Nokogiri requires Ruby version < 2.3

Question

I am trying to get Rails to work on Windows 10. I am using Ruby 2.3.0, and Rails 4.2.6, and am temporarily using Nokogiri 1.6.3.

When I try running rails new demo, it returns an error:

An error occurred while installing nokogiri (1.6.7.2), and Bundler cannot
continue.
Make sure that `gem install nokogiri -v '1.6.7.2'` succeeds before bundling.

When I run gem install nokogiri -v '1.6.7.2 I get:

ERROR:  Error installing nokogiri:
        nokogiri requires Ruby version < 2.3, >= 1.9.2.

How do I update Nokogiri and get Rails to work?

what does ruby -v output? – Claman

it seems just for windows, in linux it workds for 2.3.0 ruby – Cadel

It's a shame, but unless you want to try the release candidate approach, you'll need to downgrade your Ruby version. Another option would be to try JRuby, if that's not too drastic a thing for you. JRuby might be helpful in reducing the OS-specific issues Windows Rubyists might encounter. – Breastsummer

Answer 1

Install the newest version of Nokogiri. In Gemfile:

gem 'nokogiri', '~> 1.6.8.rc2'

Surbeck

It's not a command, it's a line for the Gemfile. After adding it you have to run bundle install. If you have bundler installed and just do a gem install, you will have two versions of nokogiri installed but the project will still use the old one. – Jedjedd

this does fix the issue, same version as poster, Win10, Ruby 2.3.0p0. can you explain what is causing the issue, and what this line does to fix it? – Broomstick

Answer 2

use bundle update nokogiri, but also check you ruby version ruby -v

Whelk

ruby -v : ruby 2.3.0p0 (2015-12-25 revision 53290) [x64-mingw32] bundle update nokogiri : This Bundle hasn't been installed yet. Run 'bundle install' to update and install the bundled gems. – Soidisant

Answer 3

Problem solved in version of Nokogiri 1.8.0.

Answer 4

I had the same problem as you. On Windows you need to perform an additional step:

Tarra

Yes, that's how I got the initial nokogiris but I need 1.6.7.2 specifically for it to work. In this case, when I use the gem, the same error occurs. – Soidisant

Answer 5

I recently ran into the same problem installing rails on windows with Ruby v2.4.1 I found that removing the gemfile line:

gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]

then running bundle update

then putting the tzinfo-data line back in the gemfile

I could then run bundle without any issue. All is working well again.
