我无法安装bundler。我使用的是Ubuntu 18，并已安装ruby 2.5.1。下面是运行该命令的输出结果：

gem install bundler --debug

运行 sudo gem install bundler 命令会输出 sudo: gem: 命令未找到

你能从这台机器上访问 https://rubygems.org 吗？因为出现了“无法从 https://rubygems.org/ 下载数据 - 超时”的错误。 - D1ceWard
curl https://rubygems.org 看起来工作正常。它会输出一些HTML。 - Ilya Kushlianski
是的，它输出了一些经过gzip压缩的内容，没有错误。 - Ilya Kushlianski
奇怪，你能成功地运行 gem install whatever 吗？ - D1ceWard

我在rubygems帮助中心找到了类似的问题，http://help.rubygems.org/discussions/problems/31074-timeout-error 这似乎是一个ipv6解析问题。 - D1ceWard

尝试在您的Ubuntu上禁用IPv6。
这就是答案。它现在可用了，谢谢。 根据这篇文章 https://www.admintome.com/blog/disable-ipv6-on-ubuntu-18-04/，只要我重新启动，ipv6 就会被启用。这是我应该期待的吗？我不想在将来禁用 ipv6。 - Ilya Kushlianski
真疯狂，一年过去了，这个问题仍然存在。 - user1142217
同样适用于Windows 10。在禁用IPv6之前，无法安装gems。 - Phrogz
