Error during bundle install

[paulioceano]

The bundle install run throws an error regarding the Ruby version required for the gem Nokogiri.

Even when the ruby version installed is 2.4.4, still request for version 2.4.*-

Apparently, there is a version issue with that gem (sparklemotion/nokogiri#1618).

According to this, the issue was solved with Nokogiri version 1.8.0

Hello @paulioceano,

is this when running bundle install directly on windows?
Can you paste the relevant section of the output here?

I tried updating Nokogiri dependency to 1.8.0 but that doesn't seem to work, as Rails depends on Nokogiri 1.6.x.

I could try using a version that is >= 1.6.0 and < 1.6.8, but I don't know if you would still get an issue on Windows. Can you try that out yourself, by following these steps?

1. Add this line to Gemfile: `gem 'nokogiri', '= 1.6.0'``
2. Run bundle update nokogiri

Also, can you please try this out on Ruby 2.5?

Hi @albertoperdomo .

Yes, this error happens when running ´bundle install´ directtly on windows.
This is the output:

Fetching nokogiri 1.6.8 (x64-mingw32)
Installing nokogiri 1.6.8 (x64-mingw32)
Gem::InstallError: nokogiri requires Ruby version < 2.4, >= 1.9.2.
An error occurred while installing nokogiri (1.6.8), and Bundler cannot
continue.
Make sure that `gem install nokogiri -v '1.6.8'` succeeds before bundling.

In Gemfile:
  rails was resolved to 5.0.0.1, which depends on

After adding the line gem 'nokogiri', '= 1.6.0' to the Gemfile got this error:

Can you please open the URL in the output and follow the instructions (or some other tutorial) to install nokogiri? Then try again with that line gem 'nokogiri', '= 1.6.0'?
