Heroku预编译资产失败

Question

更新后，我的应用程序突然无法运行。 不确定出了什么问题。 基本上，当我推送到heroku时，我得到这些错误：

Precompiling assets failed, enabling runtime asset compilation
Injecting rails31_enable_runtime_asset_compilation

再高一点：

   rake aborted!
   Unexpected token: operator (>) (line: 19073, col: 9, pos: 605247)

当我实际加载网站时（“我们很抱歉，但出现问题”），并查看heroku日志，我得到了这个：

Load path: /app

（Kreon是一个额外的字体，我添加了一段时间后工作正常.custom.css.scss是我的主要css文件，第一行是我导入bootstrap的方式，没有改变，并且永远工作）。

我搜索了如何处理“导入未找到或不可读的文件：bootstrap”错误，并着手进行此讨论并检查了相关的heroku疑难解答页面 ，但在我的production.rb文件中将assets.compile更改为true导致上面的heroku推送错误，并且疑难解答页面似乎与我的具体问题没有多大关系。 不太确定这里发生了什么，所以我将在下面提出一些可能相关的代码。

真正抛弃我的那一行是我的heroku推送日志中的这一行：

Unexpected token: operator (>) (line: 19073, col: 9, pos: 605247)

问题是，我不知道在这个麻烦的“>”中要查找哪个文件。 任何想法如何阅读该行/ col / pos命名法来查找实际的违规代码片段？

谢谢。

Answer 1

使用app/assets/stylesheets/custom.css.scss第1行进行STart并查找错误> 。 还要确保application.scss符合您的期望。

也只是将custom.css.scss重命名为custom.scss Heck，可能会这样做。

Answer 2

同样的事情发生在我身上，
“预编译资产失败了。” 在推向heroku的同时
在我的开发环境中，我的css出错了：
” .........
cursor：指针
颜色：＃808080;“

错过了“;” 在“指针”之后，开发环境并不介意错误，但Heroku的PreCompile任务确实如此。

其他一些问题可能是由重复的命名文件引起的，带有“css”和“css.scss”后缀。

Answer 3

在终端试试这个：

rake assets:precompile RAILS_ENV=production --trace

比试图推动heroku更好。

我只是犯了同样的错误。 问题是：

• 设计的config.secret_key被评论
• javascript文件中的syntax_error（for循环中的“of”而不是“in”）
