Question

我刚安装了carrierwave，并设置了我的rails 4应用程序，以便通过雾在亚马逊s3上存储图像。该应用程序正在使用Carrierwave工作并部署到Heroku（但图像正在用dyno清除）。在一些初始问题之后，我让它在我的本地主机上运行（据我所知）。

现在我无法将新版本推送到Heroku。我重置了DATABASE。预编译资产，现在尝试迁移数据库。以下是我得到的错误。

我试图在Uploader文件中包含并不包含Sprockets，并以任何方式获得相同的错误。我知道链接器不再包含在Rails 4的主服务器中。我现在已经安装了sprockets-rails和sprockets-helper gem。我也试图在文件的顶部要求它们（我完全不理解这一点，但遵循这个建议https://github.com/petebrowne/sprockets-helpers）。没有任何效果。关于如何解决这个问题的任何建议。如何初始化Sprockets :: Helpers。感谢。

我犯了一个非常愚蠢的错误。我已经更正了我的应用程序中的文件，并将更改提交给主服务器，但我继续运行heroku运行rake db：migrate命令并得到相同的错误，所以我认为我还没有解决它。我忘了把新版推到heroku！因此仍然得到相同错误的原因。

此外，如果其他人有类似的问题。确保你已经解决了这个问题：

错误：推送到Heroku时未初始化的常量Sprockets :: Helpers
