python - ImportError : No module named api_core. 异常

Question

我想为我的项目运行一个 google.cloud.storage 依赖项，所以我尝试安装这个依赖项

sudo pip install --upgrade google-api-python-client

运行上面的命令，我们在 apache airflow dist-packages 目录 ex:- /usr/local/python2.7/dist-packages/

当我使用以下代码将库导入我的项目时。

from airflow.contrib.operators.mysql_to_gcs import MySqlToGoogleCloudStorageOperator

在 Python 上运行项目，我收到错误 ImportError: No module named api_core.exceptions

这是痕迹

#python mysql_to_gcs.py

代替 --upgrade google-api-python-client 只需使用
重新安装 api-corepip 安装 dialogflow

升级有一些不更新 api-core 的奇怪问题。
