Very new to Rails, so bear with me -
Currently paranoid that my ruby and gem versions aren't up to date because I'd occasionally get error messages when running rails test. Previously had rvm and rbenv both installed, but wow I've removed both and reinstalled rvm only.
When I go into a irb and call an action that doesn't work, such as: "foo".select, I get a simple error message:
NoMethodError: private method 'select' called for "foo":String
from (irb):4
from /Users/Joseph/.rvm/rubies/ruby-2.3.1/bin/irb:11:in '<main>'
However, when I type the same command "foo".select in rails console instead, I get:
NoMethodError: private method `select' called for "foo":String
from (irb):1

Is this normal? Or is there something wrong with my gems here?
There's nothing wrong with your gems. The thing is that when you run irb, it's just that. You only run the ruby interactive.
When you run rails console in order to show you the console it needs to go and set it for you with ActiveRecord, rails core, etc. So this (below) is all it does before it's set.

Notice that irb is executed really fast, while rails console takes its time, depending on your initializers, configurations, etc.

You are trying to start rails server in interactive Ruby Shell (IRB or irb), or may be rails console.
use the command
rails s
in your terminal
You should have to look into this http://guides.rubyonrails.org/getting_started.html for the rails basics.
You are using rails console. Get out of the console by typing quit and then type rails s

I am using gemset with Ruby version 2.2.3 and Rails version 4.2.5.
Please suggest some solution.Thanks in advance
After restarting the system it got worked !!!
Rails error messages in terminal are too long and contain often useless information. Is there a gem/solution to shorten rails error messages?

What I want: (optionally in red)
NoMethodError: undefined method `red' for 1:Fixnum
===>Long error message saved in e. Get full messages with 'puts e'
Would this be possible?
You could try better_errors gem.
It provides also a better explanation of the errors via browser.
This is the link to the github repo
EDIT
If you are looking also to a customizable console (also the exception trace) try to see pry
I am using the ancestry gem and i m testing my model in the console first.When i use
root = Message.create(:content => "hello")
It inserts data into the database but when i use
child = root.children.create(:content => "hhjjh")
It gives an error.This is the log
NoMethodError: undefined method `scoped' for #<Class:0x007fa4a61182b0>

I don't know what i m doing wrong but i think this is suppose to work.Any ideas?
It looks like your version of Ancestry is 1.2.3 or something. Updating to a new version looks like it should fix that problem.

In rails console when I commit an error, the console displays tons of lines which I don't want to see. Can this be silenced?
I've found that you can add this line:
Rails.backtrace_cleaner.add_silencer { |line| line =~ /rvm/ }
in config/initializers/backtrace_silencers.rb but this doesn't resolve the problem.
