I am using ruby 1.9.3 and rails 3.2.2. Every time i use the thin server with private_pub gem it does not work i did rackup private_pub.ru -s thin -E production. I get the following error

but it i include the thin gem in my gem file it would work fine. Any help thanks.
You can't start linux without linux.
You can't launch a rackup server without Rack.
You can't launch thin without thin gem.

from /home/dimas/RUBY/application/faye-tutorial/faye.ru:3:in `block in <main>'
I have the same problem. fix it with:
add this gem to Gemfile
gem 'faye'
gem 'thin'
then bundle install.
If you want to use a gem, it must be in your Gemfile. You can solve your problem as follows:
Add the following line to your Gemfile: gem 'thin'
Update your current app's environment: bundle install
Start the web server: bundle exec thin start

I changed my distro from Ubuntu to Elementary OS. I kept my /home directory, so that I don't have to install anything.
I followed GoRail's guide to install Rails.
Now when I try to re-install everything from the same guide, it turns out that RVM, Ruby and Rails are already there.

However, when I go to my old projects and try to start a server it throws the following error:

As per your error message
There was an error while trying to load the gem 'uglifier'. (Bundler::GemRequireError)
It seems you don't have NodeJS installed. Run
sudo apt-get install nodejs
bundle install
See "There was an error while trying to load the gem 'uglifier'. (Bundler::GemRequireError)".
Attempting to switch from WEBrick to Unicorn, I've got the Unicorn gem v 4.8.1 installed on my machine [via "gem install unicorn"] and it's also located in my Gemfile ["gem "unicorn", "~> 4.8.1"], for which I've successfully run bundle install.
However, when starting the server locally via "rails s" (worked fine pre-Unicorn), I get the following error:

I'm thinking this may be due to using RVM? When I type 'which gem "unicorn"' I get:
/Users/johndoe/.rvm/rubies/ruby-1.9.3-p392/bin/gem
/Users/johndoe/.rvm/gems/ruby-1.9.3-p392/bin/unicorn
Also for reference, my $PATH: /Users/johndoe/.rvm/rubies/ruby-1.9.3-p392/bin/gem:/usr/local/rvm/bin:/Users/johndoe/.rvm/gems/ruby-1.9.3-p392/bin:/Users/johndoe/.rvm/gems/ruby-1.9.3-p392#global/bin:/Users/johndoe/.rvm/rubies/ruby-1.9.3-p392/bin:/Users/johndoe/.rvm/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/usr/local/git/bin
"bundle show unicorn" gives: /Users/johndoe/Sites/my_app/vendor/cache/ruby/1.9.1/gems/unicorn-4.8.1
The application successfully deploys to Heroku, so I believe this issue is isolated to my machine (rather than being an issue with the application). Any ideas on how to solve this?
I seemed to fix the problem by uninstalling the gem via "sudo bundle exec gem uninstall unicorn", then reinstalling it via standard "sudo bundle install"
Still not sure exactly why the issue occurred, but that fix did seem to work.
Can you used this..
$ rails server unicorn
or
bundle exec unicorn -p 3000
Still not sure what caused this problem.
I solved this simply by reinstalling the unicorn gem.
gem uninstall unicorn
bundle install
bundle update
I am trying to start rails server as a daemon using the -d switch. I have installed thin server and working on Ubuntu. If it is started as a normal process, it works, but when using the -d switch, it complains of a server pid file /tmp/pids/server.pid
Even if I delete the file and try to start the server with -d switch, it won't start. Please help.

run the server using 'bundle exec' in the start like:

Alternatively, your exception trace is stating a mismatch for the activated daemons gem. To fix this, set the version of daemons gem to be greater than (instead of equal to) 1.1.8 and try.

Have you already installed bundler? If not, try:
gem install bundler
If so, try:
gem install bundler --pre
If you running Ruby version manager, what version are you running? You might be set to the wrong version of Ruby.
I think it would be easier for you if you used RVM or some other version manager.
if you have multiple versions of rubygems installed, uninstall all but the one you want to use.
I think rails 4 requires rubygems 2.x.
Also check the bundler version.

Compass was not installed. I issued the following per cimmanon's suggestions:
gem install compass
gem install compass-susy-plugin
gem install stitch

Also had to install java for compass-validate to work.
