'gem update' making wrong choice

ruby-talk
1

I work on a Win box, without compiler.
But 'gem environment' gives two PLATFORMs, win32 *and* ruby.
Then 'gem update' try to load the wrong gem...

How may I clean the environment variable ?
Thanks for help...

I don't think understand your problem.

gem env reports two platforms: that is correct: take for example this
linux box:

RubyGems Environment:
  - RUBYGEMS VERSION: 0.9.5 (0.9.5)
  - RUBY VERSION: 1.8.6 (2007-09-24 patchlevel 111) [i686-linux]
  - INSTALLATION DIRECTORY: /usr/local/lib/ruby/gems/1.8
  - RUBY EXECUTABLE: /usr/local/bin/ruby
  - RUBYGEMS PLATFORMS:
    - ruby
    - x86-linux
  - GEM PATHS:
     - /usr/local/lib/ruby/gems/1.8

That means rubygems will try to install gems marked with 'ruby' (also
known as pure ruby gems) or gems that are pre-compiled / binary or
specific for the x86 linux platform.

In your case, x86-mswin32 is a correct platform and RubyGems will try
to install the best gems for you.

What is the output you're having?
More information will be helpful to point directions or bug reports.

Yes Michel, this was reported and solved for gems marked as 'mswin32'
platform which extend to mongrel, rcov and others.

This problem was discussed on RubyGems development list and this was
fixed in the repository. I guess RubyGems developers are waiting for
more feedback until drop 0.9.5.1 bugfix release.

I'll suggest checkout the repository trunk of RubyGems [1] and perform
the install manually.

I must agree this should have rolled sooner, but catching all the odd
cases with so many platforms is a hard task.

Also, this is a mistake that gem developers used 'mswin32' instead of
using Gem::Platform::CURRENT (almost all, including me).

You can overide that for the time being with:

gem update --platform 'mswin32'

Maybe now 0.9.5 is out, we should start creating _correct_ packages
for it?

Thanks a lot, Luis. I tried the "correct" form --platform x86-win32-60
and it did not work. I understand now why...

All the best

Gems with string platforms can no longer be built on 0.9.5. The author will need to make changes to the gemspec, and the exception given should be straightforward.

Thanks a lot, Luis. I tried the "correct" form --platform x86-win32-60
and it did not work. I understand now why...

Just out of curiousity, how many incorrect options are there? Is this
totally idiot-proof in the new version? I'd be up to write a

gem help windows

docs patch with some simple overview of stuff like that, except my
Windows box is in storage. Deep storage. Practically cryogenic.

$ gem help platforms
[...]
When building platform gems, set the platform in the gem specification to
Gem::Platform::CURRENT. This will correctly mark the gem with your ruby's
platform.

Is that good enough?
