安装问题请看这里

1. 确保 node 版本=> 7.6,请运行 node -v 查看版本号
2. 确保 mongodb 版本 => 2.6，请运行 mongo --version 查看版本号
3. 确保安装了 npm, 运行 npm -v 查看版本号
4. 确保安装了 git,运行 git --version 查看版本号
5. 确保安装了 node-gyp 环境，配置方法

确认版本号没问题，请删除原有的安装文件和数据库，重新安装。

如果安装了 yapi-cli 工具，执行 yapi server 找不到命令，可尝试执行 yapi-cli server

如果是使用了yapi server 可视化部署出的问题，可查看下文档-> 内网部署方式，熟悉 docker 童鞋可以使用 docker 部署，docker 部署的教程可以在 https://github.com/YMFE/yapi 这里找到。

如果还是无法安装，请不要选择最新的版本，可选择上一个版本或上上一个版本等，最新版本出问题的概率会比较大。

有问题请在下面留言，感谢大家的反馈。

问题解决，错误原因在于nodejs的用户权限和用户组与yapi不一致，chown到root就可以了
