问题
I've been struggling for several days now to deploy my Django application to Elastic Beanstalk using the Amazon Linux 2 Python 3.7 platform.
After managing to deploy the app I can't run the command python3 manage.py collectstatic --noinput in order for nginx to be able to serve the static files and thus have all the necessary CSS styles for the Django Admin page.
Right now I have a file named "static.config" in the .ebextensions directory that has the following YAML code:
container_commands:
collectstatic:
command: |
source $PYTHONPATH/activate
python3 manage.py collectstatic --noinput
I added the line source $PYTHONPATH/activate after the first failed attempt following this answer.
I also have a file named "01_python.config" with the following code:
option_settings:
"aws:elasticbeanstalk:application:environment":
DJANGO_SETTINGS_MODULE: "backend_project.settings"
"PYTHONPATH": "/var/app/current:$PYTHONPATH"
"aws:elasticbeanstalk:container:python":
WSGIPath: backend_project.wsgi:application
NumProcesses: 3
NumThreads: 20
"aws:elasticbeanstalk:environment:proxy:staticfiles":
"/static/": "static/"
This is the stacktrace I'm seeing in the cfn-init.log:
2020-11-04 14:06:29,217 [ERROR] Command collectstatic (source $PYTHONPATH/activate

One question that comes to my mind when reading this trace is: why is python 2 being used to execute any scripts?
If anyone managed to solve this issue I would very much appreciate any help. All the documentation and answers I could find where quite outdated (for the Amazon Linux Python 3.6 platform).
The only static files my Django app needs are the styles for the Django Admin page as the application is the backend of an Angular application.
Thank you in advance!
Edit:
"PYTHONPATH":"/var/app/current:$PYTHONPATH". I assume $PYTHONPATH should be an environment variable but when I execute the command
envto see the environment variables of the server, PYTHONPATH is not one of them.As requested in the comments I tried to ssh into de EB instance and run the
python3 manage.py collectstatic --noinputcommand. This is what I got:

During handling of the above exception, another exception occurred:

django.core.exceptions.ImproperlyConfigured: Set the SECRET_KEY environment variable
I activated the virtual environment before running the command and I know the environment variables (including the SECRET_KEY) are loaded because when I ran the command /opt/elasticbeanstalk/bin/get-config environment all of them were printed on the console. This keeps getting more and more confusing.
Another thing that could be useful is that all the static files seem to be in the /static directory.
In my settings.py file I have the following:
STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'static')
From what I understood this should indicate Django to look for the static files in the static directory. Perhaps I understood wrong and here lies the problem.
回答1:
Hey I just deployed my django app successfully with static files. Here's what my config looks like.
django.config
container_commands:
01_collectstatic:
command: "source $PYTHONPATH/activate && python manage.py collectstatic --noinput"
option_settings:
aws:elasticbeanstalk:container:python:
WSGIPath: appname.wsgi:application
aws:elasticbeanstalk:environment:proxy:staticfiles:
/static: static
settings.py
# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/2.1/howto/static-files/
STATIC_URL = '/static/'
STATIC_ROOT = 'static'
The environment variables are for the ebs environment not the EC2 instance itself I think. I also don't see PYTHONPATH when I ssh into the EC2 instance but I do see it in the environment variables for my ebs environment in Environment > Configuration > Software on AWS Console
/var/app/venv/staging-LQM1lest/bin
This is my file structure:
┣ .ebextensions/
┃ ┗ django.config
┣ .elasticbeanstalk/
┃ ┗ config.yml
┣ appname/
