我第一次尝试使用airflow，并尝试将其连接到本地sqlite数据库。但我似乎不知道该怎么做。
我读了airflow的文件 executor 至 LocalExecutor 并设置我的 sql_alchemy_conn 至 sqlite:////home/myName/Programs/sqlite3/DatabaseName.db 但当它抛出一个

Traceback (most recent call last):
  File "/usr/local/bin/airflow", line 21, in <module>
    from airflow import configuration
  File "/usr/local/lib/python2.7/dist-packages/airflow/__init__.py", line 35, in <module>
    from airflow import configuration as conf
  File "/usr/local/lib/python2.7/dist-packages/airflow/configuration.py", line 520, in <module>
    conf.read(AIRFLOW_CONFIG)
  File "/usr/local/lib/python2.7/dist-packages/airflow/configuration.py", line 283, in read
    self._validate()
  File "/usr/local/lib/python2.7/dist-packages/airflow/configuration.py", line 169, in _validate
    self.get('core', 'executor')))
airflow.exceptions.AirflowConfigException: error: cannot use sqlite with the LocalExecutor

尝试运行时出错 airflow initdb . 我试着到处搜索，试着VipulSharma在这里找到的解决方案，并设置我的 sql_alchemy_conn 至 mysql://:@localhost:3306/ 但当它抛出一个

sqlalchemy.exc.OperationalError: (_mysql_exceptions.OperationalError) (1045, "Access denied for user 'myName'@'localhost' (using password: NO)")

错误。我知道答案应该很简单，但我真的不明白怎么做，所以我希望你能指导我做什么/读什么。
