How can i fix it ? Thx

Depending on your system, can you try your_package_manager(brew, apt-get, yum, ...) install zlib and retry installing it ? I'd also recommend you to use a Gemfile to manage your dependencies, but that's up to you and shouldn't change anything to this issue.

[jonathanulco]

I've tried with zlib-bin but no change. I will try gemfile. Thx

[Jerska]

Can you try with zlib-dev or zlib-devel too ?

[jonathanulco]

I didn't find zlib-dev but i found zlib1g-dev

Before reporting this, could you check that the file you're documenting
has proper syntax:

  /usr/bin/ruby1.9.1 -c lib/record_extractor.rb

RDoc is not a full Ruby parser and will fail when fed invalid ruby programs.

The internal error was:

    (RDoc::Error) unknown type of %string "i"

ERROR:  While generating documentation for algoliasearch-jekyll-0.5.3

[Jerska]

Seems like we're making some progress. It seems like you're using ruby 1.9.1 , could you try with the latest version?

[Jerska]

Actually, it seems like it's the documentation installation that failed, I'm not sure wether gem rollbacks on error or not, you might be able to use the gem anyway.

Ok thx have a nice day.
