I'm deploying to Heroku a Django==2.1.2 and Python==3.6.5 app and i would to manage media and static files with Amazon S3.

Here's my settings.py:

```
INSTALLED_APPS = (
    ...
    'storages',
)

AWS_STORAGE_BUCKET_NAME = '****'
AWS_ACCESS_KEY_ID = '***'
AWS_SECRET_ACCESS_KEY = '***'
AWS_S3_CUSTOM_DOMAIN = '%s.s3.amazonaws.com' %  AWS_STORAGE_BUCKET_NAME

DEFAULT_FILE_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage'

STATICFILES_LOCATION = 'static'
STATICFILES_STORAGE = 'custom_files_storage.StaticFilesStorage'

MEDIAFILES_LOCATION = 'media'
MEDIAFILES_STORAGE = 'custom_files_storage.MediaFilesStorage'

```

Here's my custom\_files\_storage.py:

```
from django.conf import settings
from storages.backends.s3boto3 import S3Boto3Storage

class MediaFilesStorage(S3Boto3Storage):
    location = settings.MEDIAFILES_LOCATION

class StaticFilesStorage(S3BotoStorage):
    location = settings.STATICFILES_LOCATION

```

I have runed:

```
pip install boto

pip install boto3

pip install django-storges

```

I have tried with boto and boto3 but the error keeps

Here's the error output:

```
