大家好，我是烤鸭：

       采坑实录。

       安装 YAPI 接口项目时出现的这个问题，如果你不是这个情况出现的这个报错，就不用继续看了。

       YAPI的 github 地址:

       https://github.com/YMFE/yapi

 

1.场景

     安装 YAPI 接口项目。当时日志没找，从github的看到有人提的issue，跟我的一样，如下。

3.原因及解决方案

      这个错误的原因在于 nodejs 的 运行权限和运行 yapi -server 的权限不一致。

      解决：

chown -R root:root /nodejs安装目录(环境变量配置的目录)
