Cannot install thin on windows

Question

Hi guys,

I cannot install thin gem on windows. Something happen during build of native extensions.

Do anybody face same issues?

Here is the stack trace:

>gem install thin --no-ri --no-rdoc

Answer 1

Try the running the following

gem install thin –ignore-dependencies

If it fails retry installing rack and eventmachine and then re-running the above command.

gem install rack
gem install eventmachine -l
gem install thin –ignore-dependencies

Answer 2

this might help

$ gem install specific_install
$ gem specific_install -l http://github.com/eventmachine/eventmachine.git

Answer 3

First, install the DevKit from the RubyInstaller for Windows website (which it appears you have already done).

Then install eventmachine separately from the git repository as Roger shows.

You should then be able to install thin from the gem.
