嘗試在我的 Ubuntu 18.04 VM 中實施快速入門：Compose 和 Rails教程，我無法構建容器
$ docker-compose run --no-deps web rails new . --force --database=postgresql

我發現了許多其他與此類似的問題，但到目前為止它們都沒有奏效。我可以 ping ruby??gems：
$ ping rubygems.org
PING rubygems.org (151.101.1.227) 56(84) bytes of data.
64 bytes from 151.101.1.227 (151.101.1.227): icmp_seq=1 ttl=50 time=57.5 ms
64 bytes from 151.101.1.227 (151.101.1.227): icmp_seq=2 ttl=50 time=55.3 ms
但是 dig 沒有顯示任何東西
$ dig short rubygmes.org
我怎樣才能讓 Bundler 能夠從 ruby??gems 中獲取規格？
uj5u.com熱心網友回復：
rubygmes.org似乎在您的 Gemfile 中拼寫錯誤！試試rubygems.org:)
