我已经按照以下说明设置了Grunt工作流程： https://devdocs.magento.com/guides/v2.3/frontend-dev-guide/css-topics/css_debug.html
我的local-themes.js看起来像这样：
➜ m2 git:(master) ✗ cat dev/tools/grunt/configs/local-themes.js
'use strict';
module.exports = {
ac_default: {
area: 'frontend',
name: 'Ac/Default',
locale: 'en_US',
files: [
'css/source/_extend',
],
dsl: 'less'
},
ac_retail: {
area: 'frontend',
name: 'Ac/Retail',
locale: 'en_US',
files: [
'css/source/_extend',
],
dsl: 'less'
},
ac_wholesale: {
area: 'frontend',
name: 'Ac/Wholesale',
locale: 'en_US',
files: [
'css/source/_extend',
],
dsl: 'less'
}
};
当更改子主题中的较少文件时，我的咕unt声观看成功触发：

不幸的是，styles-m.css或styles-l.css文件未更新。因此，当我刷新页面时，较少文件中所做的更改不会反映在页面上。
我在Magento错误跟踪器中发布了一个票证，但它们并没有特别帮助。

我的问题是。这里有没有人使用Grunt为具有多个子主题的设置减少编译次数？
在我的情况下，预期的主题继承如下：
据我所知，Grunt工作流是唯一真正适合主题开发的工作流。服务器和客户端的编译速度太慢，无法用于开发。

最后弄清楚了。该文档有错误。您需要指定父主题样式文件，即使您的子主题具有它自己的根源文件，如果要在子主题较少的文件更改时重新编译styles-m.css和styles-l.css，则也需要指定它们。这个local-themes.js最终为我工作：
>>'use strict';
>>module.exports = {
ac_default: {
area: 'frontend',
name: 'Ac/Default',
locale: 'en_US',
files: [
'css/styles-m',
'css/styles-l',
],
dsl: 'less'
},
ac_retail: {
area: 'frontend',
name: 'Ac/Retail',
locale: 'en_US',
files: [
'css/styles-m',
'css/styles-l',
],
dsl: 'less'
},
ac_wholesale: {
area: 'frontend',
name: 'Ac/Wholesale',
locale: 'en_US',
files: [
'css/styles-m',
'css/styles-l',
],
dsl: 'less'
}
};

添加
'css/styles-m',
'css/styles-l',
也为我修复了它。谢谢你
