Rubygems not updating
To get started, you may want to read the documentation on the gems to learn their API.
If you have installed rdoc on your system, gem automatically generates the rdoc (Ruby documentation) for all of the gems you install.
You need to be root to install or modify gems, but any user can query the system to find out what is installed.
When you want to find software, you can always check out Ruby Forge (see Resources).
Ruby Gems is a system for managing Ruby software libraries. When you find Ruby software you want to use in a project, gems offer a means of downloading, installing and managing the software.
Ruby's connection with Perl caused converts to ask an obvious question “Where is the CPAN (Comprehensive Perl Archive Network) for Ruby?
When you install it, it will compile the C code as part of the installation process.
Ryan Leavengood is credited with creating the very first Ruby Gems project back in 2001 (see the on-line Resources).
The project got started but did not really gain enough momentum to take off.
You can add the -p option to launch the server on a different port.
This makes it easy for you to use your Web browser to browse the documentation for all of the gems that are installed. Also, be aware that the server accepts connections from all hosts that are able to connect to that port.
