Asset pipeline DEPRECATION WARNING tsort.rb:226

Question

I have rails 4.2 working fine on development but in production env I have the following warning:

DEPRECATION WARNING: The configuration option `con

Answer 1

The deprecation warning you're getting is most probably caused by another gem that's setting that configuration for you. For me, we're using rails_serve_static_assets and we're using version 0.0.2. To remove the deprecation warning, just update the gem (issue has been fixed in version 0.0.3)

bundle update rails_serve_static_assets

Answer 2

Open your environments file. (either environments/production.rb, environments/development.rb, environments/test.rb) depending on which environment you are in.

Change

config.serve_static_assets

to

config.serve_static_files

Answer 3

I have faced the same issue and it seems a warning and not an error, and railties update automatically the serve_static_assets to serve_static_files as per the configuration file.

Path:
railties-4.2.7\lib\rails\application\configuration.rb

Source code snippet:

  # :nodoc:
  SERVE_STATIC_ASSETS_DEPRECATION_MESSAGE = <<-MSG.squish
    The configuration option `config.serve_static_assets` has been renamed
    to `config.serve_static_files` to clarify its role (it merely enables
    serving everything in the `public` folder and is unrelated to the asset
    pipeline). The `serve_static_assets` alias will be removed in Rails 5.0.
    Please migrate your configuration files accordingly.
