[英]Getting error (Gem::RemoteFetcher::UnknownHostError) while installing Rails or gem update
我想使用 Ubuntu 18.04 LTS 在我的笔记本电脑中安装 Ruby on Rails。 我已经安装了 Ruby，但是当我尝试使用sudo gem install rails安装 Rails 时，我收到错误消息
ERROR: While executing gem ... (Gem::RemoteFetcher::UnknownHostError)
no such name (https://api.rubygems.org/quick/Marshal.4.8/websocket- extensions-0.1.3.gemspec.rz)
谁能帮我？
禁用IPv6并重试。 它应该工作。
