除非CSS文件扩展名以.css结尾，否则无法从文件URL加载CSS. [英] CSS cannot be loaded from `file:` URLs unless they end in a `.css` file extension
问题描述
我第一次尝试使用sass而不是CSS，但是当我尝试加载样式表时，浏览器告诉我它只能加载.css作为样式表.这是html
i'm trying for the first time to use sass and not css but when i try to load the stylesheet the browser tell me that it can only load .css as stylesheet. Here is the html
<!DOCTYPE html>
<html lang="en" dir="ltr">
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="./index_style.scss">
</head>
<body>
</body>
</html>

推荐答案
SASS是预处理器，浏览器不了解.scss，而仅了解.css.SASS将.scss文件转换为.css.
SASS is a preprocessor, the browser doesn't understand .scss, but only .css. SASS converts .scss files to .css.
可能有一些项目允许从HTTP服务器即时"动态加载.scss文件，但该消息表明您是直接从本地文件系统加载页面.
There may be some projects that allow loading dynamically a .scss file "on the fly" from a HTTP server, but the message indicates that you are loading the page directly from your local file system.
在这种情况下，您需要调用预处理器并将 link 上的 href 指向生成的文件.可以使用命令行命令直接完成操作，并在此处找到说明( https://sass-lang.com/guide )，或者如果您使用的是任务运行程序(例如grunt，gulp等)，那么其中就有Sass的任务.
In that case you need to invoke the preprocessor and point the href on the link to the generated file. It can be done directly with a command line command, with the instructions you can find here (https://sass-lang.com/guide) or if you are using a task runner like grunt, gulp, etc. there are task for Sass in those.
