could not find compatible versions for gem "rubyzip"-Twitter bootstrap

I am using

gem ‘axlsx_rails’

gem ‘acts_as_xlsx’

for downloading file into excel.
Now I am trying to add the following gem

gem ‘caracal’

for downloading file into docx.
Whenever, I am trying to run

bundle install, I got the following error

Bundler could not find compatible versions for gem “rubyzip”: In
snapshot (Gemfile.lock):
rubyzip (= 1.0.0)

In Gemfile:
acts_as_xlsx was resolved to 1.0.6, which depends on
axlsx (>= 1.0.13) was resolved to 2.0.1, which depends on
rubyzip (~> 1.0.0)

caracal was resolved to 0.1.0, which depends on
  rubyzip (~> 1.1)

Running bundle update will rebuild your snapshot from scratch, using
only the gems in your Gemfile, which may resolve the conflict.

My gem file looks like following

source ‘https://rubygems.org‘

gem ‘rails’, ‘4.1.9’

gem ‘mysql2’, ‘~> 0.3.19’

gem ‘sass-rails’, ‘~> 4.0.3’
