克隆到本地： git clone https://gitee.com/renrenio/renren-fast-vue.git
git clone https://gitee.com/renrenio/renren-fast.git
将拷贝下来的“renren-fast”删除“.git”后，拷贝到“gulimall”工程根目录下，然后将它作为gulimall的一个module
创建“gulimall_admin”的数据库，然后执行“renren-fast/db/mysql.sql”中的SQl脚本 修改“application-dev.yml”文件，默认为dev环境，修改连接mysql的url和用户名密码
spring:
datasource:
type: com.alibaba.druid.pool.DruidDataSource
druid:

url: jdbc:mysql://192.168.137.14:3306/gulimall_admin?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai
username: root
password: root
启动“gulimall_admin”，然后访问“http://localhost:8080/renren-fast/” 
安装node.js，并且安装仓库 npm config set registry http://registry.npm.taobao.org/ 分别执行 npm install npm run dev

常见问题1：“Module build failed: Error: Cannot find module 'node-sass” 运行过程中，出现“Module build failed: Error: Cannot find module 'node-sass’报错问题”，解决方法
用npm install -g cnpm --registry=https://registry.npm.taobao.org ，从淘宝镜像那下载，然后cnpm下载成功。 最后输入cnpm install node-sass --save。npm run dev终于能跑起来了！！！ 原文链接：https://blog.csdn.net/qq_38401285/article/details/86483278
常见问题2：cnpm - 解决 " cnpm : 无法加载文件 C:\Users\93457\AppData\Roaming\npm\cnpm.ps1，因为在此系统上禁止运行脚本。有关详细信息 。。。 " https://www.cnblogs.com/500m/p/11634969.html
所有问题的根源都在“node_modules”，npm install之前，应该将这个文件夹删除，然后再进行安装和运行。 再次运行npm run dev恢复正常：
