I get an error while trying to load any page:
ActionView::Template::Error (variable @fontAwesomeEotPath_iefix is undefined)
(in /app/assets/stylesheets/bootstrap_and_overrides.css.less)):
2: <html>
3: <head>
4: <title>Program</title>
5: <%= stylesheet_link_tag "application", :media => "all" %>
6: <%= javascript_include_tag "application" %>
7: <%= csrf_meta_tags %>
8: </head> app/views/layouts/application.html.erb:5:in `_app_views_layouts_application_html_erb__242882506_70513990' app/controllers/problems_controller.rb:7:in `index'
What I did before? Just run bundle update
Because of bootstrap update I will need to update bootstrap's assets:
rails g bootstrap:install -f
There are a new line in assets:
+@fontAwesomeEotPath_iefix: asset-path("fontawesome-webfont.eot#iefix");
This also happened to me. This is because, When you update your Bootrap gem, You should update Its js and less css. Do
rails g bootstrap:install -f
This will add a line to your app/assets/css/bootstrap_overrides.css.less file like
@fontAwesomeEotPath_iefix: asset-path("fontawesome-webfont.eot#iefix");
