当我运行git push heroku master命令时，Heroku推送失败
我使用的是Rails 3.2.6和Ruby 1.9.3 。 我已创建应用程序，我已使用git push在GitHub存储库中推送该应用程序。
当我使用git push heroku master命令在Heroku部署应用程序时，出现以下错误：

我无法得到它，发生了什么？
我怎样才能部署到Heroku？
通过查看错误，我可以说你没有运行assets:precompile在本地assets:precompile任务。
现在，在使用git push heroku master命令之前，您只需按照以下步骤操作：
RAILS_ENV=production bundle exec rake assets:precompile git add public/assets git commit -m "vendor compiled assets"
完成上述步骤后，使用git push heroku master命令，这将有助于将应用程序部署到Heroku。
你可以通过Heroku Cedar上的链接Rails Asset Pipeline了解Heroku 。
我希望这能帮到您。
