'collectstatic' command fails when WhiteNoise is enabled

Question

I'm trying to serve static files through WhiteNoise as per Heroku's recommendation. When I run collectstatic in my development environment, this happens:

Post-processing 'css/iconic/open-iconic-bootstrap.css' failed!

Traceback (most recent call last):

The static collection command runs without incident when I comment out this line in my settings:

STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage'

What's going wrong here and how do I fix it? I already tried emptying my static file output folder. It runs smoothly until it starts processing one specific file.

The problem here is that css/iconic/open-iconic-bootstrap.css is referencing a file, open-iconic.eot, which doesn't exist in the expected location.

When you run collectstatic with that storage backend Django attempts to rewrite all the URLs in your CSS files so they reference the files by their new names e.g, css/iconic/open-iconic.8a7442ca6bed.eot. If it can't find the file it stops with that error.

Is this behavior specific to WhiteNoise? Because I don't experience the issue if I have WhiteNoise disabled. I checked `open-iconic-bootstrap.css` and there's no difference between the original file and the copy in the static folder. – Pieter Nov 13 '14 at 18:49

No it's not WhiteNoise specific: you'll find you get it if you use `django.contrib.staticfiles.storage.CachedStaticFilesStorage` as well. You don't have to use the storage backend to use WhiteNoise, it just gets you better performance. – D. Evans Nov 13 '14 at 19:07

The storage backend is only complaining because your `.eot` font file is missing, so you'll find your icon fonts won't be working in Internet Explorer. If you fix that then `collectstatic` should run without problem. – D. Evans Nov 13 '14 at 19:11
You were right, thanks for helping me understand what was going on! – Pieter Nov 13 '14 at 20:52

Thanks for explaining. But still, do you know any way to fix it ? While obviously still using WhiteNoise. – babttz Apr 23 '15 at 06:41
The fix is either to remove the line in the CSS which references the missing file, or to copy the file into the right place so it's no longer missing. – D. Evans Apr 24 '15 at 08:53

I just had this same issue and fixed it by removing this line from my settings file,

STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage'

I got this line from the Heroku documentation page...

I don't know but this worked for me. Anyone know the repercussions? – Bernard 'Beta Berlin' Parah May 23 '16 at 06:26
I had the same issue, removing GzipManifestStaticFilesStore worked for me too, but it must be another workaround, I want to use file compression. – Carlos Goce Dec 17 '16 at 17:58

@BernardParah you're disabling the [compression and caching support](http://whitenoise.evans.io/en/stable/django.html#add-compression-and-caching-support) from whitenoise. You don't need it to use whitenoise, but it is nice. – gdvalderrama Jan 04 '18 at 17:43
This worked for me as i was using cloudinary which caused issues. Thanks as this was causing me a headache :) – JDavies Apr 13 '18 at 09:03
Hi guys, I have same problem. But in my case I have wrong reference to jquery, I have there extra slash on begining of the path: # this is wrong, path starts with "/admin" # this is ok, path starts with "admin" ``` – msgre Jan 24 '20 at 08:09

I've had this error claiming a missing .css file when all my .css files existed, because I trusted Heroku documentation:

STATIC_ROOT = 'staticfiles'

over WhiteNoise documentation:

STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')

The fix is trivial, but until Heroku fix their docs (I submitted feedback), lets make sure the solution at least appears in SO.

In newer versions of whitenoise there are only two storage classes available:

whitenoise.storage.CompressedManifestStaticFilesStorage
whitenoise.storage.CompressedStaticFilesStorage

This error will arise with CompressedManifestStaticFilesStorage, in cases where any of your static assets refer to other assets that cannot be found by the staticfiles finder. This is because the HashedFilesMixin parses all the files to find references to other assets, so that it can pregenerate hashes for all of them to add to the manifest.

There are two ways to resolve this:

Switch to using CompressedStaticFilesStorage (no Manifest), so that file hashes are not pre-rendered.
Identify all the missing files reported during collectstatic and either ensure that they are present in your collected directories, or remove references to them in your static files.

