I have configured my Apache installation to run Ruby CGI scripts. I am now trying to run a simple Ruby CGI script that requires a gem.
When I run this script from the command line, it outputs correctly. But when I call it as an Apache CGI script, it generates an Apache Internal Server Error. The script looks like this:
#!/Ruby/bin/ruby
require 'RedCloth' # <-- This is the gem
puts "Content-type: text/html"
puts
puts
puts "<html>"
puts "<head>"
puts "</head>"
puts "<body>"
puts "I want to call a gem."
puts "</body>"
puts "</html>"
The Apache error log shows these lines:
C:/Ruby/lib/ruby/1.9.1/rubygems/config_file.rb:56:in `join': can't convert nil into String (TypeError)

When I don't include the require 'RedCloth' line, Apache executes my cgi script just fine.
Is there someting obvious that I'm missing here? Can you, in fact, even execute a Ruby CGI script that requires a gem开发者_开发问答? Any insights would be greatly appreciated.
Thanks, Maurice
Have you try this ?
require 'rubygems'
require 'RedCloth' # <-- This is the gem
