Question

我正在尝试使用Azure App Service上的Python WebJob从blob存储读取/写入。 My App Service的requirements.txt文件包含azure-storage软件包名称：在App Service部署期间通过pip成功安装软件包。但是，当我在WebJob的run.py文件中包含以下内容时：

import sys
sys.path.append('D:\\home\\site\\wwwroot\\env\\Lib\\site-packages')
from azure.storage.blob import BlockBlobService

...我在运行时收到以下错误消息：

FWIW，使用相同的方法正确加载了其他几个包。任何人都可以建议一种方法来让Azure Azure WebJobs中的azure-storage包工作吗？

Answer 1

看起来缺少六个模块。此问题也通过以下线程进行跟踪：https://github.com/Azure/azure-storage-python/issues/22。您可以通过将六个模块添加到requirements.txt或通过pip install six手动安装六个模块来解决问题。

无法通过Python WebJob中的azure-storage包访问blob存储
