Heroku, Zentest, Rails 3 - error while pushing

Question

I am trying to push to heroku by git push heroku master. And I have this error.

 Fetching source index for http://rubygems.org/
       Installing rake (0.9.2.2) 
       Installing ZenTest (4.6.2) /usr/ruby1.9.2/lib/ruby/1.9.1/rubygems/installer.rb:170:in `install': ZenTest requires RubyGems version ~> 1.8. Try 'gem update --system' to update RubyGems itself. (Gem::InstallError)

But I do not need ZenTest at all. I deleted this gem from my gemfile.

Now my gemfile looks like this

source 'http://rubygems.org'

gem 'rails', '3.1.1'
gem 'sqlite3'
gem 'jquery-rails'
gem "rmagick"
gem "carrierwave"


#gem 'compass_twitter_bootstrap'
#gem 'gravatar_image_tag', '1.0.0.pre2'

group :development do
  #gem 'rspec-rails', '2.6.1'
  #gem 'annotate', '2.4.0' 
end

group :test do
  #gem 'rspec-rails', '2.6.1'
  #gem 'webrat', '0.7.1'
   gem 'turn', :require => false 

end

group :assets do
  gem 'sass-rails',   '~> 3.1.4'
  gem 'coffee-rails', '~> 3.1.1'
  gem 'uglifier', '>= 1.0.3'
  gem 'twitter-bootstrap-rails'

end

source :gemcutter
    gem 'sinatra', '1.0'

Then i run rvmsudo bundle to delete it from gemfile.lock.

But i still have this error. What can do with this?

Answer 1

Did you do a git commit after modifying the gemfile?

Answer 2

OP didn't need that ZenTest test gem, but for those getting here because of heroku failing to use ZenTest 4.7.0 (which could be required by some dependency gem such asRubyInline), use gem 'ZenTest', '~> 4.3.0' in your GemFile (hopefully this version is sufficient).

Later version maybe supported as well, didn't test.
