Heroku预编译资产失败
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) Error at new JS_Parse_Error (/tmp/execjs20121211-811-1z5vum.js:1720:22) at js_error (/tmp/execjs20121211-811-1z5vum.js:1728:15) at croak (/tmp/execjs20121211-811-1z5vum.js:2189:17) at token_error (/tmp/execjs20121211-811-1z5vum.js:2196:17) at unexpected (/tmp/execjs20121211-811-1z5vum.js:2202:17) at /tmp/execjs20121211-811-1z5vum.js:2580:17 at maybe_unary (/tmp/execjs20121211-811-1z5vum.js:2665:27) at expr_op (/tmp/execjs20121211-811-1z5vum.js:2685:45) at expr_ops (/tmp/execjs20121211-811-1z5vum.js:2692:24) at maybe_conditional (/tmp/execjs20121211-811-1z5vum.js:2696:28)
当我实际加载网站（“我们很抱歉，但出现问题”），并查看heroku日志时，我得到了这个：
Load path: /app 2012-12-11T23:18:13+00:00 app[web.1]: 8: "all" %> 2012-12-11T23:18:13+00:00 app[web.1]: (in /app/app/assets/stylesheets/custom.css.scss)): 2012-12-11T23:18:13+00:00 app[web.1]: 6: 2012-12-11T23:18:13+00:00 app[web.1]: ActionView::Template::Error (File to import not found or unreadable: bootstrap. 2012-12-11T23:18:13+00:00 app[web.1]: 5:
（Kreon是我添加了一段时间的另一种字体，它一直工作正常.custom.css.scss是我的主要css文件，第一行是我以一种没有改变并永久工作的方式导入bootstrap的地方）。
我搜索了如何处理“导入未找到或无法读取的文件：bootstrap”错误，并登陆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。 不确定这里发生了什么，所以我只想在下面放一些可能相关的代码。

在我的heroku推送日志中，真正抛弃我的那一行是：
Unexpected token: operator (>) (line: 19073, col: 9, pos: 605247)
问题是，我不知道要查找这个麻烦的“>”的文件。 任何想法如何阅读该行/ col / pos命名法以找到实际的违规代码片段？
谢谢。
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。
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中出错：
” ………
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。
在终端试试这个：
rake assets:precompile RAILS_ENV=production --trace
比试图推进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”）
