Vue项目构建方法4：vue ui 可视化构建 C:\Users\Mac\Documents\newlifewyq\技术精英-source\vue\vue3pro>vue ui #执行该命令，看到下面弹出的地址，访问下面的地址，就是一个用浏览器访问的项目构建站点，可以选择项目目录，包管理工具等，新建一个项目，新建完成后，我们可以用可视化的方式运行（相当于在项目根目录执行 npm run serve）我们可以终止当前的交互命令ctry+c，注意终止后，项目管理可视化工具将不可用，当然我们还可以重新用vue ui打开该可视化工具，通过项目管理页面-导入项目，来重新管理某个vue项目。 ��� Starting GUI... ��� Ready on http://localhost:8001
运行项目：单击任务-运行即可，本vue ui 可视化页面可以管理多个项目，我们每次需要用可视化方式来管理依赖（安装依赖等），插件的时候，就可以直接输入 vue ui,然后访问生成的管理网址，浏览器访问该网址，然后在项目管理页面，选择导入，就可以导入项目，进行管理，比如运行，安装依赖等。看下面的截图，我们开启了创建的项目，地址是 http://localhost:8080,我们在资源管理找到该目录地址，在dos窗口cd进入该项目目录，用npm run serve 命令行也可以继续管理开发项目。 |
