I have been working on Ruby on Rails since 2 months go and now I want to change the database system so I installed the gem mysql2 by this command:
gem install mysql2 --platform=ruby -- '--with-mysql-lib="C:\mysql-connector\lib" --with-mysql-include="C:\mysql-connector\include" --with-mysql-dir="C:\mysql-connector"'
And It works!
but the problem is when I want to run rails server again I got this error
c:\zreactor\demo>rails server

I searched in the source and it looks everything ok,I have no idea why I got this error.
I'm working on W8 with ruby 2.0 and rails 4.0.2.
I would appreciate your help guys,
Thanks!
Most likely you need to regenerate libmysql.lib as described here:
...mysql2/mysql2.so: [BUG] Segmentation fault ruby 2.0.0p247

Check first if you can install libyaml:
on MacOS
or on Linux
Then gem install psych
Check out also rbenv/ruby-build issue 1251 and the GEM_HOME setting.
I'm just starting out with Rails and am following the Ruby on Rails essential training course and get problems trying to start WEBrick. Assuming it has something to do with my installation of mysql but not sure.
I made sure that I am in the correct directory (:C\sites\simple_cms)
I ran 'bundle install' before running 'rails s'
I followed these guides to get the gem installed (second to last entry): https://github.com/brianmario/mysql2/issues/372
I have ruby 2.2.1p85, rails 4.2.1 and this rubygem: mysql2-0.3.18-x64-mingw32 installed
Would appreciate some help from y'all :)

I'm trying to install and setup Jekyll as use it for github pages but is getting very complicated, I have to add that I just started programming few months ago so maybe I cannot see the mistake as easy.
Followed the instructions on website:
~ $ gem install jekyll
~ $ jekyll new myblog
~ $ cd myblog
~/myblog $ jekyll serve
# => Now browse to localhost:4000

Googling I found out that is necesary to install yajl-ruby gem, I do it, try again, same error so I try installing also gem pygments and win32-api but it keeps the same.
Also I tried to uninstall the current version 1.4.3 and installed the previous one 1.4.2 but the same problem appears.
Any thoughts?
If you are specifically aiming to use Jekyll with GitHub pages you can use their gh-pages Gem, which includes all the dependencies.
Try this install guide.
