updated rbenv rails not found

I have updated all the brew formulas with brew update && brew upgrade. I after I upgrading I noticed that rails is not found but when I type 

which rails

it returns /usr/bin/rails. All I can guess is I have to add rails path to .zshrc again. But, I am not sure what all I need to add to .zshrc file.

What are all the things that update broke.

.zshrc file

# store everything under Homebrew's prefix, include this in your profile:

I solved in this manner:

1) sudo apt-get update

2) sudo apt-get install -y ruby-build

3) git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build

4) rbenv install 2.3.0

5) rbenv global 2.3.0

The only solution I came across is to re-install ruby & rails. I think while upgrading rbenv existing install somehow got removed

# Install Ruby
rbenv install 2.2.3
rbenv global 2.2.3
ruby -v

gem install rails -v 4.2.4

rbenv rehash

rails -v
# Rails 4.2.4

Most likely you have Rails squirreled away in some particular gemset in some rvm-managed Ruby version, but you haven't told rvm to use it again yet.

Look at your installed Ruby versions (with rvm list). Chances are that the one you were using before is still there. If you recognize one, use it (with rvm use ruby-2.2.4 or whatever version), else start looking in all the versions.

For each Ruby version you inspect, look at the gemsets rvm is managing under it (with rvm gemset list). Chances are, you either created one for some Rails project, or as a starter for Rails projects in general (that's what I do), or maybe you just left all the gems to be installed into the default or global gemsets.

If you recognize a particular one, use it (with rvm gemset use rails_4_2 or whatever gemset name), else start looking in all the gemsets. You'll eventually find the right combination.

If you don't, then go through the same process as from scratch. First make sure you're using the Ruby version you want (you may need to install it, with rvm install 2.3 or whatever version). Then create a new gemset (with rvm gemset use --create rails_4_2 or whatever you want to call it). Lastly, gem install rails.
