Is Ruby designed to run only on Linux?

Iam forced to ask this question because of what I have seen from the little I have worked with Ruby. The Ruby core itself installs and runs fine on windows. Its only when you want to install some gems that the problem arises. The command to install the gem is

c:\>ruby gem install

This failed with the message that 'NMake' was not found. I checked on the net and found a link at Microsoft.com where I could download 'NMake'. After I downloaded and copied 'NMake' to 'c:\ruby\bin', the error I got was 'cl' was not found. If I remember correctly 'cl' is the microsoft C compiler. I tried to replace 'nmake' with make and cl with gcc by downloading cygwin. But I couldn't figure out the place where I would change 'nmake' to 'make' since most of the files seem to be generated files. So the gem install process overwrites my changes. This is what has caused me to pose the question above which is

"Is ruby designed to run only on linux?"

For running Ruby under Windows, I recommend the Ruby One-Click Installer. It includes RubyGems, and I have had no problems with it over the past year. To install gems, simply open a command window and type "gem install [gem_name]".

Hi,
You wrote "It has Ruby gems already installed". Does this mean that Ruby gems is a pre-packaged set of APIs on top of Ruby. Excuse me but Iam really new to Ruby. Is it not possible that some gem may exist which is not part of Ruby Gems and has to be installed separately.

Regards,
prakash

RubyGems is a package manager that provides a standard for packaging and distributing Ruby libraries.

Nearly all libraries I have needed are now available on the official gems server, allowing for easy installation using the 'gem install ...' command.

While most Ruby libraries these days are packaged as gems, there are indeed some that are not; wxRuby 0.6 being one example that comes to mind.

You will also find the RubyGems User Guide useful:

By "only Linux" what you actually mean "not Windows." Ruby comes pre-installed on OSX and, because it's BSD-variant, plays just as nicely as Linux with Ruby's internals.

The Zed said...

Prakash: Rubygems plays well with Windows when installed by the One-Click Installer. But you will be blocked by your systems's lack of compiler if you try to install a gem that includes a native extension that needs to be compiled at install time. And true enough, THAT does not work too well if you do not have the same compiling environment as the one used to build Ruby (including C run-time DLL versions), it used to be Visual Studio 6, but I *think* they switched to 2005 recently, now freely available from Microsoft in a simplified version here: http://msdn.microsoft.com/vstudio/express/default.aspx

I am running vista and had no problems installing ruby, gems and rails

Most gems have a pre-compiled win32 package. Take a look at the list of packages that gems gives you to see if it is available.

Hello everyone!
I would like to burn a theme at this forum. There is such a thing, called HYIP, or High Yield Investment Program. It reminds of financial piramyde, but in rare cases one may happen to meet a company that really pays up to 2% daily not on invested money, but from real profits.

For several years , I earn money with the help of these programs.
I don't have problems with money now, but there are heights that must be conquered . I get now up to 2G a day , and I started with funny 500 bucks.
Right now, I'm very close at catching at last a guaranteed variant to make a sharp rise . Visit my web site to get additional info.
