Rails 4 railties's executable "rails" conflicts with rails

Question

I have rails 4 and that's my default version (and I still wants it to be). but I d'like to add rails 3.2 on my computer. On the following command: gem install rails -v 3.2.16

I have this Warning:

railties's executable "rails" conflicts with rails
Overwrite the executable? [yN]

I d'like to know if this will cause some bugs to my 4.0.1?

You should use `rvm` and install rails 3 into a new `gemset` — Малъ Скрылевъ, Jan 03 '14 at 08:50

You should use rvm and install rails 3 into a new gemset. Exactly do steps as follows:

Install rvm.
Install or use a ruby:
```
rvm install ruby-2.0.0
```

Create a gemset, and then use it:

rvm gemset create rails_1_app
rvm gemset use rails_1_app

Install bunlder:
```
gem install bundler
```
Create Gemfile, and specify rails 4 in it:
```
gem 'rails', '~> 4.0'
```
Install requires gems:
```
bundle install
```
Repeat steps 3-6 for a new gemset, but specifying rails 3 in it:
```
gem 'rails', '~> 3.0'
```

Thks majioa I need to ask for a presicion I have already ruby 2.0.0 and rails 4 installed. Do I have to start at the #3 to 7 only once? or should I do 1-6+3-7? – Papouche Guinslyzinho Jan 03 '14 at 09:11
you can omit first 3-6 point, but gem set you will have the `default` one. – Малъ Скрылевъ Jan 03 '14 at 09:13
thks majoia for the precision! – Papouche Guinslyzinho Jan 03 '14 at 09:16
