BashOperator doen't run bash command apache airflow - airflow

Question

I was running the tutorial of airflow. The content in the tutorial.py is as follows:
"""
Code that goes along with the Airflow located at:
http://airflow.readthedocs.org/en/latest/tutorial.html
"""
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#example.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(
'tutorial', default_args=default_args, schedule_interval=timedelta(1))
# t1, t2 and t3 are examples of tasks created by instantiating operators
t1 = BashOperator(
task_id='print_date',
bash_command='date',
dag=dag)
t2 = BashOperator(
task_id='sleep',
bash_command='sleep 5',
retries=3,
dag=dag)
templated_command = """
{% for i in range(5) %}
echo "{{ ds }}"
echo "{{ macros.ds_add(ds, 7)}}"
echo "{{ params.my_param }}"
{% endfor %}
"""
t3 = BashOperator(
task_id='templated',
bash_command=templated_command,
params={'my_param': 'Parameter I passed in'},
dag=dag)
t2.set_upstream(t1)
t3.set_upstream(t1)
The tutorial.py is under ~/airflow/dags. By running airflow list_dags I can see the tutorial at the end of list.
However, when I run airflow test tutorial print_date 2018-09-04, it only prints:
[2018-09-04 22:14:43,096] {__init__.py:51} INFO - Using executor SequentialExecutor
[2018-09-04 22:14:43,199] {models.py:258} INFO - Filling up the DagBag from /Users/chenyuanfei/airflow/dags
And nothing else.
I'm using apche-airflow 1.10 on OSX.
How can I correctly run the script?

Answer 1

I'm doubting if it's because I have both airflow1.8 and apache-airflow1.10 on my mac.
I uninstalled both and reinstalled airflow1.8, and this time it works
