bundle install gives undefined method `ruby' for #<Bundler::Dsl:0x00000001c4e1f8>

Question

bundle install is giving:

> undefined method `ruby' for #<Bundler::Dsl:0x00000001c4e1f8>

Any idea how to fix? I'm using Ruby 1.9.3-p125.

Answer 1

Version 1.2 of Gembundler introduced a ruby method to the dsl that allows you to specify the Ruby version your app should use.

It looks like the Gemfile you’re using was written for this new version, but the version of bundler you have doesn’t support the ruby method. You need to either install the latest bundler (gem install bundler should do it) or remove the line from your Gemfile.

Answer 2

Run these commands the problem will fix

step 1: install bundler gem install bundler
step 2: bundle install

it will fix the issue..
