Strange Gem Problems


#1

Hey all,

I’m trying to add to install the program Bangkok as a gem, but every
time I try I get this error.

sudo gem install bangkok
/usr/local/lib/ruby/site_ruby/1.9.1/rubygems/package.rb:10:in require': no such file to load -- zlib (LoadError) from /usr/local/lib/ruby/site_ruby/1.9.1/rubygems/package.rb:10:in<top (required)>’

I’ve tried reinstalling the latest version of Gems, but it didn’t seem
to help. Any ideas? Thanks!

no such file to load – zlib (LoadError)

nothing is wrong with your rubygems. you don’t have zlib in your ruby
install.

Dang, how can I fix this?

It depends on your OS/distribution. On Ubuntu/Debian install the
package zlib1g-dev, (which contains the header files ruby’s zlib
extension needs to build properly) then re-configure, make and make
install your ruby-1.9 which it looks like you installed yourself from
source. Then reinstall rubygems. Other systems will name the package
with zlib header files differently, but otherwise instructions are the
same.
