When following the getting started guide with the JRuby tarball, after the completion of step 4.3, the application will simply return an error "ExecJS::RuntimeError" at line 6: <%= javascript_include_tag "application" %>
This can be fixed by removing app/assets/javascripts/home.js.coffee
From what I have been able to google (
), rails is depending on the existence of a library to execute javascript, but simply running "gem install therubyrhino" was not fixing the error for me.
if I can suggest adding instructions on installing something like therubyrhino or simply removing coffee files, it would save a lot of time for a beginner.
