我在两个 AWS EC2 实例上运行的集群环境中运行 Airflow。一份给主人，一份给工人。不过，工作节点在运行“$airflowworker”时会定期抛出此错误：

我该如何使用pip？
在生产环境中使用它也安全吗？
我有一个使用Airflow版本1.9的Airflow环境,该环境在Amazon EC2实例上运行.我需要升级到Airflow的最新版本1.10.我可以选择从1.9版升级或在新服务器上新安装1.10.气流版本1.10未在Pip上列出,所以我通过此命令从Git安装它,
pip-3.6 install git+git://github.com/apache/incubator-airflow.git@v1-10-stable
此命令成功安装Airflow版本1.10.您可以通过运行命令airflow version并查看输出来查看
