更新 2021-09-08:TL;DR。 Tailwind 未应用于 HAML 模板。
将项目迁移到 shakapacker
,它在底层使用 webpack@v6
和 postcss
。除了 TailwindCSS 之外,所有其他前端 CSS 资源似乎都已正确加载。
为了使调试更简单,我从主文件中删除了除 Tailwind 之外的所有其他 CSS 导入。我还创建了以下测试 HTML 页面来查看是否应用了 Tailwind CSS 样式。
test.html
...
<div class="max-w-sm rounded overflow-hidden shadow-lg">
<div class="px-6 py-4">
<div class="font-bold text-xl mb-2">
The Coldest Sunset
</div>
<p class="text-gray-700 text-base">
Lorem ipsum
</p>
</div>
</div>
...
当我查看此页面时,它看起来很简单,只有文本 - 没有应用阴影、填充、字体粗细等。当我查看生成的 CSS 输出时,似乎只加载了 Tailwind 的重置样式,没有加载其他内容。

按照下面的评论建议,我运行了 yarn run tailwindcss -i ./app/assets/packs/styles/application.scss -o ./output.css
并产生了以下错误:
.../app/assets/packs/styles/application.scss:4:1: Unknown word
You tried to parse SCSS with the standard CSS parser; try again with the postcss-scss parser
该错误指向第一个注释掉的行: //@tailwind "base";
这是有道理的,因为 //双正斜杠注释
是 SASS/SCSS
功能,而不是标准 CSS
。
但是,我认为包含 sass
和 sass-loader
可以根据 shakapacker
安装说明来处理此问题。
因此,我在 webpack.config.js
中明确指定了加载器(见下文),但错误仍然发生。
我已包含以下所有相关文件。
配置文件
application.scss
(导入所有 CSS 资源):
@import "tailwindcss/base";
@import "tailwindcss/components";
@import "tailwindcss/utilities";
// @tailwind "base";
// @tailwind "components";
// @tailwind "utilities";
使用@import
或@tailwind
会产生相同的结果。
application.js
(导入application.scss
)
我只包含了相关的代码行。
...
import "./styles/application.scss"
...

最佳答案
所以,经过一番寻找之后,罪魁祸首就在 tailwind.config.js
文件中。我没有提及我正在使用 HAML
模板,并且忘记将 *.haml
扩展添加到 tailwind 配置中。
我将更新原始问题,以便将 HAML 作为问题的一部分。
解决方案如下。
const plugin = require('tailwindcss/plugin')
module.exports = {
content: [
...
'./app/views/**/*.html.haml',
'./app/views/**/*.haml',
...
],
plugins: [
...
]
}
关于ruby-on-rails - tailwind 3 未在 Rails + shakapacker + HAML 中完全加载(webpacker@v6、webpack@v5、postcss@v8),我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/73311322/
