使用通用 SonarQube 扫描仪分析我的项目时出现错误。根据文档，这种扫描仪和服务器的组合是兼容的。
版本：
- SonarQube 5.6.4 LTS
- CSS / SCSS / Less 插件 3.0
- SonarQube 扫描仪 2.8
有什么问题？
我有这个代码（typography.scss）：
$rem-base: 16;
@function rem($px, $base: $rem-base) {
@return ($px / $base) * 1rem;
}
@function em($px, $base: $rem-base) {
@return ($px / $base) * 1em;
}
@mixin font-size($px, $base: $rem-base) {
font-size: $px + px;
font-size: rem($px);
}
这是分析的结果。请注意，一些 scss 文件似乎已通过分析：
