vue 打包部署子目录后 elementUI icon 图标不显示

问题 部署后element-icon 请求资源404

解决

修改 vue.config.js (添加前缀路径)

vue.config.js完整代码

'use strict'
const path = require('path')
const _publicPath = '/Pledged/'
const defaultSettings = require('./src/settings.js')

function resolve(dir) {
  return path.join(__dirname, dir)
}

const names = defaultSettings.title // page title
const { name } = require('./package');

const port = 3004 // dev port

// 所有配置项的说明： https://cli.vuejs.org/config/
module.exports = {
  /**
   * 如果您计划在子路径下部署站点，则需要设置publicPath，
   * 在大多数情况下请使用'/' !!!
   * https://cli.vuejs.org/config/#publicpath
