Nokogiri compatibility issue with Ruby 2.4 on windows

[nahmad2017]

Nokogiri version 1.7 is not compatible with Ruby 2.4 on windows. An update to Nokogiri (Nokogiri 1.8.0) was planned to be released but it is not released so far.

So we can track this more effectively, that's this issue on the Nokogiri Issue Tracker.

nokogiri 1.8.0 is released. I updated the gemfile and bundle install succeeded. Now , when I try to run instiki , I get another error "Couldn't load Eventmachine C Extension"

Googling around, the remedy for that error seems to be

gem uninstall eventmachine

followed by

bundle install

Not sure what you would do if you have other ruby program which rely on the installed eventmachine gem.

[nahmad2017]

This doesn't seem to work.

As a workaround, does

gem 'puma'

instead of

gem 'thin'

in the Gemfile fix the problem (IIRC, puma does not rely on eventmachine, whereas thin does)?

[nahmad2017]

It says can't load redcloth_scan (Missing source file)

Something seems to be pooched in your installation. Extensions installed via bundle install don't seem to be found when you actually try to run Instiki.

We can work around each of them, 1-by-1, but eventually, we will either tire of the process or hit a wall.

What's your setup? (What Ruby, etc, ...?) And can you, for instance, install gems manually?
