Nokogiri 1.6.8 is an older release which references zlib 1.2.8. zlib 1.2.8 is no longer available for download from the zlib team as a supported release.

One option is to upgrade to nokogiri v1.7.1 which uses zlib 1.2.11. this version of zlib 1.2.11 is support and downloadable.

Another option is to use the precompiled version of nokogiri for the windows platform, rather than compiling everything with devkit. You should be able to do this by running:

gem install nokogiri

or, if that's trying to compile things, try

gem install nokogiri --platform mingw32

More details can be found in the installation tutorial: http://www.nokogiri.org/tutorials/installing_nokogiri.html

Good luck!

Dear Sir,

nokogiri v1.7.1 needs ruby version 2.1.0 and I can't my ruby version because of some reason.

Is there any other way for using nokogiri v1.6.8 gem .

Please find error.

D:\LX_release7_branch_new\gems>gem install nokogiri-1.7.0.1.gem
ERROR: Error installing nokogiri-1.7.0.1.gem:

In the final command you run, you need to specify the version of the gem that you want to install. Try

gem install nokogiri --platform mingw32 -v 1.6.8

[jaishanker123]

Dear Mike,

I am still getting below error for command "gem install nokogiri --platform mingw32 -v 1.6.8".

@jaishanker123 this will be addressed in nokogiri 1.8.0. in the meantime please consider upgrading to 1.7.1 or 1.7.2. Or else, don't use ruby devkit and use the precompiled binary gem.
