Google bigquery 使用气流从Google存储导出到BQ时出错

我正在尝试从Google云存储导出一个文件并将其加载到BigQuery。 执行此操作时，我收到以下错误：

Traceback (most recent call last):
  File "/usr/local/lib/python2.7/site-packages/airflow/models.py", line 285, in process_file

    from airflow.contrib.operators.mysql_to_gcs import MySqlToGoogleCloudStorageOperatorfrom
ImportError: cannot import name MySqlToGoogleCloudStorageOperatorfrom
Done.

我试图添加/更改DAG的参数，但没有成功。任何见解都会有帮助

此错误与GBQ无关，请参阅错误消息：

airflow.exceptions.AirflowException: dag_id could not be found: test. Either the dag did not exist or it failed to parse.

首先检查是否可以将DAG与

airflow list_dags

如果这不起作用，则说明DAG中存在错误。此外，错误原因已存在于输出中：

ImportError: cannot import name MySqlToGoogleCloudStorageOperatorfrom

似乎是一个拼写错误，应该是

MySqlToGoogleCloudStorageOperator

在您的导入中。
