airflow 官网地址
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
将 /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。
