I'm having a problem upgrading from 0.6.1 to 0.6.2 on my local (Windows
XP) test machine.  I have tried this on a couple of Windows machines and
each time I get a (Zlib::BufError) buffer error.

On my local machine I have updated Ruby to version 1.8.6 and have
updated Ruby Gems to 0.9.4. I have also tried a clean install of Ruby,
Gems and Radiant on a newly formatted machine, but again get the buffer

Any help would be appreciated.



C:\>gem update radiant

There was some discussion of this problem on the Capistrano mailing
list too. Apparently, it's a bug in RubyGems.  Here's the fix, from

P.S. If you are on a Windows machine, and you get Zlib errors trying
to install the Capistrano gem, try this. Find the rubygems/package.rb
file (wherever it happens to be in your Ruby installation), open it
up, and find the zipped_stream method. Then, replace it, wholesale,
with the following:

 def zipped_stream(entry) # skip the gzip header
   zis =
   is =
   zis.finish if zis
