如果你是以下情況的話：
編譯報錯：
This dependency was not found:
* !!vue-style-loader!css-loader?{"minimize":false,"sourceMap":false}!../../node_modules/vue-loader/lib/style-rewriter?{"id":"data-v-6c96342b","scoped":false,"hasInlineConfig":false}!stylus-loader?{"sourceMap":false}!../../node_modules/vue-loader/lib/selector?type=styles&index=0!./navs.vue in ./src/components/navs.vue
To install it, you can run: npm install --save !!vue-style-loader!css-loader?{"minimize":false,"sourceMap":false}!../../node_modules/vue-loader/lib/style-rewriter?{"id":"data-v-6c96342b","scoped":false,"hasInlineConfig":false}!stylus-loader?{"sourceMap":false}!../../node_modules/vue-loader/lib/selector?type=styles&index=0!./navs.vue
解決方法: 哈哈乳规，在package.json 中的 "dependencies" 中 添加 "stylus": "^0.54.5",然后npm install 就可以了。
