预编译麻烦。 尝试使用heroku部署Rails应用

[英]trouble with precompilation. trying to deploy a rails app with heroku

 原文  2013-06-22 01:44:40  5   2    ruby-on-rails/ deployment/ pre-compilation

问题描述

看到这个https://help.heroku.com/tickets/89264

基本上，我更新了config/environments/production.rb文件，并按照
这个建议https://devcenter.heroku.com/articles/rails-asset-pipeline#compiling-assets-locally ，但是它仍然不起作用。

我只是改变了
# Precompile additional assets (application.js, application.css, and all non-JS/CSS are already added) # config.assets.precompile += %w( search.js )
至
# Precompile additional assets (application.js, application.css, and all non-JS/CSS are already added) config.assets.precompile += %w( home.css )

然后执行以下操作： 

~/collegeanswerz >>  RAILS_ENV=production bundle exec rake assets:precompile
/Users/adamzerner/.rvm/rubies/ruby-1.9.3-p327/bin/ruby /Users/adamzerner/.rvm/gems/ruby-1.9.3- p327@rails3tutorial2ndEd/bin/rake assets:precompile:all RAILS_ENV=production RAILS_GROUPS=assets

但我仍然遇到同样的500错误。

谁能帮我这个？ 我渴望部署，但无法弄清楚自己在做什么错。 我通过https://devcenter.heroku.com/articles/rails-asset-pipeline#compiling-assets-locally和http://guides.rubyonrails.org/asset_pipeline.html阅读，但我仍然不知道出了什么问题。 任何帮助，将不胜感激。 谢谢。

编辑：我只添加了home.css到config/environments/production.rb 。 我虽然有其他CSS文件和JavaScript文件。 我需要将它们与home.css一起添加吗？ 我对需要添加到此文件中的内容和不需要添加的内容感到困惑。

现在，我看到了您的日志，我四处张望了，您不是唯一遇到这种情况的人。 尝试使用以下命令删除本地编译的资产： git rm -r public/assets然后推送至heroku。 保留对production.rb所做的更改。

我在StackOverflow上看到了您的帖子，很棒！ 我喜欢看到人们在社区中互相帮助。 您还记得上次造成问题的原因吗？ 它是：

ActionView :: Template :: Error（未预编译home.css）：并且您需要将home.css添加到config / environments / production.rb。 您需要告诉production.rb您需要home.css。 您需要告诉您需要除application.css以外的其他CSS文件。

现在，部署后您在日志中看到什么错误？

ActionView :: Template :: Error（layout.css未预编译）：知道了吗？ 现在，您还需要添加layout.css。 您可以像这样简单地添加：

％w（home.css layout.css）再次，您需要将除了application.css之外的所有其他CSS添加到config / environments / production.rb中。 如果除了application.js之外，还需要添加一些js文件，则还需要添加到config / environments / production.rb。 我可以看到，您需要在应用程序中添加很多CSS文件（例如，对于CSS来说，为college_pages，论文，about_college等，对于js为about_college）。 读取日志是调试和编程的第一步。 日志总是告诉您一些信息（如果没有日志，我将无法指出您的问题！）。 很抱歉，我没有告诉您如何查看日志（似乎您不知道该如何做）。

这是读取日志的用法：

用法：heroku日志

显示最近的日志输出

-n，--num NUM＃显示的行数-p，--ps PS＃仅显示给定进程的日志-s，--source SOURCE＃仅显示给定源的日志-t，--tail ＃持续流式传输日志

例：

$ heroku日志2012-01-01T12：00：00 + 00：00 heroku [api]：配置通过email@example.com添加示例2012-01-01T12：00：01 + 00：00 heroku [api]：版本v1您可以执行heroku logs -n 100之类的操作来查看最近的100行日志。

希望这会有所帮助，惠子

非常感谢你的帮助！ 我知道您有点超出您的责任，对此我深表感谢。

我将所有其他css和js文件添加到production.rb中，并成功部署！ 我感到困惑的原因是我没有意识到我必须将所有这些都包含在production.rb中。 我出于某种原因认为application.css和application.js做到了这一点，所以我不必这样做，并且出于某种原因，我认为home.css是个例外。
