【问题描述】：

我正在尝试在 RoR 6.1.3 和 Ruby 2.7.2 应用程序中安装 Tailwind CSS 2.0。我只是在 localhost 的输出中没有看到任何样式更新，并且除非使用 bin/webpack ，否则会出现任何错误：

./app/assets/stylesheets/application.css 中的错误 (./node_modules/css-loader/dist/cjs.js??ref--5-1!./node_modules/postcss-loader/src??ref--5-2!./app/assets/stylesheets/application .css）模块构建失败（来自 ./node_modules/postcss-loader/src/index.js）：错误：在 [ ...../应用程序/资产/样式表] 在 ..../node_modules/postcss-import/lib/resolve-id.js:35:13 @ ./app/assets/stylesheets/application.css 2:26-171 @ ./app/javascript/packs/application.js

app/javascript/packs/application.js

import '../utils/direct_uploads.js';
ActiveStorage.start()
require("../../assets/stylesheets/application.css")

package.json

/postcss.config.js

module.exports = {
  plugins: [
    require('tailwindcss')('./tailwind.config.js'),
    require('autoprefixer'),
    require('postcss-import'),
    require('postcss-flexbugs-fixes'),
    require('postcss-preset-env')({
      autoprefixer: {
        flexbox: 'no-2009'
      },
      stage: 3
    })
  ]
}

app/assets/stylesheets/application.css

@import "tailwindcss/base";
@import "tailwindcss/components";
@import "tailwindcss/utilities";

application.html.erb

<%= javascript_pack_tag 'application' %>     
<%= stylesheet_link_tag 'application', media: 'all' %>     
<%= stylesheet_pack_tag 'application', media: 'all' %>

在测试页面上我得到了这些错误：

ActionController::RoutingError (No route matches [GET] "/assets/tailwindcss/base"):
ActionController::RoutingError (No route matches [GET] "/assets/tailwindcss/components"):
ActionController::RoutingError (No route matches [GET] "/assets/tailwindcss/utilities"):

我该如何解决？

【问题讨论】：

尝试导入("../../assets/stylesheets/application.css")
不，我总是有同样的错误:(
你在使用 webpacker 吗？包中的 css 需要使用 stylesheet_pack_tag 加载。
是的，在我的 application.html.erb 我有：<%= javascript_pack_tag 'application' %> <%= stylesheet_link_tag 'application', media: 'all' %> <%= stylesheet_pack_tag 'application', media: 'all' %>
只保留带有样式表包标签的那个。 stylesheet_link_tag 用于资产管道。

【解决方案1】：

像这样导入你的 postcss 插件能解决你的问题吗？

module.exports = {
  plugins: {
    tailwindcss: {},
    autoprefixer: {},
    ...
  },
}
