027-Host is down问题解决

一、sudo gem install cocoapods-repo-svn

我们要sudo gem install cocoapods-repo-svn时，出现错误

ERROR: While executing gem ... (Errno::EHOSTDOWN)
Host is down - send(2)

这时：

cat /etc/resolv.conf

发现有nameserver 192.168.2.7

然后

open /etc/

找到resolv.conf

然后显示原文件。

把原文件复制拖到桌面，修改，不要nameserver，或者注释掉。

修改完成后，放回原位置并且覆盖。

再次执行sudo gem install cocoapods-repo-svn

问题解决：
