Precompiling assets throws "Errno::EPERM: Operation not permitted @ sys_fail2" in Rails

Question

I have deployed my rails application on the server but it is showing me an error when i try to precompile the assets also, whenever I try to run my server in production environment it throws ActionController::RoutingError (No route matches [GET] "/stylesheets/application.css"): error everytime. As this Question suggest here to precomplie your assets. but i am still getting this error:

deploy@TTP:/srv/ttp$ RAILS_ENV=production bundle exec rake assets:precompile

Answer 1

The problem is your compiled assert is saved here

/assets/application-b70462741c5220649c0fae6b371f8bb0db1f69df9980817ca94517d13ec3e90e.js

but your client tries to get

/stylesheets/application.css

You should change the path of the CSS assert on your client. if you confuse, post your template where you set the CSS file.

Answer 2

I have fixed this exact same error by removing all directories within my releases/ directory and running cap deploy again.

Can't explain, but I thought this might help someone!
