So I want to deploy my app to Heroku, registered the account and did other necessary things. But I ran on a problem running command heroku keys:add. Here's the errors I get:

Help me out please!
PS! I am learning RoR using this book:
http://ruby.railstutorial.org/ruby-on-rails-tutorial-book#sec:install_rubygems
Solution here
It looks like this is a fairly common problem on Ubuntu. From this post on another forum:
On my system Ubuntu (Hardy 8.04) I
required libncurses5-dev and
libreadline5-dev (installed with
apt-get install . Re-run
"ruby extconv.rb" and it will show you
whether anything else is missing, or
create a makefile. Once you have your
makefile, run make, then make install.
Using rvm solved all the problems.
Install RVM with ruby:
$ \curl -L https://get.rvm.io | bash -s stable --ruby
Additionally with rails:
$ \curl -L https://get.rvm.io | bash -s stable --rails
$ gem install heroku
$heroku login

run gem cleanup it should solve the problem
This happened to me I fixed it by doing this:
First list your gems gem list
...
pg_search (0.7.9)
polyglot (0.3.5)
posix-spawn (0.3.10)
power_assert (0.2.2)
psych (2.0.5, 2.0.0)
pygments.rb (0.6.2)
rack (1.6.0)
rack-cache (1.2)
rack-protection (1.5.3)
...
Where you see psych, try using psych 2.0.5 gem uninstall psych -v 2.0.0
If you get an error message than uninstall gem 2.0.5 instead gem uninstall psych -v 2.0.5
Try Jekyll. This worked for me. You need to find the version of psych that interacts with your Ruby setup correctly. In my case was 2.0.0 but could be different for you.
Try bundle exec jekyll serve in some cases this will solve your issues.

Delete the folder ~/.cocoapods/ with rm -rf ~/.cocoapods
Enter pod setup command in Terminal.
This process will take time as this command clones the CocoaPods Specs repository into ~/.cocoapods/ on your computer.
It sometimes occurs when using a wrong apostrophe character in a Podfile or in a Podspec
Those apostrophes are default when using standard TextEdit app on OS X. I prefer Sublime Text to avoid such errors

rm -fr ~/Library/Caches/CocoaPods && \
gem update --system && \
gem update && \
gem cleanup && \

Having an issue running the "Thin" web server. It looks like installation was successful but when I run "thin start" It appears as though Thin starts to initialize but then cannot find some resources it needs.
Below, is the audit trail from my terminal session. Can someone offer a hand with this? According to the Thin docs, installation was done correctly. Thanks

You seem to install thin separate from rails
Add it to your gemfile and you should be fine
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
Then start server
Try to execute the following command:
cd to/your/rails/app
echo 'gem "thin"' >> Gemfile
thin start

Any ideas on what I could be missing?
Thanks so much. My clients site is down right now so any help soon would be appreciated.
UPDATE
When I run rake tasks I get this:
Could not find cache store adapter for memory_store (no such file to load -- active_support/cache/memory_store)
I saw this error recently when a shared host moved an application to a new server. I ended up blowing away the application's bundle and reinstalling it, and it seemed to work.
I use Capistrano for deployment, so if you use something else, YMMV. If your application root is this:
/home/jeff/myapp/
with the following subdirectories:
/home/jeff/myapp/current
/home/jeff/myapp/releases
/home/jeff/myapp/shared
the gem bundle is here:
/home/jeff/myapp/shared/bundle
Then I did:
rm -rf /home/jeff/myapp/shared/bundle
then
cd /home/jeff/myapp
bundle install
Once I did this, it seemed to work for me.
I have installed thin and try to do thin start, which end up with this error

Can someone help me out please, thanks in advance
the output denotes a directory called 1.9 i.e.
<ruby_install_dir>/lib/ruby/gems/1.9.1/gems/thin-1.2.8-x86-mingw32/lib/1.9/
Note: My thin version is 1.2.10. In the following i will use the path as it appears on my system.
For some reason the thin gem doesn't come with this directory. But a file called thin_parser.so resides in the parent directory <ruby_install_dir>/lib/ruby/gems/1.9.1/gems/thin-1.2.10/lib/
So my first solution was to create a directory 1.9 and copy the file thin_parser.so to it.
Now thin start works for me.
Alternatively you can edit the file <ruby_install_dir>/lib/ruby/gems/1.9.1/gems/thin-1.2.10/lib/thin.rb and change
if Thin.win?
# Select proper binary under Windows
major_ruby_version = RUBY_VERSION[/^(\d+\.\d+)/]
require "#{Thin::ROOT}/#{major_ruby_version}/thin_parser"
else
require "#{Thin::ROOT}/thin_parser"
end
to
if Thin.win?
# Select proper binary under Windows
major_ruby_version = RUBY_VERSION[/^(\d+\.\d+)/]
require "#{Thin::ROOT}/thin_parser"
else
require "#{Thin::ROOT}/thin_parser"
end
or even simpler
require "#{Thin::ROOT}/thin_parser"
I'm not sure what workaround is the better one, since i don't know what else files thin expects in the not existing directory. I don't know either where the Thin.win? fork becomes important.
I decided in favor of the first solution. But both ways fixed the Problem for me.
Best regards,
Tim
I ran into this same error when running rake db:migrate (I suspect thin start would have given me the same error.)
I'm running on Amazon Linux (rpm based, so similar to CentOS and Redhat). I had previously installed thin as root (gem install thin). Although it may be irrelevant to your situation, just for completeness, I had also installed eventmachine using:
gem install eventmachine --platform=ruby
Here is the error I got:
% rake db:migrate
rake aborted!
LoadError: cannot load such file -- thin_parser
/home/rails/.gem/ruby/1.9.1/gems/activesupport-3.2.8/lib/active_support/dependencies.rb:251:in `require'
etc. etc.
Based on the above information, I ran rake under strace and discovered that it was looking for thin_parser.so in the wrong place. I was able to fix the problem by installing this symbolic link (I did this as root since I installed thin as root). Obviously, adjust the path to where your version of thin is installed:
cd /usr/local/share/gems1.9/gems/thin-1.6.3/lib
ln -s ../ext/thin_parser/thin_parser.so .
Poof! That fixed it for me.
