Error when recompiling asset

[ccfiel]

When rails precompile the assets
RAILS_ENV=production bundle exec rake assets:precompile

I got this error
No such middleware to insert before: "ActionDispatch::Static"

Any idea how to resolve this?

This gem only works if you are NOT precompiling your assets in production, because it requires asset requests to go through the Rails app, and if you precompile your assets then you are most likely serving them through a web server like NGINX. If this is the case, don't use this gem but instead look into configuring the CORS headers for font requests. For example, here is a way to do that in NGINX.
