How to resolve Sprockets::DoubleLinkError application.css

Question

I'm experiencing this error while pushing to heroku repo

remote:        rake aborted!
remote:        Sprockets::DoubleLinkError: Multiple files with the same output path cannot be linked ("style.css")
remote:        In "/tmp/build_f430cee0cae4a9543fac20926137c7cc/app/assets/config/manifest.js" these files were linked:
remote:          - /tmp/build_f430cee0cae4a9543fac20926137c7cc/app/assets/stylesheets/style.css
remote:          - /tmp/build_f430cee0cae4a9543fac20926137c7cc/app/assets/stylesheets/style.scss

I have tried these suggestions:

1. I deleted the .css file and kept the .scss (there are no duplicates AFAIK)
2. cleared temp directory with heroku run rake tmp:clear
3. reset repo with heroku repo:reset -a <app name>
4. heroku repo:purge_cache -a <app name>

But I still keep getting the error when I push to the Heroku remote

Did you check in your changes into the repo too after deleting the .scss file? – Strand

Try to clean the precompiled assets on Heroku with rake assets:clobber – Strand

Answer 1

For me, this simply occurred because I had two style sheets where I should have had only one. In my case, I had

myapp/app/assets/stylesheets.application.css

AND

myapp/app/assets/stylesheets.application.css.scss

where I should have had just one of those

I removed application.css and the problem went away
