尝试使用 aws cli 从 AWS S3 复制文件时遇到类似问题。 运行 pip install python-dateutil 将 python-dateutil 更新为 2.8.1，现在运行良好。
python -m pip install --upgrade python-dateutil
升级python-dateutil解决了我的问题。在我的机器上，2.5.3 到 2.8.1。
略读源码，发现在2.7.0中添加了UTC变量。所以，我认为任何版本 >= 2.7.0 都可以解决问题。
#: Convenience constant providing a :class:`tzutc()` instance

#: .. versionadded:: 2.7.0
UTC = tzutc()
尝试指定 python-dateutil 版本并将其安装在有错误的包之前，在您的情况下为 zappa
示例：
pip install python-dateutil==2.8.1 zappa
我的情况是我收到错误的包裹是 freezegun，所以我 运行
pip install python-dateutil==2.8.1 freezegun==0.3.15
成功了
我在尝试 运行 eb deploy AWS Elastic Beanstalk 时遇到了这个问题。
对我有用的是： sudo pip3 install python-dateutil --upgrade
（注意：运行在没有 sudo 的情况下执行此操作无法解决问题）
作为参考，这是我在此之前遇到的错误：
