After gem update: test fail with “Asset was not declared to be precompiled in production”

Question

Since I updated several gems all tests fail with the error:

ActionView::Template::Error: Asset was not declared to be precompiled in production.

A

Answer 1

I had a similar error and had to edit my manifest.js file in order to get it to work.

Edit /assets/config.manifest.js and then

// manifest.js
//= link_tree ../images
//= link_tree ../stylesheets .css

Then do a bundle exec rake assets:precompile
