I am trying to run Django application on AWS LightSail instance.

I have been able to deploy Django application so far but got stuck when I started configuring setting to use AWS S3.
I would like to use my static/media files on S3.

However, I keep getting the Ineternal Server Error 500 with error logs stating 'MouduleNotFoundError' storages.
This error is similar to the error stated in https://community.bitnami.com/t/how-do-i-install-python-packages-in-bitnami-django-stack-in-aws/88764

Here, I would like to paste some screen captures to get you understand the issue correctly.

1) When I do run pip list, the package 'django-storages' is correctly installed. To install django-storages, I have run the command pip install django-storages.

2) In my settings.py, I have stated the module 'storages' in INSTALLED_APPS

If I remove 'storages' from INSTALLED_APPS and restart apache, it works fine.

3) My server error log states ModuleNotFoundError (storages). This is very weird as the package has been installed successfully and correctly.

4) I assume all other settings like wsgi.py, httpd-app.conf etc for deploying Django application on AWS LightSail have been good. I confirmed the site was working fine several times.

It seems like the module installed cannot be loaded properly but It seems like it only applies to 'storages'. If I cannot load django-storages, I am concerned that I might not be able to utilise Amazon S3 to get my static/media files into it.

Could anyone point out what needs to be done to make sure that the modules are correctly loaded when it comes to deployment?

Lastly, this issue is similar to the previous issue raised on https://community.bitnami.com/t/how-do-i-install-python-packages-in-bitnami-django-stack-in-aws/88764/12. Yet, the issue does not seem to have been solved.

Thanks million times.

Kind Regards,

Hello @headfat1218,

I was able to install django-storages and add it without issues following the same steps. Could you double-check that you are using pip binary under bitnami installation?

$ which pip
/opt/bitnami/python/bin/pip

You could also try to install it with the command below:

sudo /opt/bitnami/python/bin/pip install django-storages

I hope it helps

Hello @davidg,

Thanks for your reply. It seems it works now!

I get to see different list of packages installed between

/opt/bitnami/python/bin/pip

and

pip list

Does this mean, I have to use sudo /opt/bitnami/python/bin/pip install <packages> each time I want to install a new package to the project?

Thank you so much for your help!

Kind Regards,

Hi @headfat1218,

Yes. It seems you have another pip installation on your system (you can find it by executing which pip), and it is found before the included in Bitnami Django (/opt/bitnami/python/bin/pip). Alternatively, you could edit your PATH variable to find /opt/bitnami/python/bin/pip before the other pip.

PATH="/opt/bitnami/python/bin:$PATH"
export PATH

After that, pip command should use /opt/bitnami/python/bin/pip.
