从heroku宝石切换到heroku-api topolbelt

Question

Heroku非常善于使事情变得简单...但是这个...并不是很多。你如何从heroku宝石切换到新的工具腰带？下面是我所采取的步骤：

$ heroku version: heroku-gem/2.32.5 (x86_64-darwin11.4.1) ruby/1.9.3 autoupdate 
removed 'gem "heroku"' from gem file 
added 'gem "heroku-api"' to gemfile 
deleted gemfile.lock 
$ bundle install 
installed toolbelt via the package installer 
$ heroku login ... returns "Authentication successful" 
$ heroku version: STILL RETURNS heroku-gem/2.32.5 (x86_64-darwin11.4.1) ruby/1.9.3 autoupdate 

两个问题：

#1 Why is my version still using the heroku-gem after taking the steps above? 
#2 Where do I put "heroku = Heroku::API.new(:api_key => API_KEY)" for use with the heroku-api gem? 

Answer 1

删除Gemfile.lock的文件并没有削减它。我不得不运行宝石卸载heroku（我有9版本）...之后，英雄版本显示工具带。
