我在d盘创建了一个文件夹：
执行命令
npm uninstall -g vue-cli
npm install -g @vue/cli
创建项目
vue create my-project
回车，我们用vue2
回车，我们用yarn试一下。（后面我再创建就成默认此种方式了）
根据提示输入命令
PS D:\code\testvue> cd my-project
PS D:\code\testvue\my-project> yarn serve
注意：这里以前是用npm run dev
http://localhost:8080/
打开VSCode，
这个是yarn生成的
这个是我之前用npm生成的项目结构，还是有些区别的
常见命令
npm install => yarn install
npm install --save [package] => yarn global add [package]
npm install --save-dev [package] => yarn add [package] --dev
npm install --global [package] => yarn global add [package]
npm uninstall --save [package] => yarn remove [package]
npm uninstall --save--dev [package] => yarn remove [package] –dev
