I'm having problem with the rails console. It gives me this error when I try installing the readline module using:
yum install readline-devel
I'm working with Rails 3.1.1 on a fedora 14 machine.

ADDITION:
i tried installing readline via rvm following this link
[readline install via rvm][1]
and rails c worked but the problem is when reboot my system and tried again it appears to show this error

You need to install readline headers and libraries prior installing the Ruby interpreter (it is shown once you complete the installation of RVM)
You can see that again doing rvm notes
Check that the readline gem is installed. The above yum command installs the readline library, but to interact with it, you need the gem.
If it's not in your Gemfile, add it, run bundle install and check again.

As I understand it has something to do with a version of Ruby but I have no idea how to resolve the issue.
It looks like you may need to do a gem install bundler and get the bundler gem to get rails up and running.
STEP (1): install the bundler gem:
sudo gem install bundler
Once completed, you should get a message similar to this:
Fetching: bundler-1.16.1.gem (100%)
Successfully installed bundler-1.16.1
Parsing documentation for bundler-1.16.1
Installing ri documentation for bundler-1.16.1
Done installing documentation for bundler after 6 seconds
1 gem installed
STEP (2): try checking the bundler version:
bundle -v
You should get a version number like this:
Bundler version 1.16.1
STEP (3): now you can use bundle install:
bundle install
I hope my answer helps.

my ruby version is 2.3.3 and rails 5.0.3
Thank you
`check_version_conflict': can't activate json-1.8.2, already activated
json-1.8.3 (Gem::LoadError)
This is due to bundler trying to install json-1.8.2 when there is json-1.8.3 already installed. This is because bundler will use Gemfile.lock to install specified gem versions of gems.
You should do gem cleanup and followed by gem update json. This will update the json to latest version in Gemfile.lock and will resolve the problem.
I had recently followed multiple blogs to completely wipe out rvm, rails and then reinstalled ruby 2.3.0 and rails 5. Made and app using it no issues. But the moment I opened a new terminal window in my machine it was not recognising rails at all as if it was only installed in that particular terminal.
So I just completed my work in that single terminal. Now when I restarted my laptop, I am unable to run the same app. I do not wish to reinstall everything again as I am sure this is a small configuration problem. Why is this happening?
The error message that I am getting now:
/Users/sahil/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/dependency.rb:319:in `to_specs': Could not find 'railties' (>= 0.a) among 30 total gem(s) (Gem::LoadError)

I have already seen other similar questions where they ask to reinstall everything again which I do not want to do as it worked after installing but did not work on system restart.
Now I did gem install rails in one terminal and the app is working again, but if I try to open a new terminal and give the same command rails s, it gives me this error,

You mentioned that you reinstalled ruby 2.3.0 and Rails 5. However it seems rbenv is trying to load your project with ruby 2.3.1.
You should switch to ruby 2.3.0. I guess you should be able to do: rbenv local 2.3.0.
To avoid this from happening again though, you should add a .ruby-version dotfile to your project root and in the file only add 2.3.0.
Hope that works

I am completely at a loss. Help is appreciated/
You need to install ruby gem as well:
gem install sqlite3
If your program has a Gemfile, do:
gem install bundler
bundle install
Another advise, install ruby via RVM, it will save you from a number of headaches.
UPDATE:
Most likely you will also need the following package:
sudo apt-get install libsqlite3-ruby
You can also install the gem as follows using apt:
apt-get install ruby-sqlite3
or in my case:
apt-get install sqlite3-ruby
I would avoid installing Ruby using apt-get because you'll face a lot of problems (versions, gem management, etc) down the road. Use RVM instead.
Remove your apt-get installations (especially if your ruby -v returns something before 1.9) and then follow the instructions at http://rvm.io/rvm/install
RVM will allow you to install multiple Ruby versions and manage your gems more easily.
Once you're done with the rvm installation, do the following:
gem install sqlite3 -v 1.3.6
Once you have RVM running, things should become easier... Don't worry about the extra time you're spending in the beginning, it'll pay off :-)

It's very annoying because, I did:
Successfully installed rack-1.1.0
1 gem installed
Installing ri documentation for rack-1.1.0...
Installing RDoc documentation for rack-1.1.0...
But it always says that error. I have Rails 2.3.5 but I don't think the error is Rails related, but more like my server-related lol.
Thanks for help!
You installed Rack 1.1.0, the version required is 1.0.x.
$ gem uninstall rack
$ gem install rack -v 1.0.1
the above works, when installing, you have to indicate the version: "-v 1.0.1"
for some reason, it wont work otherwise.
