  • I was having this issue on mac and this worked for me, I used the Terminal to disable ipv6 temporarily: **Disable** `networksetup -setv6off Ethernet && networksetup -setv6off Wi-Fi` - **Enable**: `networksetup -setv6automatic Wi-Fi && networksetup -setv6automatic Ethernet` – polloss Mar 14 '23 at 16:28

Specify the source with the command,

    gem install <gem_name> --source http://rubygems.org
