從heroku寶石切換到heroku-api topolbelt

Question

Heroku非常善於使事情變得簡單...但是這個...並不是很多。你如何從heroku寶石切換到新的工具腰帶？下面是我所採取的步驟：

$ 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 

兩個問題：

#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

刪除Gemfile.lock的文件並沒有削減它。我不得不運行寶石卸載heroku（我有9版本）...之後，英雄版本顯示工具帶。
