很简单，这就是我得到的；

 sa@sa-VPCW11S1E:/opt/hubot/bin$ heroku buildpacks

 sa@sa-VPCW11S1E:/opt/hubot/bin$ sudo git push heroku master

虽然我确实在应用程序 git push 上设置了一个 buildpack 因为没有检测到 buildpack 而失败？

我该如何解决这个问题，这实际上是部署 hubot 的正确步骤吗？

heroku 构建包仍然使用检测脚本来识别正在使用的语言。由于 Hubot 不是 java 项目，而且看起来您正在使用 java build pack，我怀疑检测脚本失败。

要解决此问题，请尝试删除 buildpack。

% heroku buildpacks:remove heroku/java

在此之后，我会尝试，

% git push heroku master

（可选）我相信rediscloud某些脚本需要插件。你可以添加它，

% heroku addons:create rediscloud

然后查看日志heroku logs，看看会发生什么。

hubot/deploying/heroku.md中有一个很好的部署指南
