ActionView::Template::Error at / uninitialized constant

Question

I'm getting the following error when I try to load my app:

ActionView::Template::Error at /
uninitialized constant ActionView::CompiledTemplates::EXPR_ARG

The error is found at app/views/layouts/application.html.haml and the follow code is highlighted.

!!! 5
%html{:lang => "en"}
  %head
    = render partial: 'common/html_head'
  %body#static{ class: body_css_class }
    = content_for?(:base_content) ? yield(:base_content) : yield

Does anyone have an idea on what this is?

Answer 1

This is a known bug in haml gem, version 5.0.1 - 5.0.4.

You need to update the gem version to 5.0.4.
