💡 Hint

Common Mistakes

Using 'ruby' alone runs the script but ignores Bundler gem isolation.

Using 'gem install' is for installing gems, not running scripts.

Using 'rake' is for running tasks, not general Ruby scripts.

Using bundle exec runs the Ruby script with gems isolated to the bundle environment.

💡 Hint

Common Mistakes

Running 'ruby' alone ignores Bundler isolation.

Using 'gem install' is for installing gems, not running scripts.

Using 'rake' is unrelated to running arbitrary Ruby scripts.

After installing gems, bundle exec runs the script using the installed gems isolated by Bundler.

3fill in blank

hard

Fix the error by completing the command to run a Rake task with Bundler isolation.

Ruby

[1] rake db:migrate

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Running 'rake' alone may use system gems, causing version conflicts.

Using 'ruby' alone does not run rake tasks.

Using 'gem install' is for installing gems, not running tasks.

Using bundle exec before rake ensures the task runs with the correct gem versions.

4fill in blank

hard

Fill both blanks to create a command that installs gems and runs a Ruby script isolated by Bundler.

Ruby

[1] install && [2] ruby script.rb

Drag options to blanks, or click blank then click option'

Abundle

Bbundle exec

Cgem

💡 Hint

Common Mistakes

Using 'gem install' instead of 'bundle install' for gem installation.

Not using 'bundle exec' to run the script causes gem version conflicts.

The first blank is bundle to install gems, and the second is bundle exec to run the script with gem isolation.

5fill in blank

hard

Fill all three blanks to create a command that installs gems, runs a Rake task, and then runs a Ruby script all isolated by Bundler.

Ruby

[1] install && [2] rake db:seed && [3] ruby app.rb

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Running rake or ruby commands without 'bundle exec' causes gem conflicts.

Using 'rake' or 'ruby' alone without 'bundle exec' ignores the Gemfile.lock.

Use bundle to install gems, then bundle exec to run both the rake task and the Ruby script with gem isolation.
