Heroku预编译的资产失败 [英] Heroku Precompiled Assets Failed

问题描述

在解决以下问题时遇到困难，并弄清楚为什么我的资产无法在slug编译时进行预编译......奇怪的是，当我检查实时日志时资产在运行时正常编译......任何想法？是否试图连接到数据库？

 为Rails资产管道准备应用程序
运行：rake资产：预编译
 rake中止！

解决方案我刚刚添加了Unicorn，我在config中添加了以下内容到我的application.rb中，并且能够预编译：

  config.assets.initialize_on_precompile = false 
  

I am having difficulties troubleshooting the following and figuring out why my assets are failing to precompile at slug compilation... the odd thing is, is that the assets compile fine at runtime when I check the live logs... any ideas? Is it trying to connect to the database?

解决方案

I had just added Unicorn, I added the following to my application.rb in config and was able to precompile:

config.assets.initialize_on_precompile = false
