`buildpacks`不是Heroku的命令

Question

我想一個buildpack添加到我的Heroku應用程序，但運行

heroku buildpacks:set third_party_buildpack 

回報

! `buildpacks:set` is not a heroku command. 
! See `heroku help` for a list of available commands. 

，當我運行

heroku buildpacks 

我得到

! `buildpacks` is not a heroku command. 
! See `heroku help` for a list of available commands. 

即使

heroku help buildpacks 

返回同樣的事情，

heroku help

注意缺少幫助主題buildpacks的。我的英雄版本顯示

heroku-toolbelt/3.25.0 (x86_64-linux) ruby/2.2.4 

Heroku的buildpack頁面聽起來像heroku buildpack：set命令應該是開箱即用的。有誰知道爲什麼這個功能似乎不存在於我的機器上？我的應用程序在Ruby（2.2.4）在rails（4.0.3）上運行Ubuntu 14.04。提前致謝。

我昨天有這個問題。事實證明，我有一個漂亮的Heroku CLI版本或安裝了heroku gem。

當您在終端輸入heroku --version時，您會看到什麼？

見下從這裏：https://devcenter.heroku.com/articles/heroku-cli

$ heroku --version 
heroku-toolbelt/3.43.9 (x86_64-darwin10.8.0) ruby/1.9.3 
heroku-cli/5.2.39-010a227 (darwin-amd64) go1.6.2 

你應該看到的Heroku，工具區/ X.Y.Z輸出。如果你不這樣做，但是已經安裝了Heroku CLI，那麼你的系統中可能會有一箇舊的heroku gem - 卸載它。

我跑gem uninstall 'heroku'從這裏跑了安裝程序：https://devcenter.heroku.com/articles/heroku-cli 然後gem install 'heroku'然後buildpack Heroku的命令，開始爲我工作。
