python - Docker 撰写脚本提示 python 模块导入

Question

Docker 脚本 docker-compose --version 现在抛出一个奇怪的错误，并提示缺少 python 模块 ordered_dict。不知道为什么会这样，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，后来使用 pip 安装了 awscli。

下面是我在运行 docker-compose --version

时得到的堆栈跟踪

通过安装 urllib3 版本 1.22 并通过在 shell 中执行以下命令卸载以前的 urllib3 版本

pip uninstall urllib3
pip install urllib3==1.22
