gems installation - invalid gem format

[Serguei Cambour]

No matter on which OS you are, - XP Family, XP Pro or Ubuntu 9.10. No
matter if you have firewall 'hyper-sensitive' or proxy. When trying to
do gem update --system or even when trying to install a new gem like
'gem install [gem_name] I always got the below error:
------------------------------------------------------
serge@serge-laptop:~$ sudo gem install heroku
ERROR: Error installing heroku:
invalid gem format for /usr/lib/ruby/gems/1.8/cache/heroku-1.4.gem

serge@serge-laptop:~$ ruby -v
ruby 1.8.7 (2009-06-12 patchlevel 174) [i486-linux]
serge@serge-laptop:~$ gem -v
1.3.5
I always get the above error of '...invalid gem format..'. Any idea how
to resolve that? Something goes wrong in rubygems
commits/dependencies?Thank you.

Does this break with any other gem? Or is it only the heroku gem?

With any other gem, even when I tried from installing Ruby, then doing
(On Windows or Ubuntu - it was the same):

gem update --system
Updating RubyGems
Updating rubygems-update
ERROR: While executing gem ... (Gem::InstallError)
invalid gem format for

Installing fromlocal rubygems-update-1.3.5 didn't solve the problem.
Only the error message changed. Instead of

invalid gem format for
C:/Ruby/lib/ruby/gems/1.8/cache/rubygems-update-1.3.5

I got

invalid gem format for C:/Ruby/lib/ruby/gems/1.8/cache/[gem_name]

Can you remove 1.8/cache folder and try again?

This time, please execute the install command using --debug -V
options, which will provide us enough information to see where the
problem is.

Thank you,

That means that you remove the cache gem folder? The gem list is only
going to display the installed ones.

Can you enter the following URL in your browser, download it to a
location and then try installing it?

http://gemcutter.org/gems/rubygems-update-1.3.5.gem

The downloaded file should weight 279K.

then, from the command line where you downloaded that file:

gem install rubygems-update-1.3.5.gem

If doesn't work, then you're behind a firewall or proxy that is
blocking all the Amazon S3 downloads and is downloading garbage that
RubyGems cannot install
