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 tried running bundle over rbenv but I got this error:

Then I tried these commands:
$ gem -v
2.5.0
$ rails -v
Rails 4.2.4
$ bundle -v
Bundler version 1.10.6
$ rbenv -v
rbenv 0.4.0-205-g5fb9c84
Why can't I run bundler?
Run the below command in your terminal
gem install rb-readline
Hope it helps!
I changed the source from https://rubygems.org to http://rubygems.org and ran:
gem update --system
bundle install
now it's working.
I'm trying to install ruby on rails on debian... I installed everything.
I installed execjs, therubyracer and node.js, too.

I made a reboot after the installation of execjs, therubyracer and node.js...
For platforms for which there is binary version of therubyracer gem available, there are no dependencies other than ruby and rubygems. If there is not a binary version for your system, then you will need to compile it from source. To do this, you must have v8 > 3.11.8 installed somewhere on your system.
Try adding following to your Gemfile
gem 'therubyracer', '0.11.0beta5'
gem 'libv8', '~> 3.11.8'
Now, cd to your project and bundle install
$ cd <project>
$ bundle install

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.
I got an error when trying to run $rails console

Hmm... so i tried to uninstall the mysql2 gem, and reinstall the version 0.2.7 gem
sudo gem uninstall mysql2 -i /Library/Ruby/Gems/1.8
And I changed the gemfile:
gem 'mysql2','0.2.7'
Ran Bundler in my app directory:
bundle install
But it installed the version 0.3.2 back again!!! Can anyone help, I honestly don't know what happened here.
sudo gem uninstall mysql2
in Gemfile gem 'mysql2', '< 0.3'
bundle update
with your
gem 'mysql2','0.2.7'
Try
bundle update
it builds the bundle from scratch
