Answer 1

This issue comes up when your Gemfile.lock has different versions of the gems installed on your machine. A warning comes up as :

You have already activated rake 11.1.2, but your Gemfile requires rake 11.1.1. Prependingbundle execto your command may solve this.

Adding bundle exec forces bundler to run the command ignoring difference of version.

Fortunately, there is a gem that solves this: rubygems-bundler.

> gem install rubygems-bundler

> gem regenerate_binstubs

After this try your rake commands it will work fine.

Answer 2

Remove particular version of rake

with command of gem uninstall rake

and it will allow you to run rake command

Answer 3

Try this:

bundle exec rake your_task_name
