_datetime.strftime('%Y-%m-%d %H:%M:%S')

def get_image_url(self):
    return 'http://photocoapi-env-x2ezvferc7.elasticbeanstalk.com/images/' + str(self.id) + '/'

Error code:

IOError at /me/requests/ decoder jpeg not available Request Method: GET Request URL:

yum could not find libjpeg-devel. But this worked for me:

packages: 
  yum:
    libjpeg-turbo-devel: []

Hope this helps someone.
Cheers!

You can include a file called "requirements.txt" in your app source with all the required dependencies and AWS Elastic Beanstalk will install the dependencies for you.

You can use ebextensions to install yum packages. Create a file called .ebextensions/01-yum.config in your app source and put the following contents in it.

packages: 
  yum:
    libjpeg-devel: [] 
    <another-package>: []

This file is in YAML format so indentation is important.

Read more about pacakges section of ebextensions here:

http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/customize-containers-ec2.html#customize-containers-format-packages

Here is a tutorial on using requirements.txt with Elastic Beanstalk.

The dependencies to support JPEG images must be installed BEFORE you install Pillow with pip (the python library used to decode images).

So you should try to:

  • uninstall Pillow:

    pip uninstall pillow

  • install jpeg libraries:

    yum install libjpeg-devel

  • reinstall pillow:

    pip install pillow