It does not make sense to remove whitenoise from your cool app. This answer was the only solution that worked for me among many not relevant ones. – JM217 Jun 08 '22 at 12:39

The issue here is that using

STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'

or

STATICFILES_STORAGE = 'django.contrib.staticfiles.storage.ManifestStaticFilesStorage

uses Django's static file storage in a different way than runserver does. See the Django docs for some explanation: https://docs.djangoproject.com/en/1.11/ref/contrib/staticfiles/#django.contrib.staticfiles.storage.ManifestStaticFilesStorage.manifest_strict

I believe the referenced manifest gets built when you run collectstatic, so doing so should fix this problem temporarily, but you likely don't want to run collectstatic before every test run if you have modified any static files. Another solution would be to disable this setting for your tests, and just run it in production.

I had similar problem, but with a twist.

I deployed on pythonanywhere. If I turn debug True, app runs fine. But if a turn debug False, app crashes with a error that with one line being the summary

ValueError: Missing staticfiles manifest entry for 'favicons/favicon.ico'

I changed from STATIC_ROOT = 'staticfiles to STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')

Deleted staticfiles directory, then rerun python manage.py collectstatic.

Now app runs fine

In development Django’s runserver automatically takes over static file handling.

In most cases this is fine, however this means that some of the improvements that WhiteNoise makes to static file handling won’t be available in development and it opens up the possibility for differences in behaviour between development and production environments. For this reason it’s a good idea to use WhiteNoise in development as well.

You can disable Django’s static file handling and allow WhiteNoise to take over simply by passing the --nostatic option to the runserver command, but you need to remember to add this option every time you call runserver. An easier way is to edit your settings.py file and add whitenoise.runserver_nostatic to the top of your INSTALLED_APPS list:

INSTALLED_APPS = [
'whitenoise.runserver_nostatic',
'django.contrib.staticfiles',
# ...]

For me the fix was simply adding a 'static' folder to the top directory (myapp/static did the trick). If you are setting the STATIC_URL but don't have that directory already created, it will throw an error, even though you aren't using that directory for your static files with whitenoise.

STATIC_URL = '/static/'

It worked for me by commenting out the whitenoise in settings.py in production.

#STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage'
#WHITENOISE_ROOT = os.path.join(BASE_DIR, 'staticfiles')

This does work, but now you are no longer using whitenoise so you should remove the app completely – Lewy Blue Jun 18 '18 at 08:46

I've been dealing with this issue all day. It turns out the problem was the staticfiles directory was not checked in to git. I created a dummy file inside this directory, checked it in and everything was fine. This was mentioned somewhere in the Whitenoise documentation too, I believe.

Be sure to check all your settings related to static files, especially making sure the paths are pointing to the right locations. I personally had one of my STATICFILES_DIRS pointing to a wrong path.

Much like everyone else, I had a unique fix to this problem... turns out I had a url() in my styles.css file with bad syntax.

Once I changed:

background-image: url( '../images/futura_front_blank_medium.jpg' );

to

background-image: url('../images/futura_front_blank_medium.jpg');

(notice the subtle difference -- I removed the spaces on either side of the string)

then python manage.py collectstatic worked fine and I didn't get that error.

The whitenoise.django.GzipManifestStaticFilesStorage alias has now been removed. Instead you should use the correct import path: whitenoise.storage.CompressedManifestStaticFilesStorage.

As per the doc here.

In my case there was another solution. In Heroku config I had a setting:

DISABLE_COLLECTSTATIC=0

which should let Heroku collect static automaticly by pushing to heroku master, but it didn`t!.

What I did was removing this setting on

Heroku > my_app > settings > config vars

and after that Heroku collected staticfiles automaticly and problem dissappeard.

I didn't face this issue until building my project's docker image on Linux. I usually build on macOS.

I believe there is a difference in case sensitivity by default between the most common filesystems used by these two OSes.

I solved this issue by renaming the files linked from my CSS to all lowercase.

Previously:

url('/static/Some-File.png')

Now:

url('/static/some-file.png')

'collectstatic' command fails when WhiteNoise is enabled
