Collectstatic error while deploying Django app to Heroku

I just updated to Django 1.10 today and had the exact same problem.Your static settings are identical to mine as well.

This worked for me, run the following commands:

1. disable the collectstatic during a deploy

   heroku config:set DISABLE_COLLECTSTATIC=1

2. deploy

   git push heroku master

3. run migrations (django 1.10 added at least one)

   heroku run python manage.py migrate

4. run collectstatic using bower

   heroku run 'bower install --config.interactive=false;grunt prep;python manage.py collectstatic --noinput'

5. enable collecstatic for future deploys

   heroku config:unset DISABLE_COLLECTSTATIC

6. try it on your own (optional)

   heroku run python manage.py collectstatic

future deploys should work as normal from now on

You have STATICFILES_DIRS configured to expect a static directory in the same directory as your settings.py file, so make sure it's there not somewhere else.

Also, do you have any files in that static directory? If you don't then git won't track it and so although it exists locally it won't exist in git. The usual solution to this is to create an empty file called .keep in the directory which will ensure that git tracks it. But once you have some static files in this directory then it won't be a problem anymore.

DO NOT disable collectstatic on heroku with heroku config:set DISABLE_COLLECTSTATIC=1. This will just hide the error and not make your app healthy.

Instead, it's better to understand why the collectstatic command fails because it means something is not right with your settings.

Step 1

Run locally both commands:

python manage.py collectstaticpython manage.py test

You should see one or more error messages. Most of the time, it's a missing variable (for ex: STATIC_ROOT) you must add to your project settings.py file.

It's necessary to add the test command because some collectstatic related issues will only surface with test, such as this one

Step 2

Once you've fixed all the error messages locally, push again to heroku.

Troubleshooting

Remember you can also run commands directly in your heroku VM.If you cannot reproduce locally, run the collecstatic command in heroku and check what's going on directly in your production environment:

python manage.py collectstatic --dry-run --noinput

(Same goes for heroku console obviously)
