In

Answer 1

Have you tried to gem install bundler? I'd be surprised it doesn't install when you install the rails gem, but it seems that's your issue...

Answer 2

I got the same error as you while upgrading a non-rails project from Ruby 1.8.x to Ruby 1.9.x. The problem is that the current dir has been removed from LOAD_PATH.

Why does Ruby 1.9.2 remove “.” from LOAD_PATH, and what's the alternative?

I had to change a few places from require to require_relative and then it worked.

Answer 3

In your Gemfile, under group :test do add gem 'rack'.

Answer 4

I just had the same issue. I didn't solve it fully but by running:

bundle exec rake <task> 

I was able to finally run the task I wanted without the error you have.

Answer 5

Got the same missing bundler message running rake after upgrading to Ruby 1.9.2.

Rake needed updating and bundler needed to be reinstalled:

sudo gem update rake

sudo gem install bundler

Reinstalling bundler might have fixed the error, but you want to make sure rake is right too.

Answer 6

try

gem install bundler

bundle install

to install the gems needed.

rake tasks will fail if you do not have the gems necessary for the rails app.
