我已经运行了 importmaps rake 任务并添加了

sassc-rails

来编译我的 CSS 文件。它在开发环境中运行良好，但在生产环境中会产生错误。我也跑过

rails assets:precompile

。

我的代码在assets/config/manifest.js

//= link_tree ../images
//= link_directory ../stylesheets .css
//= link_tree ../../javascript .js
//= link_tree ../../../vendor/javascript .js

我的代码在assets/stylesheets/application.scss

@import "bootstrap";
@import "./dashboard.scss";
@import "./sidebar.scss";

对于 rails 7 运行以下命令

rails assets:precompile

这将在您的公共文件夹中创建一个资产文件夹。然后重新启动服务器。
