webpack5中的决绝方式

解决方式：vue.config.js文件中加入

devServer:{

    historyApiFallback: true,

    allowedHosts: "all",

  }

const { defineConfig } = require('@vue/cli-service')
module.exports = defineConfig({
  transpileDependencies: true,
  lintOnSave:false,
  devServer:{
    historyApiFallback: true,
    allowedHosts: "all",
  }
})
