python - 尝试从 azure 管道中的 ubuntu 虚拟机运行 'conda install python=3.7' 时，Conda 超时

Question

作为 azure 构建管道的一部分在 azure 虚拟机上运行时，为什么 conda 无法完成更新？

它将在此停止，直到 60 分钟超时。

谢谢C.B.和 Merv 。将您的建议作为答案发布以帮助其他社区成员。

您可以在永久虚拟机(而不是临时管道虚拟机)上手动运行它。执行时有提示:Proceed ([y]/n)?。 Azure 中的输出不会显示此提示。

要克服等待提示回复时超时的问题，您可以运行此命令conda install -y。它不要求确认。
