Ruby Thin Server: An Unexpected ActionView Template Error

Encountering an issue when trying to deploy my project on Amazon Web Services and accessing the domain.

ActionView::Template::Error (Command 'java -jar /home/ubuntu/.rvm/gems/ruby-2.1.10@silk/gems/yui-compressor-0.12.0/lib/yui/../yuicompressor-2.4.8.jar --type css --charset utf-8 /tmp/yui_compress20190221-3152-1wh64vu' returned non-zero exit status
  (in /home/ubuntu/ssc-staging/app/assets/stylesheets/application.css)):

    8:     %meta{:name => 'viewport', :content => 'width=device-width, initial-scale=1.0'}/
    9:     = favicon_helper
    10:     = stylesheet_link_tag 'application', "//ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery-ui.css"
    11:     = yield :css
    12:     = javascript_include_tag 'application'

The error message above is associated with this page.

The specific error occurs at line 10, which is a stylesheet link tag to jquery-ui.css. Removing this line allows the project to load without CSS styling. The project runs without issues when tested locally.

No changes have been made to the 'application.html.haml' file. Even after rolling back to previous commits where the project worked flawlessly, the same error persists.

The Ruby web server used is Thin in conjunction with Nginx.

Answer №1

Fortunately, I was able to resolve this issue by discovering that yui_compressor actually needed Java to be present in the server environment. Once Java was installed, everything started functioning properly as expected.
