【问题描述】:
我最近将我的项目从 Angular 版本 7 升级到了 8。但是当我发出命令 npm start 时,我看到了很多与 Bootstrap 相关的警告。
WARNING: You probably don't mean to use the color value gray in interpolation here.
It may end up represented as gray, which will likely produce invalid CSS.
Always quote color names when using them as strings or map keys (for example, "gray").
If you really want to use the color value here, use '"" + $color'.
╷

在此之后编译失败并出现以下错误消息

Compound selectors may no longer be extended.
Consider `@extend .input-no-border, :focus` instead.
