Topic: bundle install --no-deployment

I have no idea how this came to be but i uses to be able to just run bundle on my local box to install new gems bit now i have been getting a message that i have to run bundle install --no-deployment

does any one know how to revert back to how it was

full message

You are trying to install in deployment mode after changing
your Gemfile. Run `bundle install` elsewhere and add the
updated Gemfile.lock to version control.

If this is a development machine, remove the Gemfile freeze 
by running `bundle install --no-deployment`.
