由于cython依赖，无法在dind 18.09.6-dind上使用pip安装awscli

Question

我昨天看到了一个奇怪的问题，当使用容器docker:18.09.6-dind运行一个简单的jenkins构建时，当尝试使用pip安装awscli时，构建会失败。以下是示例代码：

​

apk add curl
apk add py-pip
pip install --user awscli

​

错误是:-

​

它一直运行良好，直到昨天，现在也工作得很好，在相同的dind操作系统。我不知道为什么就在昨天它还试图设置依赖cython。我看到一个新版本的cython昨天发布了https://pypi.org/search/?q=cython，不确定是否发挥了任何作用，我不是那么熟悉的pip工程，当它试图安装的东西，所以想知道为什么它突然寻找cython，而它的相同的pip版本18.1在那个dind操作系统上，并试图获取最新的awscli，这碰巧是昨天1.19.51发布，根据https://github.com/aws/aws-cli/releases也昨天，同样的事情都很好，在整个docker:18.06.1-ce-dind或其他dind版本。因此，特定于docker:18.09.6-dind以及pip 18.1和awscli 1.19.51的组合。请帮助我找出这里可能存在的问题。
