更改rails环境。到生产

Question

我的rails应用程序在开发模式下工作得很好，但是如果我将它更改为生产模式，它会给出错误的错误，并且我看不到背后的任何原因。你知道有什么可能的问题吗？

这是我的错误消息：

谢谢所有关心的人。

当我输入rake assets:预编译时，我得到：

rake aborted!
no such file to load -- uglifier
  (in /home/erogol/Dropbox/Bunch_It/app/assets/javascripts/application.js)

Tasks: TOP => assets:precompile:primary
(See full trace by running task with --trace)
rake aborted!
Command failed with status (1): [/home/erogol/.rvm/rubies/ruby-1.8.7-p358/b...]

Answer 1

问题出在config.assets.compress = true上。它对我的javascript文件产生了问题。我将其设置为false，然后我的应用程序开始正常工作。但是，我不知道设置为false是否会导致我的程序丢失。

Answer 2

尝试在\config\environments\production.rb文件中设置config.serve_static_assets = true。这对我有帮助。

Answer 3

从错误消息中可以看出，Rails无法找到文件: /favicon.ico。请确保它存在。
