Uninstall Rails completely

Question

I’m trying to uninstall Rails completely, but I can’t get the grip of it.

Here’s what I tried:

$ gem update
rails 4.0.0.beta1 instal         


        

Answer 1

you just try this command.it will help to uninstall all rails "gem uninstall railties" I think this is the only method to fully uninstall all rails

Answer 2

sudo gem uninstall rails -v 4.0.0.beta1

It should help.

Answer 3

First you should understand what is the location of rails. Type in your console (bash, zsh, etc.)

which rails

If it's located in your home folder, like:

/home/your_name/.rvm/gems/ruby-1.9.3-p392/bin/rails

Then, you should remove it using local gem:

gem uninstall rails

Otherwise, you probably have to use sudo:

sudo gem uninstall rails

NOTE: you can check your rails versions as following:

Local:

gem list rails 

Global:

sudo gem list rails
