Errors when Generating Devise Views - ruby-on-rails

I am developing a rails 3 application and I am using Devise for authentication. Everything seems to be working just fine, but when I try to generate the views using rails generate devise:views, I get a bunch of errors like this:
/Library/Ruby/Gems/1.8/gems/bundler-1.0.2/lib/bundler/shared_helpers.rb:2:in `require': no such file to load -- rubygems (LoadError)
from /Library/Ruby/Gems/1.8/gems/bundler-1.0.2/lib/bundler/shared_helpers.rb:2
from /Library/Ruby/Gems/1.8/gems/bundler-1.0.2/lib/bundler/setup.rb:1:in `require'
from /Library/Ruby/Gems/1.8/gems/bundler-1.0.2/lib/bundler/setup.rb:1
My default template engine is HAMl and I have the hpricot gem installed (as it says to do on the Devise github page).
Any ideas?
Thanks

Give it a shot with bundle exec:
bundle exec rails g devise:views

It turns out that it had something to do with my gems being stored in a different location than ruby. I'm not sure why it suddenly became a problem with that particular command. But re-installing rubygems seemed to do the trick.

Issue With Starting Rails Server & Creating a New Rails Project

I am new to rails and have finally been able to install rails and follow along with a video tutorial. I am having a couple issues. Yesterday I was not having any major issues. Then this morning when I tried to create another rails project I get an error or when I try to run my rails server for my last first project I get an error. Any help would be greatly appreciated. Thank you!

It looks like you don't have Rails installed on that environment. You may have installed Rails system wide, but since you are using RVM and you are within a Rails folder, you may be missing that specific Rails version.
Run bundler from within the Rails folder and install the required version.
$ bundler install
or simply
$ bundler
Navigate to your root directory cd ~ and type the following:
sudo gem install rails

Rails - script/server boot up

Can someone help me out with something seemingly simple? My newness to Ruby on Rails is the reason, no doubt. I cannot start up the server. It looks like the boot file cannot be located but I'm nor sure at all.
There are several versions of ruby here, related to installing rvm:
which -a ruby
/Users/me/.rvm/rubies/ruby-1.9.3-p327/bin/ruby
/Users/me/.rvm/bin/ruby
/usr/local/bin/ruby
/usr/bin/ruby
Probably need to remove some?
Using Rails 3.2.9 with Ruby 1.9.3 on a Mac Mini
Thanks!
cd [rails project dir]
$ script/server
/Users/me/.rvm/rubies/ruby-1.9.3-p327/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require':
cannot load such file -- script/../config/boot (LoadError)
from /Users/me/.rvm/rubies/ruby-1.9.3-p327/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
from script/server:2:in `'
This isn't the issue you are getting. script/server still works, what you are experiencing is an issue with the gems you are trying to use. What you might try is running rails s --trace, see what gems are causing the issue and manually reinstalling them. From the looks of it, it's just an issue with a lone gem with dependencies in 1.9.1.
With Rails 3+ you get access to the rails command line scripts so instead of calling script/server you just run rails server or rails s for short.

`require': cannot load such file on running rails --help on brand new install

This is getting quite frustrating. I've eventually resorted to completely removing RVM, and reinstalling from scratch, as a normal user, so restricted to my /home.
After reinstall, I've run gem update --system and gem install rails.
Then I run rails --help, and get the following error:
rails --help
/home/anthony/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- /home/anthony/config/boot (LoadError)
from /home/anthony/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
from script/rails:5:in `<main>'
Apparently rails thinks it should be loading a file /home/anthony/config/boot. It looks like the load path is screwed.
I've searched this out, and most people getting this error solve it with gem update --system (which I've one as above), or can at lest run rails -- or rails new . None of these work.

Please help!
This may be totally a red herring, but it looks like your rails is in a different gemset - "campingground" - than either gem or ruby, which are in your default gemset. I'm not sure if this will cause the issue you're seeing or not - I believe it's OK if you're using the campingground gemset rvm use ruby-1.9.3-p0#campingground, but not if you're using the default gemset rvm use ruby-1.9.3-p0 because I believe that gemsets all inherit the default gemset, but not vice versa. I've had some issues with the bin launchers of ruby helpers (like the rails command) barfing all sorts of confusing load errors, which are often this very issue. Again, not sure if helpful, but I'd share that shot in the dark.

Kaminari gem doesn't seem to install

I added "gem 'kaminari'" to my gemfile and ran bundle per the instructions, and it looked like it installed, but I'm getting errors like 'current_page' method not found messages. The documentation indicates that there should be a kaminari directory created in my app/views directory, but there isn't one. I'm using rails 3.0.7. Is there a different/better way of installing this gem?
Thanks
Could you have forgotten to run the generator?
rails g kaminari:views default
That should create your kaminari directory.

Why does Ruby "script/generate" return "No such file or directory"?

I am having trouble using script/generate. I am following the tree based navigation tutorial, which says to use script/plugin install git://github.com/rails/acts_as_tree.git or script/generate nifty_layout.
I keep getting:
No such file or directory -- script/plugin
I've tried these variations:
script/generate nifty_layout
rails generate nifty_layout
ruby script/generate nifty_layout
ruby generate nifty_layout
and they all tell me:
-bash: script/generate: No such file or directory
Am I missing something? Total ruby nuby here and I just can't seem to find an answer.
edit: rails 3 on Mac OS X 10.6
Rails 3 is your problem (or rather the cause of). Since rails 3 all of the "script/whatever" commands have been replaced with "rails whatever".
So now you want "rails generate ..." or "rails server" instead.
Be sure to watch version numbers or post dates when looking at tutorials :)
linkage:
Missing script/generate in Rails 3
There is a LOT of out-of-date information on the interwebs for Rails now as a result of it evolving quickly and being so popular. I use the Ruby on Rails Guides as my first stop for information as those pages seem to be the most current.
The rails generate info seems current.
you may try a couple things, first, make sure since you are using rails 3 that you have run 'bundle install'. depending on how you installed rails and which version of bundler you are using, it may not be finding your rails binary to execute the rails generate .. so you may try prefixing it with bundle exec rails g but that is deprecated and you should get a warning if you call it. Also, make sure you are following ryan's instructions for rails 3 (and run bundle install once you add to the gemfile) on his library: https://github.com/ryanb/nifty-generators
As a shortcut to rails server, you can use 'rails s'. Similarly for the console, 'rails c'.
