Python Urllib ContextualVersionConflict

Question

直到10月20日，一切都很好。10月21日，它失败了，出现以下消息。这里有人能帮上忙吗

Answer 1

2020年10月19日，AWS发布了新的botocore版本1.19.0。到目前为止，1.19.0、1.19.1、1.19.2版本与elasticsearch-curator - 5.8.1版本不兼容。我安装了旧版本的elasticsearch-curator -version5.6.0，也遇到了同样的问题和临时修复的问题。我相信AWS将很快发布与elasticsearch-curator -version5.8.1兼容的botocore版本。
