So I was working on Rails and getting a bit frustrated with my user model so I destroyed it (I'm also using devise which may be a source of error). In my defense I was tired, frustrated, and a bit on the tipsy side. I tried to add it back in with a simple rails g scaffold user first:text last:text, but I get the following error when trying to generate the model. How do I fix this all back up?

Remove the line devise_for :users from routes.rb and try running rails g scaffold user first:text last:text. It should work fine.
The devise_for method expects User model to be present. Hence, it fails on loading the rails environment when you run the rails scaffold command
Maybe you have conflicts with naming conventions?
Try
rails g scaffold User first:text last:text
instead.
You are generating a model for the class User (Classes are Capitalized CamelCase in Ruby)

When I try to perform "rails generate devise:install" I get this error message:
I've tried re-installing the devise gem multiple times. This error also comes up when I try to start up my server. I'm wondering if the cause of this is from initially trying to install the devise gem with "rails generate devise install" instead of putting a colon between devise and install.

Could anyone help please? and feel free to correct me on how i'm asking the questions. New to this community and would love to be involved.

Welcome to Rails man.
I know the community is all up on the devise gem. The reality is that Devise is an advanced authentication app that's a gem.
If you're learning, and you need authentication, some super geek named Ryan Bates hooked you up with a tutorial and screencast on basic authentication that will work exactly how you need it, and you will understand what's going on:
http://railscasts.com/episodes/250-authentication-from-scratch
WHABAM!
Be mindful that is based on rails 3. Check the differences between rails, and ruby versions if you encounter problems while following directions. If you do get errors, still, this path will get your further to deploying that app of yours.
Come back to Devise when you need the features it provides, Rails, and confident you can implement ideas found in the book 'Crafting Rails Application' by José Valim. He's one of the main contributors of Devise, so you'll get insight on his thought process.
Bit new to rails, but I was generating some controllers, I did one, then went to do another and it spit out an error:
c:\row\dev\a>rails generate controller Person name:string
C:/row/ruby200/lib/ruby/gems/2.0.0/gems/actionpack-4.0.2/lib/action_dispatch/rou
ting/mapper.rb:229:in `default_controller_and_action': missing :controller (Argu
mentError)
I tried rubymine just to see and it pretty much just did the same thing, that full list of what it outputted is below. I've never had it just decide to stop generating controllers like that, and I did add something to the routes file because I saw a link that said the routes file might need root to: 'controller#action' though i've never had to include that in the route file to generate a controller before, but that didn't fix it either. That was the only other thing I could find online with a similar problem. Any thoughts?

For Generating a controller you specified with method name not variable
like
rails generate controller Person index show
I hope you understand and it work for you.
Thanks.
I was following the instructions at http://www.activeadmin.info/docs/0-installation.html#gemfile under the heading Register your models with Active Admin. Before adding the resource of Post I was able to start my server just fine. Once I added the resource of Post, it would no longer start. It was giving me an error about the I18n.config.enforce_available_locales needing to be set to false to prevent the error message. I found another Stack Overflow post which said to set this to false in the application.rb file. After doing this the message no longer shows in my Terminal interface, but the servers don't start.
Now I am getting the following output in Terminal when I run $ rails server

How to I initialize the Constant of Post?
My apologies if these errors seem obvious to some. I am still new to rails.
You have to have a Post model. Do this:
$ rails g model Post
$ rake db:migrate
When I try to run my rails server I get the following error (Important note: I have just pulled my code from Github to Nitrous.Io, and was starting to work on the application):

Looks like your database hasn't yet been created.
The most likely solution would be to run rake db:migrate if you're using sqlite, though if you're using Postgres or Mysql on Nitrous, you'll need to install them first. There is a guide to what's available here http://help.nitrous.io/categories/databases/
