我只想在我的项目中使用 MDL 的布局组件。
所以，在我的app.css文件中，我正在导入这个：
@import url('~material-design-lite/src/layout/_layout.scss');
在构建过程中，我收到以下错误：
ERROR in ./~/css-loader!./~/material-design-lite/src/layout/_layout.scss
Module not found: Error: Cannot resolve 'file' or 'directory' ../variables in /Users/Mitch/Documents/project/web/node_modules/material-design-lite/src/layout
@ ./~/css-loader!./~/material-design-lite/src/layout/_layout.scss 3:10-66
ERROR in ./~/css-loader!./~/material-design-lite/src/layout/_layout.scss
Module not found: Error: Cannot resolve 'file' or 'directory' ../mixins in /Users/Mitch/Documents/project/web/node_modules/material-design-lite/src/layout
@ ./~/css-loader!./~/material-design-lite/src/layout/_layout.scss 4:10-63
_layout.sccs从这些行开始
@import "../variables";
@import "../mixins";
有什么想法我可能做错了吗？

更新
我尝试了@import url('~material-design-lite/src/material-design-lite.scss');，因为这不是部分的，所以在我修改为只导入布局组件之后。
现在我收到以下错误：
ERROR in ./~/css-loader!./~/material-design-lite/src/material-design-lite.scss
Module build failed: Unknown word (19:1)
17 | /* Material Design Lite */
18 |

20 | @import "variables";
21 | @import "mixins";
22 |
@ ./~/css-loader!./public/css/app.css 3:10-114
它在评论上失败了。我不知道如何解决这个问题，我尝试使用postcssandpostcss-scss加载器和postcss-strip-inline-comments插件无济于事；旧的错误只是被新的错误所取代。
