Rails / Heroku问题

Question

我在Heroku上运行应用程序时遇到麻烦。 该应用程序在本地运行良好，并且在我推送时没有出现任何错误。

我有点菜鸟，但是这里有日志。...我到底在做什么错？ 我确定有几件事；）

谢谢！

Answer 1

在索引的第5行上使用<%= javascript_include_tag "application" %> 。

Answer 2

失误

为了给您更多有关在Heroku上运行应用程序的信息，您将遇到两种错误：

Heroku

滑轨

这些错误将在您尝试加载Heroku应用程序（ http://***.herokuapp.com ）时显示，并且相对容易解码。

• Rails错误是由于您自己的代码而发生的（通常是语法错误）。
• 由于您如何设置Heroku环境而发生Heroku错误（IE平台错误）

区别在于，如果您遇到Rails错误，则您的应用程序可以在Heroku上正确运行-只是存在很多内部问题，可能与语法有关。 如果看到Heroku错误，则从本质上讲这意味着您没有正确设置Heroku的平台（通常没有db ），这意味着您必须在Heroku上进行工作才能对其进行整理。

---

日志

您暗示的问题是Rails问题，因为您可以在日志中查看有关错误可能的详细信息。 重要说明是Heroku错误通常不会在您的日志中报告任何内容（但这是另一回事）

我强烈建议您使用LogEntries附加组件 ：

安装此程序，然后在后端使用“实时”功能，可以使您更好地消化收到的错误。 至少它对我们有帮助

-

阅读日志本身就是一门艺术。 通常，您会寻找特定的“错误”消息-但是这样做可能非常困难。 我阅读日志的方式如下：

浏览您的附件后，我发现以下行：

ActionView::Template::Error (defaults.js isn't precompiled):

这应该是错误（尽管它可能是另一个错误的一部分）。 它说明您的app/assets/javascripts/文件夹中没有defaults.js ； Jade McGough正确指出的含义，这意味着您需要引用“应用程序” JS文件

Answer 3

请用第5行替换以下代码：

并在项目路径上运行“ heroku run rake asset：precompile”此命令
