How to change the version of bundler being used in rails?

Question

When I run the following command, it gives me the available installed versions of bundler:

command :

gem list | grep "bundle"

output:

bundler (1.11.2, 1.10.6, 1.10.4, 1.3.6, 1.3.0, 1.3.0.pre)

The current version of bundler I obtained was 1.11.2 using the following command:

bundler --version

I want to use version 1.3.6 How do I swap the current version of bundler with the available ones?

Answer 1

Normally during development Bundler is used from it's executable on your system, so I don't believe you can specify a specific version in your Gemfile, for example. (You might try it, though). However, you can install the version you like and force the shell/rubygems to use that version:

$ gem install bundler -v 1.3.6
...
1 gem installed

$ bundle _1.3.6_ -v
Bundler version 1.3.6

To get my machine to use 1.3.6 by default I had to uninstall 1.11.2.

Update: I tried specifying gem 'bundler', '~> 1.3' in one of my projects and it worked, although the CLI for bundler still used the system default version.
