安装mysql或mysql2 gem时出现问题

Question

I have ruby version 2.0.0.0p195 (2013-05-14) [x64-mingw32] installed as well as ruby gem version 2.0.3 installed. I just recently installed MySQL Community Server 5.6.12 (32 bit) installer as well. I am trying to get the mysql or mysql2 gem to work and then get a server installed to learn more about Ruby on Rails.

When installing the mysql2 gem I get this error below, can anyone point me in the right direction to get mysql2 gem installed so i can use ruby on rails with mysql and then a web serer eventually.

Building native extensions. This could take awhile...

ERROR: Erorr intalling mysql2: ERROR: Failed to build gem native extension

Answer 1

I found the answer (for me) to be using rails installer and uninstalling my old ruby information. Rails installer includes ruby, rails and sqllite3. As well, then I installed WEBrick which runs off of localhost:3000. It allows me to have WAMP and Ruby/WEBrick. This isn't ideal since everything isn't running on one area, but is great for what I need it for which is learning and a side project I want to develop using HTML5 and/or Rails (a media application).
