Question

我正在一个新项目中使用Vue CLI 3和Vuetify 2.1，最近又钻研了覆盖Vuetify's SASS variables。最终使它工作后，我意识到每次修改创建的variables.scss文件并重新编译项目时，完成编译都需要5分钟左右。我尝试更新package.json脚本来增加Node正在使用的内存，并且虽然修复了我收到的导致编译崩溃的错误，但现在编译时间非常慢。显示的进度（我正在使用Foreman同时运行我的Rails API和Vue服务器）看起来像这样：

17:47:29 web.1  | <s> [webpack.Progress] 69% building 916/930 modules 14 active /<path/to/app>/frontend/node_modules/css-loader/index.js??ref--9-oneOf-3-1!/<path/to/app>/frontend/node_modules/postcss-loader/src/index.js??ref--9-oneOf-3-2!/<path/to/app>/frontend/node_modules/sass-loader/lib/loader.js??ref--9-oneOf-3-3!/<path/to/app>/frontend/node_modules/vuetify/src/components/VSwitch/VSwitch.sass

如我所说，这些进度加载大约要持续五分钟，直到它最终完成。我的猜测是，因为我更新了一个变量，所以必须为Vuetify node_module中的每个组件和该变量的实例更新该样式。

我的问题是是否有任何方法可以加快速度？也许我设置了导致此问题的错误信息？还是这完全正常，我只需要处理它？</ p>

@import '~vuetify/src/styles/main.sass';

这会将相当数量的CSS注入每个sass文件的顶部，因此重复了数百次。变量文件不应包含任何输出实际样式的代码-仅允许变量，mixin和函数。

修改变量文件时

30+秒是正常的，因为您猜想在这种情况下它必须重新编译所有内容。从vuetify/lib/framework而不是vuetify/lib导入可以通过仅在开发包中包括使用过的组件来加快此速度。

Vuetify 2.1和Webpack的编译时间非常长
