Solution 2

to answer my own question:

the fix was to delete all the contents from 

vendor/cache

after that it worked.

clearly a bundler bug.

OTHER TIPS

I was having similar problem with bundle upate (bundler 1.0). I am using rvm with gemset for my application.

Solution was to remove:

~/.rvm/gems/ree-1.8.7-2010.02@gemset-name/cache

Allegedly, the original issue is fixed with Bundler 1.0.x, but I still had the same error message (using 1.0.3). I removed all cache folders, including in RVM directories, as outlined in the other answers here -- no dice.

It turns out you'll also get this error if Bundler can't resolve one of your sources (i.e., those returned by $ gem sources). Even if you list multiple sources, it will ping all of them, and if any source is bad, it will crash with this nondescript 'initialize': not in gzip format error.

As described in this ticket, that can be because of something like an inaccessible VPM or local network source, but I actually ran into the problem due to my company's firewall blocking rubygems.org.

Just submitting this answer as another possible solution to clear up this vague error message.

just happened to me with bundler 0.9.26 and rails3 beta4. launched

bundle package

now it works. but if I remove vendor/cache the problem persists.

Had the same thing, removed /bundler_gems/cache

Even though I'm running Bundler 1.0.0, I still hit this error. bundle install didn't work, but running bundle package did.

rm -rf vendor/cache

bundle package

bundle install

bundle lock

It's a bit annoying... I don't know why I can't do bundle install --relock

If you're using Capistrano with Bundler's require 'bundler/capistrano', the cache directory is at shared/bundle/ruby/1.8/cache.

All traces of this error went away when I upgraded to Bundler 1.0.x.

I've solved this issue in a rails 3.1 app by deleting the archived gem files:

$ bundle -v
Bundler version 1.0.17
$ rm -f vendor/bundle/ruby/1.8/cache/*.gem

I ran into this problem when deploying, but didn't want to remove vendor/cache from git.

Instead, I ended up doing this:

# deploy.rb
namespace :bundle do
  desc "Removes vendor/cache when NO_GEM_CACHE=1 is set. Resolves Zlib::GzipFile::Error (not in gzip format)."
  task :remove_cache do
    run "rm -fr #{release_path}/vendor/cache" if ENV['NO_GEM_CACHE'] == '1'
  end
end
before :'bundle:install', :'bundle:remove_cache'

Whenever this error crops up simply:

cap deploy NO_GEM_CACHE=1
