Docker编写脚本抱怨python模块imp

Question

Docker脚本docker-compose --version现在抛出了一个奇怪的错误，并抱怨缺少python模块ordered_dict。不知道为什么会发生这种情况，但以前它工作得很好。不确定它是否相关，但我为python安装了pip，随后使用pip安装了awscli。

下面是我在运行docker-compose --version时得到的堆栈跟踪

Answer 1

通过安装urllib3版本1.22和通过在shell中执行以下命令卸载以前的urllib3版本来完成此操作

pip uninstall urllib3
pip install urllib3==1.22

Answer 2

重新安装docker compose帮了我一把。您可以从/usr/local/bin中删除docker-compose文件，然后使用提供的here说明重新安装。
