egg-ci 安装失败

[johnnychq]

egg部署生产时出现问题，直接原因是egg间接依赖了egg-ci，但egg-ci安装失败，windows/mac开发环境均可，但centos不可以，单独cnpm install egg-ci也失败。

运行命令时，直接是root身份，所以不明白为啥postinstall报权限问题

[dead-horse]

Error: EACCES: permission denied, open '/home/cxinscn_cathay_portal/tmp/.travis.yml'

权限问题，你看一下文件系统权限。

能知道是哪个模块在 dependencies 里面写了 egg-ci 么？

[dead-horse]

是你自己在 devDependencies 引的 egg-ci 啊，然后我看生成的 travis 文件地址也是到你的项目目录的。

解决方案：

1. 如果你不需要在 github 上跑 CI，去掉 egg-ci 的引用
2. 生产环境安装的时候 cnpm install --production，不安装 devDepencencies
3. 修正权限问题

[johnnychq]

devDependencies直接依赖了egg-ci，这个是以前脚手架里复制过来的，没特别留意，删除后解决。

但还是不能解释为什么root身份cnpm install egg-ci会报上述错误（但win,mac又没问题）的问题。

------seperate line-------

刚又排查了权限问题，当前用户虽然是root，但当前文件夹的权限为dr-xr-xr-x，所以即使默认root也无法执行。

谢谢dead-horse帮忙排查

其实安装devDependencies是为了浏览器端Antd静态资源编译打包的，我们项目偷懒，服务端依赖和前端依赖没分开。刚才操作的机器是测试环境编译机，做antd静态资源打包的。
