在component的style裡面引用css遇到幾個問題
1.路徑問題

<style src="@/assets/css/base.css">

這樣不會報錯
可是如果是

src="./assets/css/base.css"

會報錯

This dependency was not found:
* !!vue-style-loader!css-loader?{"sourceMap":true}!../../node_modules/vue-loader/lib/style-compiler/index?{"vue":true,"id":"data-v-656039f0","scoped":false,"hasInlineConfig":false}!./assets/css/base.css in ./src/components/HelloWorld.vue

To install it, you can run: npm install --save !!vue-style-loader!css-loader?{"sourceMap":true}!../../node_modules/vue-loader/lib/style-compiler/index?{"vue":true,"id":"data-v-656039f0","scoped":false,"hasInlineConfig":false}!./assets/css/base.css

2.使用@import方法

@import '@/assets/css/base.css';
@import './assets/css/base.css';

皆會報錯

Module build failed: Error: Failed to find '@/assets/css/base.css'
@ ./node_modules/vue-style-loader!./node_modules/css-loader?{"sourceMap":true}!./node_modules/vue-loader/lib/style-compiler?{"vue":true,"id":"data-v-656039f0","scoped":false,"hasInlineConfig":false}!./node_modules/vue-loader/lib/selector.js?type=styles&index=0!./src/components/HelloWorld.vue 4:14-312 13:3-17:5 14:22-320

看了很多文章
有些說要在
webpack.base.conf加入module的rules
但版本很多，加了也是報錯
有些說可以直接用
vue cli都有內建css loader跟style loader了
也確認過有這兩個套件了
實在不知道問題點出在哪
