GemNotFound rake when using whenever in development - ruby-on-rails

Question

I'm getting this one error I don't understand (I'm fairly new to rails) when using the gem 'whenever' in development mode.
What I did was update config/schedule.rb and run
whenever --update-crontab --set environment='development'
crontab -l lists:
* * * * * /bin/bash -l -c 'cd /home/vic/Desktop/WorkflowProject && bundle exec bin/rails runner -e development '\''Task.new2'\'' >> log/whenever.log 2>&1'
at config/schedule.rb
set :output, 'log/whenever.log'
every 1.minute do
runner "Task.new2"
end
at log/whenever.log
bundler: failed to load command: bin/rails (bin/rails)
Bundler::GemNotFound: Your bundle is locked to rake (11.3.0), but that version could not be found in any of the sources listed in your Gemfile. If you haven't changed sources, that means the author of rake (11.3.0) has removed it. You'll need to update your bundle to a different version of rake (11.3.0) that hasn't been removed in order to install.

Answer 1

Try the below commands.
gem install rubygems-bundler
gem regenerate_binstubs

Answer 2

Are you sure to have bundler installed? Try running bundle install inside your application directory.
If no, see Jayaprakash's answer above.
If yes, try bundle exec whenever --update-crontab --set environment='development'.
Update:
Ahh, missed that you are seeing error when your task executes.
Try this in your config/schedule.rb
env :PATH, ENV['PATH']
set :output, "#{ Whenever.path }/log/whenever.log"
every 1.minute do
runner "Task.new2"
end
