从heroku gem切换到heroku-api topolbelt

Question

Heroku非常擅长制作simple...but this...not的东西。如何从heroku gem切换到新的工具带？以下是我采取的步骤：

 $ 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文件并不能将其删除。我不得不运行gem卸载heroku (我有9个版本)...之后，heroku版本向工具带展示。
