I upgraded RubyGems to 0.9.1 using Eric’s instructions here:

[http://blog.segment7.net/articles/2007/01/18/rubygems-0-9-1](http://blog.segment7.net/articles/2007/01/18/rubygems-0-9-1)

basically:

gem update  
gem pristine --all

but now I get this error:

gem update sexp  
Updating installed gems…  
ERROR: While executing gem … (NoMethodError)  
undefined method `refresh’ for #Hash:0x1055db4

I tried re-installing manually, downloading the archive and running  
ruby setup.rb all and get the same error.

system: macos 10.4.8, ruby 1.8.4 (2005-12-24) [i686-darwin8.6.1]  
Anybody have a clue about what to do?

Run these:

gem sources  
sudo gem sources

then send me a copy of your user (~/.gem/source\_cache) and system (/  
path/to/ruby/lib/gem/1.8/source\_cache) indexes.

Then delete both of those indexes.

My mail delivery was messed up so I didn’t notice that there was a  
previous thread on this topic.

I archived and then deleted:

/usr/local/lib/ruby/gems/1.8/source\_cache  
~/,gems/source\_cache

and gem install is now working.
