ruby-on-rails - 让 less-rails 添加行号作为注释
有什么方法可以配置less-rails，以便将原始来源的行号显示为注释？是否可以启用源映射？
考虑以下示例：
文件1.less
文件2.less
应用程序.css.less
我得到什么：
我想要的是
或者有没有其他更简单的方法来找出哪个规则属于哪个文件？
更新
配置我的应用程序时，config.less仅包含以下内容：
ruby-on-rails - 预编译资产轨道时更少的解析器错误
这是我的 Gemfile。
我的 application.rb 文件中有这个
当我尝试使用 rake 资产预编译我的资产时，我的资产中有 scss 和 less 文件：precompile 我收到此错误
我在这里做错了什么有什么帮助吗？
ruby - Less::Error 预期的 ')' 得到了 '''
最近我将 less-rails gem 升级到 3.0.0。在 stylesheet_link_tag、javascript_include_tag、image_tag 和其他任何涉及资产管道的地方引发的错误。
但是，当我添加 /assets/ 例如从更改
= stylesheet_link_tag "application"为= stylesheet_link_tag "/assets/application"它时，它可以工作。

我尝试一一删除 css 和 js 文件，但似乎问题不在于文件。任何想法？

ruby-on-rails - 由于将 rails 从 3 迁移到 5，升级配置更少
从 v3 到 v5 的 Rails 迁移正在进行中。较少的加载是行不通的。
（错误消息中似乎有奇怪的 mime 类型，我想可能less必须在那里）
实际上文件存在并且在迁移之前一切都已经工作，根据迁移过程的文档执行捆绑和代码更改
也是这样配置的环境
有什么建议可以弄清楚吗？任何额外的调试/检查请求？
谢谢
