Installation Issue

Hi,

First of all, I have been searching through the forum to try to resolve
this problem.

I’m walking through some tutorials from lynda.com and after I issue the
command “rails my_app”, everything seems to go fine. I am able to
browse my application on WEBrick via http://localhost:3000.

However, if I click on the RoR-generated “About your application’s
environment” (under “You’re riding Ruby on Rails!”, I get the following
error message:

“We’re sorry, but something went wrong. We’ve been notified about this
issue and we’ll take a look at it shortly.”

This error was first found after I added a simple controller and view to
my project and attempted to browse to http://localhost/say/hello --> I
got the same error.

The first thing I did was to stop the IIS 7 service then restart WEBrick
but that didn’t help.

I then checked the development.log which led me to this post:
http://www.ruby-forum.com/topic/136133

So, I deleted the entire project and recreated it by using “rails -d
mysql my_app”. Same problem. I then tried “gem install sqlite3-ruby”.
That didn’t help either.

As of now, this is where I stand.

I’m really hoping someone can help me. I’m trying to work through these
tutorials but am stuck because of something I (obviously) don’t
understand.

Thanks in advance for your help and time.

Disregard. MySQL 5.1 is not compatible.

See this blog post on instructions for setting up RoR on Win7

Hi

First you have to install the mysql adapter gem issue at console

sudo gem install mysql

And also you have to specify database connection settings in
config/database.yml
