Thanks Sean. Changing the def zipped\_stream(entry)Method fixed the  
problem.

I had found a post from someone else having this problem in Capistrano  
but they were able to get round it by updating Gems, but that didn’t  
work for me.

Your help is much appreciated.

Sharon

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  
Jamis:

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) entry.read(10) # skip the gzip header zis = Zlib::Inflate.new(-Zlib::MAX\_WBITS) is = StringIO.new(zis.inflate(entry.read)) ensure zis.finish if zis end

Cheers,

Sean
