Thanks for your reply. But I don't think those are the reasons, since
I have tried them all, yet it still didn't work.

Please let me give a better description of what I have don't before:

1. Download the raa package and unzip it in my home directory.

2. /home/Frodo/raa/tool/install_www.rb /home/Frodo/public_html/eruby/

install succeed!


When I type http://localhost/~Frodo/eruby/entry.rhtml
in my browser, there was an Internal Server Error.

However, if I tried a simpler rhtml file, that is:
http://localhost/~Frodo/eruby/test.rhtml

It worked!

Here is the content of test.rhtml:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN">
<html>
<head>
<title>eruby example</title>
</head>
<body>
<h1>Enumeration</h1>
<ul>
<%(1..10).each do|i|%>
  <li>number <%=i%></li>
<%end%>
</ul>
<h1>Environment variables</h1>
<table>
<%ENV.keys.sort.each do |key|%>
  <tr>
    <th><%=key%></th><td><%=ENV[key]%></td>
  </tr>
<%end%>
</table>
</body>
</html>


Here is my apache-2.0.43 configuration for ruby:

# If the ruby module is installed, this will be enabled.
<IfModule mod_ruby.c>
  # for Apache::RubyRun
  RubyRequire apache/ruby-run

  # exec files under /ruby as ruby scripts.
  <Location /ruby-cgi>
    SetHandler ruby-object
    RubyHandler Apache::RubyRun.instance
    Options ExecCGI
  </Location>

  # exec *.rbx as ruby scripts.
  <Files *.rbx>
    SetHandler ruby-object
    RubyHandler Apache::RubyRun.instance
  </Files>

  # for Apache::ERubyRun
  RubyRequire apache/eruby-run

  # handle files under /eruby as eRuby files by eruby.
  <Location /eruby>
    SetHandler ruby-object
    RubyHandler Apache::ERubyRun.instance
    Options ExecCGI
  </Location>

  # handle *.rhtml as eruby files.
  <Files *.rhtml>
    SetHandler ruby-object
    RubyHandler Apache::ERubyRun.instance
  </Files>

  # for Apache::ERbRun
  RubyRequire apache/erb-run

  # for debug
  RubyRequire auto-reload
</IfModule>


Thanks a lot!
