Hi all,

I’m new to Rails, I know this is a classic error, but I cannot resolve  
it anyhow ☹

This is my system config:  
Windows XP SP2  
Ruby 1.8.2 → installed using windows installer version  
Rails 1.0.0  
MySql 4.1.10

I followed the instruction on [rubyonrails.org](http://rubyonrails.org), exactly step by step.  
But the error occur everytime I tried to generate scaffold or generate  
model.

I tried to googling around, I tried to reinstall Ruby’s mysql library  
using gem, but it failed.

Help anyone? I’m totally stuck here ☹

Can you connect to mysql in other ways?

Did you set up a table?

Are you using new or old style hashed passwords in mysql (must be new  
style)?

What instructions are you following?

You’re not offering much in terms of information.

How are you invoking script/generate? What tables do you have in your  
db? Did you edit  
your database.yml appropriately?

Hi all,

Thanks for Craig and Ben, I solved the problem 🙂

I use PHP4 for main web development language, and I changed hashed  
password for MySQL to the old one long time ago. So that’s where the  
problem lies…
