Is it necessary to update the line of gem in Gemfile when using bundle update gem-name?

I want to update my jquery_rails gem, actual version is 3.0.4, the following command will update it

bundle update jquery_rails

so, what about my Gemfile, it is necessary to update version of jquery_rails too ? ("i work currently in local")

in my Gemfile i have version 2.2.1

gem 'jquery-rails', '2.2.1'

Update

i change gem 'jquery-rails', '2.2.1' in my Gemfile to gem 'jquery-rails', '3.0.4', and i tried to execute bundle update jquery-railsbut an error is occur :

 Bundler could not find compatible versions for gem "railties":
In Gemfile:
rails (= 4.0.0) ruby depends on
  railties (= 4.0.0) ruby

sass-rails (= 4.0.0) ruby depends on
  railties (4.0.1)

To answer your question directly, in this case yes it is necessary to update the version in Gemfile, but it is not always.

Running bundle update <gem> will cause Bundler to find the most recent version of the gem and its dependencies that satisfies all of the requirements of the Gemfile. Since you have specified a requirement of a specific version, Bundler will only allow that version. You can also specify a more flexible version in your Gemfile: gem 'jquery-rails', '~> 2.2.0' would allow it to use any 2.2.x version, or '~> 2.2' would allow any 2.x.

The issue with sass-rails is separate. You can solve it by updating to sass-rails 4.0.1. See can't get gemfile to allow for bundle update

Firstly, you should update your gem file and specify required version of the gem, then run bundle update jquery_rails.

Error tells you, that you have gems which required different version of railties. Try to change versions of rails to 4.0.1, sass-rails to 4.0.1 and railties to 4.0.1 and update these gems via bundle.
