Hi,

I’m running ruby 1.8.5 (2006-08-25) [i686-linux]

I tried:

gem update --system

And, at the end of the install, got the following error:

Successfully built RubyGem  
Name: sources  
Version: 0.0.1  
File: sources-0.0.1.gem  
hook /opt/lib/ruby/gems/1.8/gems/rubygems-update-0.9.2/./post-install.rb  
failed:  
undefined method `post\_install\_message’ for  
#Gem::Specification:0x49ba176c  
Try ‘ruby setup.rb --help’ for detailed usage.  
RubyGems system software updated

Now, subsequent invocations of `gem` produce the following error:

gem list --remote \> gems.txt  
ERROR: While executing gem … (NoMethodError)  
undefined method `refresh’ for #Hash:0x55d0d2d4

gem update --system  
Updating RubyGems…  
ERROR: While executing gem … (NoMethodError)  
undefined method `refresh’ for #Hash:0x5364d414

Anyone else experienced this?

I’ll try reinstalling rubygems from source…

Regards,

Bill

Something has gone bonkers with your source cache. Mine is in  
~/.gem/source\_cache on OS X. Remove that and you should be able to  
work again.

Rats… the reinstall from source appeared to complete without  
errors, but I still get:

gem list --remote \> gems.txt  
ERROR: While executing gem … (NoMethodError)  
undefined method `refresh’ for #Hash:0x4edb22b8

Thanks Austin, that fixed it!

(Mine was in: /opt/lib/ruby/gems/1.8/source\_cache )
