问题描述
我在添加 SVG.js 库时遇到了一个大问题。就像我不做一样,我仍然画不出任何东西:(

import Vue from 'vue'
import App from './App.vue'
import router from './router'
import { SVG } from '@svgdotjs/svg.js'

Vue.use(SVG);

new Vue({
router,SVG,render: h => h(App)
}).$mount('#app')

<script>
import axios from "axios";
import { SVG } from '@svgdotjs/svg.js'
export default {
data() {
return {
}
},created() {
var draw = SVG().addTo('drawing').size(400,400)
var rect = draw.rect(100,100)
},methods: {
}
}
</script>
编译失败。
./src/components/Picture.vue 模块错误(来自 ./node_modules/eslint-loader/index.js):
D:\inzynierka\projekt\src\components\Picture.vue 41:17 错误 'rect' 被赋值但从未使用过 no-unused-vars
✖ 1 个问题(1 个错误,0 个警告)
解决方法
在代码中任何地方声明但未使用的变量很可能是由于重构不完整而导致的错误。此类变量会占用代码中的空间,并可能导致读者混淆。
var rect = draw.rect(100,100)
矩形未使用。
如果你想忽略它。你可以这样做
// eslint-disable-next-line no-unused-vars
var rect = draw.rect(100,100)
