我的应用在更新后突然无法正常工作。不确定出了什么问题。基本上，当我推送到heroku时，我得到了这些错误：
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，但出现了问题”），并查看了heroku日志，我明白了：

（Kreon是我添加了一段时间以后工作正常的附加字体.custom.css.scss是我的主要css文件，第一行是我导入bootstrap的方式，没有改变并且已经工作永远）。
我搜索了如何处理“导入未找到或不可读的文件：bootstrap”错误，并登陆this discussion并检出relevant heroku troubleshoot page，但将assets.compile更改为true in我的production.rb文件导致上面的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“＆gt;”中要查找哪个文件。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？
感谢。
答案 0 :(得分：3)
使用app/assets/stylesheets/custom.css.scss的第1行进行展示，并查找错误的>。
还要确保application.scss符合您的期望。
同样只需将custom.css.scss重命名为custom.scss Heck，即可。
答案 1 :(得分：0)
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中出现了错误：
“.........
光标：指针
颜色：＃808080;“
错过了“;”在“指针”之后， 开发环境不介意错误， 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，后缀为“css”和“css.scss”。
答案 2 :(得分：0)
在终端试试这个：
rake assets:precompile RAILS_ENV=production --trace
比试图推进heroku更好。
我遇到了同样的错误。 问题是：
