vue项目创建流程

首先，需要先安装node.js和npm，详见如下链接

安装vue-cli

cli全称是command line interface，用于快速搭建vue项目的一个工具。

在这里可以看到目前最新的vue-cli发布版本

执行命令

npm install -g @vue/cli
# OR
yarn global add @vue/cli

不指定版本的话，默认最新版，指定版本的话在组件后面加上@版本号

npm install -g @vue/cli@5.0.8

指定-g（global的首字母）和不指定的区别是

1. 指定了-g，下载的组件库版本全局生效，多个项目使用同一版本
2. 未指定-g，局部生效，下载的组件库在执行命令行的项目，下载的组件库版本只在当前项目中

在大多数情况下，推荐优先使用局部安装（不使用 -g），除非确实需要跨多个项目使用某个工具或库。这样可以更好地管理项目的依赖关系，避免潜在的冲突和版本问题。

查看组件最新版本信息命令

npm view @vue/cli
