Installing gems into IronRuby

Ruby IronRuby
1

Hi,

First post here. Excuse a n00b for silly questions. :slight_smile: I’ve been trying
to figure this out for a short time and while I have an idea, I’d like
some confirmation.

I need to install a gem so I can automate some WPF code. One I’m
planning to use is called bewildr. How do I install gems into Ironruby
in Visual Studio 2010? Is there a specific way to do it? Or is
installing gems into a general ruby (non-ironruby) install sufficient?

Just open cmd and run ‘igem install bewildr’. If IronRuby binaries
folder
is not in the PATH environment variable, browse to it first (this is
where
the igem utility is located).

I think this was a bug in version 1.1. Download the latest bits
(1.1.3http://ironruby.com/download/)
and this should work.

Thanks, that helps. I tried that and igem was in path. However, here is
what I got:

C:\Program Files (x86)\IronRuby 1.1\bin>igem install bewildr
ERROR: While executing gem … (ArgumentError)
Illegal characters in path.

Same thing happens when I try to do update:

C:\Program Files (x86)\IronRuby 1.1\bin>igem update --system
Updating RubyGems
Updating rubygems-update
ERROR: While executing gem … (ArgumentError)
Illegal characters in path.

Any ideas what the problem is? What path is it referring to?

I looked at HOME and it appears to be in order:
C:\Program Files (x86)\IronRuby 1.1\bin>SET HOME
HOMEDRIVE=C:
HOMEPATH=\

I do have the latest (1.1.3). It’s still happening. I think there is an
issue with the path somewhere. Is there any sort of log for this? It’s
rather difficult to figure out where it stumbles without it.

Here is the c/p:
C:\Ironruby\bin>igem update --system --no-ri --no-rdoc
Updating RubyGems
Updating rubygems-update
ERROR: While executing gem … (ArgumentError)
Illegal characters in path.

Nevermind, I got it!

Installed it through NuGet package manager in Visual Studio instead.
Both commands worked just fine!

Eugene,

I’ve found that it is necessary also to run either cmd or powershell
as administrator in order to install gems.

Eugene:

I assume that you installed the latest version (1.1.3)

It would be good to do this first:

igem update --system --no-ri --no-rdoc

(usually you get errors when trying to instar ri and rdoc documentation)

then install using:

igem install bewildr --no-ri --no-rdoc
(same thing)

Hope this works,

Eduardo

Yes - admin mode for cmd is essential for any of this scripting stuff. I
used to run into all sorts of errors, even with normal Ruby updates. I
now have a cmd shortcut on the desktop that asks for admin and has a
couple of other tweak (consolas font, wider window etc)
