如何导出全局scss变量文件以导入到Rails 6 Webpacker中的所有scss文件

2024-04-29 • 问答

我们正在从资产管道迁移到Webpacker，我试图寻找一个确定的答案长达数小时，但找不到“正式方法”来将全局scss变量文件用于我的应用程序中的所有scss文件

例如，我有一个文件colors.scss

$gray: #000000;
$red: #EF6461;

＆我希望所有webpacker scss文件都可以使用这些scss变量，当前我已将该文件导入到application.scss中，但是在每个scss中都出现错误，因为它找不到这些变量，因为我知道webpacker会相互独立地转换scss文件，因此看不到我在application.scss中导入的变量文件

那么如何处理此问题，使全局配置文件可用于webpack（或webpacker）配置本身中的所有scs，而不是手动在每个scss中导入配置文件？

注意：在每个scss中导入配置文件都可以解决此问题，但是它具有重复性和脆弱性

为了解决这个问题，我在进行不同的试验时遇到了不同的编译错误：

1-如果我将样式表保留在webpacker packs文件夹中，那么我从所有scss文件中都会收到许多错误消息，他们不知道我正在使用的scss变量（此问题的核心）

这样的错误：

ERROR in ./app/javascript/packs/stylesheets/components/blog-pages/_blog-index.scss
Module build failed (from ./node_modules/mini-css-extract-plugin/dist/loader.js):
ModuleBuildError: Module build failed (from ./node_modules/sass-loader/dist/cjs.js):
SassError: Undefined variable: "$green".
        on line 16 of xxxxxxx/app/javascript/packs/stylesheets/components/blog-pages/_blog-index.scss
>>      color: $green;

   ---------^

2-如果我将样式表放在packs文件夹旁边，则类似的scs会出现其他1比1错误：

    ERROR in ./app/javascript/stylesheets/application.scss
Module build failed (from ./node_modules/mini-css-extract-plugin/dist/loader.js):
