After upgrading to IronRuby 1.1.1, I try run IIRB, and I get the following exception: Have I screwed up my install? What I did was this: 1. Ran the IronRuby installer 2. Copied the bin and lib folders to a local folder that I have checked into source control (to deploy IronRuby to other machines) 3. I wanted the dll’s, and the installer seemed to ONLY (!?!?!?) put them in the GAC, so I went into the GAC and copied them out, then put them in my local ruby/bin folder The bytes are [B8] if running in powershell and [D0] in cmd mscorlib:0:in `Throw': Unable to translate bytes [B8] at index 2 from specified code page to Unicode.

Right, the installer installs only to GAC. You can download all the binaries from [http://ironruby.codeplex.com/releases/view/49097#DownloadId=159562.There](http://ironruby.codeplex.com/releases/view/49097#DownloadId=159562.There) is no point copying them to Program Files. Once they are in the GAC all apps load them from there. You can build a redistributable msm Windows installer package if you want to include IronRuby in your Windows app or you can just grab the binaries from the link above if you want an xcopy deployment. It seems irb doesn’t like the command you’re writing … does it include non-ASCII characters?

I’m not writing any characters, I’m just running iirb from the command line… On Tue, Oct 26, 2010 at 3:52 PM, Tomas M. \< ---

Hi, I got a similar error after performing a clean install of IR 1.1.1 with the Visual Studio Tools under XP SP3 (Swedish with MUI), and might have a workaround (see below).

Hmmm, same problem here after installing 1.1.1 (after a previous 1.0 install). I tried resetting sizes and still no success. It would be neat to have this work 🙂
