我需要帮助来解决我的应用程序的资产管道问题。任何人都可以看看我缺少的东西吗？提前致谢。
我正在使用以下rails 3.2.13，ruby 1.9.3（用于开发）和ruby 2.0.0（用于heroku上的生产）。 （我在生产中使用不同版本的ruby作为一个名为bybosa的宝石无法与ruby的开发版本一起安装......我不确定这是否是问题的根源。可能不是......）。
我预先编译了本地运行的资产：bundle exec rake assets：precompile RAILS_ENV = production。资产得到很好的预编译并放在public / assets /目录中。但是，此过程运行时出现错误：＆＃34;无法转储匿名类＆＃34;错误。这似乎与sass和sprockets有关......但编译完成后放在public / assets目录中的文件。原始图像，以及具有长哈希扩展的相同图像名称。我承诺一切git并从git部署到heroku。 Heroku不运行资产编译，因为public / assets目录中有一个清单文件。
应用程序部署得很好，但图像无法正常提供。提供CSS和JS。布局的样式至少是预期的。所以CSS和JS没问题（我可以注意到）。 仅提供两张图片。其他10张图片均未送达。 Heroku日志显示找不到这些图像的错误404。这些图像的路径是/ assets / image_name。提供的两个映像具有这些路径/ assets / image_name + hash（在预编译操作期间由资产管道生成的字母和数字的组合）。检查网页上的元素时，只有那两个显示的图像在图像名称后面有长哈希。所有其他图片都没有哈希... 我想知道为什么网络服务器无法找到其他图像。为什么Web服务器没有通过具有长哈希扩展的资产管道将图像指向为预编译？
在开发环境中，所有图像都能很好地显示出来。这里，图像由其简单名称引用（没有资产管道扩展）。
