On windwos, we could not find a way to execute
gem --version
on windows.
The weird thing is this is happening while we are able call ‘gem
–version’ on DOS directly.
Of course there is no problem on Linux.
Have you tried invoking gem as gem.bat --version in IRB? There’s a
special case in the config.gem installation code for win32, so I’d
guess that that might solve your problem…

Yes, I tried.
gem.bat itself is invoking but the calls it makes are resulting all in
errors.
Basically, in IRB, we could not call any “gem installed” commands in
Windows.
e.g. gem, rails, rake
The mystery is as they are available in Shell, why they do result in
error called from IRB?
So far 4 other people complained me of the same thing.
I am inclined to conclude that nobody uses IRB on Windows 
Could you provide more details on how gem “gets an error”? I just
tried it (including installing gems from IRB) and it worked fine. This
isn’t the first heisenbug that I’ve seen with Ruby and Windows… (for
instance, see
http://groups.google.com/group/rubyonrails-talk/browse_thread/thread/36be3d7767f66300/9b14c8774d0a5159
)
Thanks,

I discovered the problem after running a rails template on Windows.
After seeing the problem I opened IRB and failed to call rails, rake
and gem from there. Tried on a few other windows machines to fail the
same way. The error is “Invalid Exacutable Format”
You can try the template:
rails your_app -m http://tinyurl.com/cs-active-scaffold
Which is from the rails tutorial
http://conceptspace.wikidot.com/rails101:introduction
PS. I am an Ubuntu user. I am just trying to know how to keep cross-
platform
Now I understand. Yep, that’s a known issue with templates:

–Matt J.
If you successfully run
rails your_app -m http://tinyurl.com/cs-active-scaffold
on your windows then I would say that everybody I’ve met has a wrong
installation!

Relief to know that.
I added warnings to http://conceptspace.wikidot.com/ and debugged the
template to be free of commands almost. Finally I could achieve a
running Windows version I guess.
