矩声mini-ipro3与elementi2区别在于配置、价格。
1、矩声mini-ipro3是矩声旗下mini-i系列解码器的第4代产品,采用33寸彩色液晶显示屏,左边还有一个635mm的单端输出和一个44mm的平衡输耳机接口,右边则是一个多功能按钮/旋钮,价格5000元,性价比高。
2、elementi2是element音频解码播放器的入门机型,采用346英寸全贴合彩色触摸屏,方便用家通过触控屏幕更加灵活便捷地执行各项操作,i2宽度和一代一样,机身深度和厚度都增加了,价格10000元。
element场景黑看不到模型解决方法如下:
1、打开npmielement-ui。
2、在mainjs文件中导入。
3、保存,即可显示样式。Element是一份基于Ubuntu的发行,它面向家庭影院或媒体中心式的个人电脑,这类电脑可拥有十英尺大的用户屏幕并被设计为连接到高清晰度电视,以获取一份数字媒体和因特网体验,而这种体验可以在客厅或娱乐场所舒适地获得。

下面我就为大家分享一篇搭建element-ui的Vue前端工程操作实例,具有很好的参考价值,希望对大家有所帮助。
一、安装npm镜像
(1)下载nodejs, 配置nodejs的环境变量
检测PATH环境变量是否配置了Nodejs,点击开始=》运行=》输入"cmd" => 输入命令"path"
检查Nodejs版本
在命令窗口输入:npm install -g cnpm _registry=https://registrynpmtaobaoorg
二、安装全局vue-cli
(1)npm install -g vue-cli 回车,验证是否安装成功,在命令行中输入vue,出来vue的信息说明安装成功
三、全局安装 vue-cli
(1)npm install --global vue-cli
四、创建一个基于 webpack 模板的新项目
(1)vue init webpack my-project (项目名)
(2)cd my-project
(3)npm install
(4)npm run dev
五、需要安装的环境
(1)npm install sass-loader --save-dev
(2)npm install gulp-sass
(3)npm install --save axios
(4)npm install element-ui -S
(5)npm install vuex --save
六、需要引入的包(element-ui)
(1) import ElementUI from 'element-ui'
(2) import 'element-ui/lib/theme-default/indexcss'
(3) import Vue from 'vue'
(4) 使用:Vueuse(ElementUI)
七、项目代码结构
项目源码:https://githubcom/davis0511/school-ui
