SassError:`darken($color, $amount)` 的参数`$color` 必须是一种颜色 [英] SassError: argument `$color` of `darken($color, $amount)` must be a color

问题描述

我正在尝试使用以下 SCSS 代码在 Bulma 中添加自定义颜色映射:

//设置颜色$primary: #5B43CC;$primary-invert: findColorInvert($primary);$推特:#4099FF；$twitter-invert: findColorInvert($twitter);$facebook:#4267B2；$facebook-invert: findColorInvert($facebook);$自定义颜色:(foo":(黑色，灰色)，);//导入布尔玛的核心@import "~bulma/sass/utilities/_all";//链接$link: $primary;$link-invert: $primary-invert;$link-focus-border: $primary;//导入 Bulma 和 Buefy 样式//this 已经移到 App.vue 因为它必须在最后@import "~bulma";@import "~buefy/src/scss/buefy";

但我收到以下错误:

但是，如果我注释掉 //$primary-invert: findColorInvert($primary); 那么错误就会消失.此外，如果 //set your colours 下的代码段在 @import "~bulma/sass/utilities/_all" 之后移动，那么错误也会消失.>

我在这里做错了什么?

注意，这是对这个的后续以前的帖子

解决方案

所以正如我在评论中提到的，当谈到 Sass 编译时，它完全是关于排序(imports 和/或变量声明).现在，由于这些颜色反转正在使用名为 nofollow 的 Bulma 实用程序findColorInvert 位于 utilities/functions.sass 中，我们可能无法使用 utilities"https://github.com/jgthms/bulma/blob/master/sass/utilities/_all.sass" rel="nofollow noreferrer">原始订单在这里.

我们可以拆分它们并在 functions 和 derived-variables 之间插入我们的习惯:

@import "~bulma/sass/utilities/initial-variables";@import "~bulma/sass/utilities/functions";//设置颜色$primary: #5B43CC;$primary-invert: findColorInvert($primary);$推特:#4099FF；$twitter-invert: findColorInvert($twitter);$facebook:#4267B2；$facebook-invert: findColorInvert($facebook);//链接$link: $primary;$link-invert: $primary-invert;$link-focus-border: $primary;$自定义颜色:(foo":(黑色，灰色)，);@import "~bulma/sass/utilities/derived-variables";@import "~bulma/sass/utilities/animations";@import "~bulma/sass/utilities/mixins";@import "~bulma/sass/utilities/controls";

I am attempting to add a custom color map in Bulma, with the following SCSS code:

// Set your colors
$primary: #5B43CC;
$primary-invert: findColorInvert($primary);
$twitter: #4099FF;
$twitter-invert: findColorInvert($twitter);
$facebook: #4267B2;
$facebook-invert: findColorInvert($facebook);

$custom-colors: (
  "foo": (black, grey),
);

// Import Bulma's core
@import "~bulma/sass/utilities/_all";

// Links
$link: $primary;
$link-invert: $primary-invert;
$link-focus-border: $primary;

// Import Bulma and Buefy styles 
// this has been moved to App.vue because it must be at the end
@import "~bulma";
@import "~buefy/src/scss/buefy";

But I get the following error:

 ERROR  Failed to compile with 6 errors                                                                                                           1:26:26 AM

However, if I comment out // $primary-invert: findColorInvert($primary); then the error goes away. Also, if the snippet under // set your colors is moved after @import "~bulma/sass/utilities/_all", then the error also goes away.

What am I doing wrong here?

Note, this is a follow-up to this previous post

解决方案

So as I mentioned in the comments, when it comes to Sass compilation it's all about ordering (of imports and/or variable declarations). Now, since those color inversions are using a Bulma utility called findColorInvert, which resides within utilities/functions.sass, we can't probably import the utilities with the original order here.

We could split them and insert our customs in between the functions and derived-variables:

@import "~bulma/sass/utilities/initial-variables";
@import "~bulma/sass/utilities/functions";

// Set your colors
$primary: #5B43CC;
$primary-invert: findColorInvert($primary);
$twitter: #4099FF;
$twitter-invert: findColorInvert($twitter);
$facebook: #4267B2;
$facebook-invert: findColorInvert($facebook);

// Links
$link: $primary;
$link-invert: $primary-invert;
$link-focus-border: $primary;

$custom-colors: (
  "foo": (black, grey),
);

@import "~bulma/sass/utilities/derived-variables";
@import "~bulma/sass/utilities/animations";
@import "~bulma/sass/utilities/mixins";
@import "~bulma/sass/utilities/controls";
