Question

我正在尝试将buildpack添加到我的heroku应用程序中，但正在运行

heroku buildpacks:set third_party_buildpack

返回

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

当我跑

时

heroku buildpacks

我得到了

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

即使

heroku help buildpacks

返回相同的内容，

heroku help

返回

请注意帮助主题中缺少buildpack。我的heroku版本显示

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

Heroku的buildpacks页面使它听起来像heroku buildpacks：set命令应该开箱即用。有谁知道为什么我的机器上似乎没有这个功能？我的应用程序是ruby（2.2.4）on rails（4.0.3），我运行的是Ubuntu 14.04。提前谢谢。

昨天我遇到了这个问题。事实证明我安装了一个相当旧版本的Heroku CLI或heroku gem。

当您在终端中输入heroku --version时，您会看到什么？

请参阅下面的内容：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

您应该在输出中看到heroku-toolbelt / x.y.z.如果你没有，但已经安装了Heroku CLI，你的系统上可能有一个旧的heroku gem - 卸载gem。

我运行gem uninstall 'heroku'并从此处运行安装程序：https://devcenter.heroku.com/articles/heroku-cli 然后gem install 'heroku'然后buildpack heroku命令开始为我工作。

`buildpacks`不是heroku命令
