我正在使用Rails 3.2.6和Ruby 1.9.3。我创建了应用程序，并使用 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？
如何部署到Heroku？
答案 0 :(得分：2)
通过查看错误，我可以说您没有在本地运行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。
您可以从此链接Rails Asset Pipeline on Heroku Cedar了解Heroku。
我希望这会对你有所帮助。
