Python 巴什多恩'；t运行bash文件

我刚开始使用apache airflow。我正在尝试从airflow运行test.sh文件，但无法运行

下面是我的代码，文件名是test.py

import os
from airflow import DAG
from airflow.operators.bash_operator import BashOperator
from datetime import datetime, timedelta


default_args = {
    'owner': 'airflow',
    'depends_on_past': False,
    'start_date': datetime(2015, 6, 1),
    'email': ['airflow@airflow.com'],
    'email_on_failure': False,
    'email_on_retry': False,
    'retries': 1,
    'retry_delay': timedelta(minutes=5),
    # 'queue': 'bash_queue',
    # 'pool': 'backfill',
    # 'priority_weight': 10,
    # 'end_date': datetime(2016, 1, 1),
}

dag = DAG('test', default_args=default_args)

# t1 and t2 are examples of tasks created by instantiating operators
t1 = BashOperator(
    task_id='print_date',
    bash_command='date',
    dag=dag)

create_command = "sh home/ubuntu/test/inst/scripts/test.sh"

if os.path.exists(create_command):
   t2 = BashOperator(
        task_id= 'cllTest',
        bash_command=create_command,
        dag=dag
   )
else:
    raise Exception("Cannot locate {}".format(create_command))

t2.set_upstream(t1)

当我运行python~/aiffort/dags/test.py时，它不会抛出任何错误

但是，当我运行airflow list_dag时，它会抛出以下错误：

[2017-02-15 20:20:02,741] {__init__.py:36} INFO - Using executor SequentialExecutor

我试着用它来回答，它不起作用

我在哪里犯错

尝试不使用“sh”，只需将命令设置为“home/ubuntu/test/inst/scripts/test.sh”

只使用脚本路径，不使用“sh”： create_command=“/home/ubuntu/test/inst/scripts/test.sh”

---

还要确保“airflow”用户具有执行“test.sh”脚本的权限

在.sh之后添加空格应该可以 这一点在《气流》一书中有所提及

t2 = BashOperator(
task_id='sleep',
bash_command="/home/batcher/test.sh", // This fails with `Jinja template not found` error
#bash_command="/home/batcher/test.sh ", // This works (has a space after)
dag=dag)
