气流启动由于gunicorn而失败

Question

Traceback (most recent call last):
  File "./python_runtime/bin/airflow", line 15, in <module>
    args.func(args)
  File "/home/admin/airflow/python_runtime/lib/python2.7/site-packages/airflow/bin/cli.py", line 423, in webserver
    'gunicorn', run_args
  File "/home/admin/airflow/python_runtime/lib/python2.7/os.py", line 346, in execvp
    _execvpe(file, args)
  File "/home/admin/airflow/python_runtime/lib/python2.7/os.py", line 385, in _execvpe
    func(fullname, *argrest)
OSError: [Errno 2] No such file or directory

我发现这个错误是由于没有gunicorn可用,所以我在os.py中打印所有路径:

/home/admin/airflow/python_runtime/bin/gunicorn
/home/admin/python2.7.2/bin/gunicorn
/home/admin/tools/local/bin/gunicorn
/home/admin/tools/bin/gunicorn
/home/admin/tools/opsdb/gunicorn
/home/admin/odps_tools/dship/gunicorn
/home/admin/php/bin/gunicorn
/home/admin/cmake/bin/gunicorn
/home/admin/jdk1.6.0_24/bin/gunicorn
/home/admin/tools/bin/gunicorn
/usr/kerberos/bin/gunicorn
/usr/local/sbin/gunicorn
/usr/sbin/gunicorn
/sbin/gunicorn
/usr/local/bin/gunicorn
/bin/gunicorn
/usr/bin/gunicorn
/usr/X11R6/bin/gunicorn

而gunicorn存在于这条道路上

/home/admin/airflow/python_runtime/bin/gunicorn

我的环境出了什么问题？

Airflow 似乎期望在 PATH 中使用 gunicorn。对于我的 ubuntu 实例，这修复了它：

$ export PATH=$PATH:~/.local/bin $ airflow webserver
