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

也许我没有进口东西而且我不知道遗失了什么。我尝试将foundation.scss导入styles.scss，所以我只将所有的foundation.scss放入styles.scss并更改了路线，但它无法正常工作

Answer 1

在每个角度组件中，您需要包含您使用的任何变量

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 ，这样您就可以导入＆＃34;设置＆＃34;而不是指定完整路径，但您仍然必须在任何地方导入该文件
