Redmine : error in running redmine_wktime plugin : rufus-scheduler-3.0.3

Question

I'm using redmine 3.3.1

and i wanna install the plugin "redmine_wktime"

DOCUMENTATION of the plugin : https://github.com/dhanasingh/redmine_wktime,

As the documentation says i need to :

1) import the plugin files to the plugins folder of my redmine folder : /opt/redmine/redmine-3.3.1/plugins/ (DONE)

2) update the rails schema by running this :

rake redmine:plugins:migrate NAME=redmine_wktime RAILS_ENV=production (DONE)

3) giving the read acces to the folder :

/opt/redmine/redmine-3.3.1/public/plugin_assets/redmine_wktime/ (DONE)

4) bundle install (DONE)

5) restarting apache : service apache2 restart (DONE)

until this step everything was done without any problemes or errors messages :

but when i'm trying to running the redmine application at localhost i'm getting this error , and it says that something goes wrong with "rufus-scheduler-3.0.3"

Could not find rufus-scheduler-3.0.3 in any of the sources (Bundler::GemNotFound)

This problem was resolved by running simply:

bundle install --deployment

instead of just:

bundle install
