【问题描述】：
根据AirFlow Offical documentation，我尝试了以下方法
# airflow needs a home, ~/airflow is the default,
# but you can lay foundation somewhere else if you prefer
# (optional)
export AIRFLOW_HOME=~/airflow
# install from pypi using pip
pip install apache-airflow
# initialize the database
airflow initdb
# start the web server, default port is 8080
airflow webserver -p 8080
但面对

@tobi6 感谢您的关注，在我发布此问题后，我尝试 pip uninstall apache-airflow ，尝试安装 pip install airflow ，一切正常。 （气流在气流的 1.8 版中），我们可以得出结论，它不取决于我的环境，而是取决于 apache-airflow 上的包，仅供参考，我的 ptyhon 版本是 3.6，我没有 anaconda，并且没有错误正在安装中。
