我如何获得一个需要宝石才能正常运行Ruby的CGI程序？ [英] How do I get a Ruby CGI program that requires a gem to run properly?
问题描述
我已经配置我的Apache安装运行Ruby CGI脚本。现在我想运行需要一个瑰宝一个简单的Ruby CGI脚本。
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.
当我运行在命令行这个脚本，它正确输出。但是，当我把它作为Apache CGI脚本，它会生成一个Apache的内部服务器错误即可。该脚本是这样的：
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>"
Apache的错误日志显示这些行：
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)
[error] [client 127.0.0.1] \tfrom C:/Ruby/lib/ruby/1.9.1/rubygems/config_file.rb:56:in `<class:ConfigFile>'

[error] [client 127.0.0.1] \tfrom C:/Apache/Apache2.2/cgi-bin/cgitest.rb:3:in `<main>'
当我不包括要求'RedCloth行，Apache的执行我的CGI脚本就好了。
When I don't include the require 'RedCloth' line, Apache executes my cgi script just fine.
是否有明显的成才说我在这里丢失？可你，其实，即使是执行需要一个宝石Ruby的CGI脚本？任何见解将大大AP preciated。
Is there someting obvious that I'm missing here? Can you, in fact, even execute a Ruby CGI script that requires a gem? Any insights would be greatly appreciated.
谢谢，

推荐答案
你有没有尝试这个？
require 'rubygems'
require 'RedCloth' # <-- This is the gem
