二、创建vue_test项目

在电脑桌面创建vue_test工程。

2.1 cmd进入桌面

打开cmd窗口，输入进入电脑桌面输入命令：cd des，然后按在Tab键，会自动进行代码补全，变成了cd Desktop，然后回车。

Microsoft Windows [版本 10.0.22621.2134]
(c) Microsoft Corporation。保留所有权利。

C:\Users\nash_>cd Desktop

C:\Users\nash_\Desktop>

2.2 创建项目

输入以下命令：vue create vue_test回车，然后选择Vue2回车.

C:\Users\nash_>cd Desktop

C:\Users\nash_\Desktop>vue create vue_test

Vue CLI v5.0.8
? Please pick a preset:
  Default ([Vue 3] babel, eslint)
> Default ([Vue 2] babel, eslint)
  Manually select features

之后，提示安装成功，并告诉你进入到目录cd vue_test，然后执行命令npm run serve。此时关闭cmd窗口。
