Rails 3.0.3, rails_admin gem, generator not found

I am getting error installing Rails_admin with rails 3.0.3. Command line log shown below -

    C:\rorprj\app>gem uninstall rails_admin 
    Successfully uninstalled rails_admin-0.0.0


    C:\rorprj\app>gem install rails_admin 
    Temporarily enhancing PATH to include DevKit...  
    Successfully installed rails_admin-0.0.0 1 gem installed  
    Installing ri documentation for rails_admin-0.0.0...  
    Inst开发者_如何转开发alling RDoc documentation for rails_admin-0.0.0...


    C:\rorprj\app>rails generate rails_admin:install_admin 
    **Could not find generator rails_admin:install_admin.**

    C:\rorprj\app>rails -v 
    Rails 3.0.3

Anything I can do fix this?

Try this

gem 'rails_admin', :git => 'git://github.com/sferik/rails_admin.git'

Sometimes the actual github repo has an different version. I have it running on 3.0.3 and that is what is in my gemfile.

If you call

rails generate rails_admin

the 'help' returns

*Hello, to install rails_admin into your app you need to ru*n:

rake rails_admin:install

And this works. I just encountered the same problem as you. (Keep in mind that you need to add the gem to the gemfile too)

Did you add this gem to your Gemfile? This file is responsible for loading all gems that your application depends on, and if this gem isn't specified in it then it will not be loaded.
