airflow 官网地址

http://airflow.apache.org/

系统环境:

  • CentOS release 6.5 (Final)
  • python 2.7.13
  • pip 9.0.1

问题浮现

使用官网 Quick Start 中的方式, 在 root 用户下安装 airflow

export AIRFLOW_HOME=~/airflow
pip install airflow
airflow initdb

以上命令都可以正常执行 当启动 airflow 时

/usr/local/python-2.7.13/bin/airflow webserver

报如下错误

解决方案

/usr/local/python-2.7.13/bin/ 配置到环境变量中

export PATH=$PATH:/usr/local/python-2.7.13/bin/

再次启动 ariflow , 问题解决。
