无法导入airflow.providers的气流

Question

我想进口气流谷歌供应商。所以我安装了它。

pip3 install apache-airflow-backport-providers-google

我能够看到包目录下的所有钩子和所有东西。

/usr/local/lib/python3.7/dist-packages/airflow/providers/google/cloud/transfer

但是当我运行import命令时，它失败了。

from airflow.providers.google.cloud.transfers.sql_to_gcs import BaseSQLToGCSOperator


Error:
Traceback (most recent call last):
  File "test1.py", line 8, in <module>
    from custom.custom_PostgresToGCSOperator import custom_PostgresToGCSOperator
  File "/root/airflow/dags/custom/custom_PostgresToGCSOperator.py", line 8, in <module>
    from airflow.providers.google.cloud.transfers.sql_to_gcs import BaseSQLToGCSOperator
ModuleNotFoundError: No module named 'airflow.providers'

升级到2.0.0a1时，我也遇到了同样的问题，我所做的是：

package

• Download升级版本：
• wget https://dist.apache.org/repos/dist/dev/airflow/2.0.0a1/apache-airflow-2.0.0a1-bin.tar.gz

安装apache-airflow-2.0.0a1-bin.tar.gz

• airflow db upgrade

• airflow调度程序-D；气流网络服务器-D
