but

Not sure but it seems that nokogiri and 2.3 is not fully supported yet by Rails on Windows.
Any way, I tried to install the latest version on Windows 64-bits and ruby 2.3:

gem install nokogiri -v 1.6.8.rc3 -N

and it was installed successfully:

Fetching: pkg-config-1.1.7.gem (100%)
Successfully installed pkg-config-1.1.7
Fetching: mini_portile2-2.1.0.gem (100%)
Successfully installed mini_portile2-2.1.0
Fetching: nokogiri-1.6.8.rc3-x64-mingw32.gem (100%)
Nokogiri is built with the packaged libraries: libxml2-2.9.3, libxslt-1.1.28, zlib-1.2.8, libiconv-1.14.
Successfully installed nokogiri-1.6.8.rc3-x64-mingw32

But when trying to install rails it failed:

gem install rails -N
ERROR:  Error installing rails:
        nokogiri requires Ruby version < 2.3, >= 1.9.2.

Already supported... after long time wait

@Sega100500 I meant

that nokogiri and 2.3 is not fully supported

i.e. Nokogiri with Ruby 2.3. You can even try to install rspec-rails on Ruby 2.3 to see the same error of nokogiri Ruby version.

@javix
Ruby 2.3 + nokogiri
On Linux it work, on windows - no

[larskanis]

Ruby-2.3 cross build targeting Windows RubyInstaller was added in this commit . Please try the latest pre-release:

gem inst nokogiri --pre

or per Gemfile:

gem 'nokogiri', '1.6.8.rc3'

The installation from source should work as well (with nokogiri-1.6.7):

gem inst nokogiri --platform ruby

@larskanis Thanks very much 👍 Perfect timing.

[Sega100500]

@larskanis
Fine. But how about gem update?
Install nokogiri of specific version - is not problem. Problem is when nokogiri update it fail installation.

[okeyparking]

A quick workaround is the following (ruby 2.3 win64):

gem install nokogiri -v '1.6.6.4'
gem install rails 
gem install nokogiri -v '1.6.8.rc3'

After that explictly include
gem 'nokogiri', '>=1.6.8.rc3'
in gemfile

gem update works without error
bundle install and bundle update works too

@okeyparking
It work! Many thanks!

As mentioned above, windows is supported in the prerelease and will be in 1.6.8 final.

@okeyparking

I'm totally new to this, could you tell me how to:

After that explictly include
gem 'nokogiri', '>=1.6.8.rc3'
in gemfile

[zuckerlinh]

Same question as Zbromination, Plz explain

After that explictly include
gem 'nokogiri', '>=1.6.8.rc3'
in gemfile

[belgoros]

@okeyparking, @zuckerlinh: Hey, guys, just add gem 'nokogiri', '>=1.6.8.rc3 in your Rails application Gemfile (outside of the development, test, production group) and run bundle update nokogiri.

Yes. It works. Thanks. :)
