Collectstatic error while deploying Django app to Heroku

python django heroku deployment collectstatic

Solution 1

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:

disable the collectstatic during a deploy

heroku config:set DISABLE_COLLECTSTATIC=1
deploy

git push heroku master
run migrations (django 1.10 added at least one)

heroku run python manage.py migrate
run collectstatic using bower

heroku run 'bower install --config.interactive=false;grunt prep;python manage.py collectstatic --noinput'
enable collecstatic for future deploys

heroku config:unset DISABLE_COLLECTSTATIC
try it on your own (optional)

heroku run python manage.py collectstatic

future deploys should work as normal from now on

Solution 2

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.

Solution 3

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 collectstatic
python 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)

Solution 4

Run python manage.py collectstatic locally and fix any errors. In my case there were reference errors that prevented that command from running successfully.

Solution 5

This error has occurred because you do not have staticfiles in your Project's Root Directory.
Don't worry. The solution is SIMPLE.
You only need TWO STEPS.

Step 1: Open your settings.py file and write

import os
from pathlib import Path

BASE_DIR = Path(__file__).resolve().parent.parent

STATIC_ROOT = BASE_DIR / 'staticfiles'

Step 2: Run below given command in terminal in your Project's root directory. (If you are using any Virtual environment for Django Project then go inside your Virtual environment and then go into your Project's root directory and then run below given command.)

python manage.py collectstatic

Congrats : Your Problem is Solved.

Now, you can COMMIT and PUSH your "changes" so that it is reflected in your Repository and then you are good to go.

I'm trying to deploy a Django app to Heroku, it starts to build, download and installs everything, but that's what I get when it comes to collecting static files

Any thoughts?

I have tried to do that, but it doesn't seem to work. I created one also in the root directory, just to try, but the result is the same.

This worked for me because I actually had an empty static directory in my project package in my Django app as all my static files were in the static directory inside the main app package.

This worked like a charm! My static folder was empty and adding an empty .keep file did the trick for me.

In my case I needed to fix some errors with python manage.py collectstatic so DISABLE_COLLECTSTATIC would have been a band aid...

Hi Tom, in your step 4 I got the error :raise ImproperlyConfigured("You're using the staticfiles app " django.core.exceptions.ImproperlyConfigured: You're using the staticfiles app without having set the STATIC_ROOT setting to a filesystem path. any idea ?
citynorman over 6 years

As a side note, serving static files with whitenoise and debug=False on heroku ended up being a total clusterf*** and I couldn't get it to work after messing around for 2 days. I ended up setting up an aws s3+cloudfront with the staticfiles and setting STATIC_URL = 'https://xxxxxxxxxxxxxx.cloudfront.net' and it works beautifully.

I had /static completely ignored so it was not adding it at all. Thanks, it would've taken me forever to figure this out.

Have no idea why this works but this solved my problem so +1.

Thanks this helped me too. I created the static files directory in the app folder not the main project folder.

You have a typo there: I think it should be heroku config:set DISABLE_COLLECTSTATIC=1

@Ben2pop, add STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') to your settings.py file, better under STATIC_URL

when I ran heroku config:set DISABLE_COLLECTSTATIC=1 i got ` › Error: Missing required flag:` ` › -a, --app APP app to run command against` ` › See more help with --help`

thanks, after put something in static folder then issue fixed
AfriPwincess almost 3 years

Thanks a lot. I created the static directory and adding a folder and an empty file to it and it works now.

What the heck does bower have to do with anything?
The Sammie almost 3 years

This is a helpful answer. Disabling COLLECTSTATIC is a workaround like someone mentioned in one of the answers below. I found out that for my case, I hadn't set the SECRET_KEY config var on Heroku and once I put it up, everything worked.

Wouldn't this enable DEBUG in production which is a big no-no? It should be set to false.
