First a little indication of what I’m running:

I’ve created a new rails project called simple_cms under C:\Users\Dean\Documents\Ruby_Projects\ .

I then navigate into the project directory, so my path then is C:\Users\Dean\Documents\Ruby_Projects\simple_cms\

I then run (with my administrator command prompt)

rails server

but I then get a whole lot of errors but the most prominent one being:

The specified module could not be found some\path\mysql2\1.9\mysql2.so

Any ideas?

EDIT: Attached is my full command prompt output…

It looks like your mysql2 gem hasn’t been installed correctly.
