Question

我有这个错误，看起来我没有将变量导入组件。但这是我的 style.scss

也许我没有导入某些东西，我不知道缺少什么。我尝试将 foundation.scss 导入 styles.scss，所以我只是将所有 foundation.scss 放入 styles.scss 并更改了路由，但它不起作用

Answer 1

在每个 angular 组件中，您需要包含您使用的所有变量

在您的示例中，您需要将 _settings.scss 导入 login.component.scss 文件

@import "./path/to/_settings.scss"

这是关于此行为的 github https://github.com/angular/angular-cli/issues/1253

您可以在配置（angular-cli 或 webpack）中指定 stylePreprocessorOptions，这样您就可以只导入 "settings" 而不是指定完整路径，但是您仍然必须在使用该文件的任何地方导入该文件
