Forum: Ruby Zlib Error in ubuntu while installing new gems

Hi,

After installing the rubygems 1.3.1, I face the following issues while
installing new gems.

Error:

arun@mysystem:~/Desktop$ sudo gem install ip2country-0.0.2.gem

ERROR:  While executing gem ... (Zlib::GzipFile::Error)
    not in gzip format


My Environment:

OS -  ubuntu  8.04 - the Hardy Heron version.

Ruby -  ruby 1.8.6 (2007-09-24 patchlevel 111) [i486-linux]

RubyGems Environment:
  - RUBYGEMS VERSION: 1.3.1
  - RUBY VERSION: 1.8.6 (2007-09-24 patchlevel 111) [i486-linux]
  - INSTALLATION DIRECTORY: /usr/lib/ruby/gems/1.8
  - RUBY EXECUTABLE: /usr/bin/ruby1.8
  - EXECUTABLE DIRECTORY: /usr/bin

  - GEM PATHS:

Please suggest a solution. I want to install required gems. Do i need to
revert my rubygems version? because in my older version rubygems-1.0.1,
i dont see any errors. is it a bug in rubygems-1.3.1 or do i need to
change anything?

Thanks,

Arun.

did you apt-get install the ruby zlib libs?

Yes I did, but still it throws the error. If i use rubygems-1.0.1, then 
i found no problems in installing gems. Its working well with 
rubygems-1.0.1.

I'd try rebuilding all from scratch, or just stick with gems 1.0.1 :)
There may have been some difficulty from an upgrade from 1.0.1 to 1.3.1 
maybe it kept behind old cached [somehow bad] files?
