vue3项目新建

ゞ浴缸里的玫瑰 2023-06-17 05:55 9阅读 0赞

### 一. 全局安装vue3 ###

详细步骤详见 ：\[在全局vue2的基础上安装vue3（同时存在两个版本）\](https://blog.csdn.net/Jioho\_chen/article/details/90455778)

*当然可以vue2的基础上直接升级成vue3，这样vue2就不能继续使用了。*

查看本机vue3的版本号：（因为我同时需要使用vue3和vue2，故改变了全局命令的名称）

vue3包含的命令：

### 二. 新建项目 ###

vue3中提供两种新建项目方法：

1.  使用命令行新建

vue create ProjectName  // 文件名 不支持驼峰（含大写字母）

选择自动加入babel和eslint  
或者手动选择  
**我们选择自动加入**

开始下载

等待下载完成

如上图提示命令：`cd libin-test & npm run serve`

进入文件夹 `cd libin-test`，文件目录如下图所示，对比vue2项目 内容精简很多

运行项目`npm run serve`  
**记得不再是vue2的npm run dev 啦**

运行成功，打开地址，如图所示，创建成功

1.  使用vue3特有的图形化工具创建  
    打开命令行直接运行`vue ui`（此vue代表全局的vue3，我本机为vue3命令）  
    ![在这里插入图片描述][20191128093452189.png]  
    自动打开了http://localhost:8000/dashboard页面，如下图所示（因为我之前运行过，所以默认打开这个项目）

选择vue项目管理器回到主页面  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xiMTEzNTkwOTI3Mw_size_16_color_FFFFFF_t_70 8]

点击创建项目，选择路径和名称等

根据自己的喜好，创建项目

此时我的vue版本为  
![在这里插入图片描述][20191128095252323.png]

**之前3.11.0创建项目时一直报错后面给它升级成了最新的4.1.1创建成功！**

直接在图形化界面打开项目：
