Question

问候语，

我在https://docs.docker.com/compose/django/使用我的Docker环境在CentOS VM和Ubuntu VM中跟踪了docker撰写quickstart示例。该示例适用于CentOS，但不适用于Ubuntu。失败发生在

RUN pip install -r requirements.txt

错误是

你能不能帮助我解决这个问题，并理解为什么会在Ubuntu中发生这种情况，而不是在CentOS中呢？

...谢谢

Answer 1

事实证明我的/etc/resolv.conf指向了错误的名称服务器。我仍然需要调查为什么会这样。如果手动输入正确的DNS，则docker容器具有网络。

Answer 2

运行pip搜索并确保您所寻找的内容。从错误看起来它实际上找不到它。

Docker文档往往在主站点上过时。
