我正在尝试使用内联编辑器重新部署以前运行的Python云功能。如果未更改source或requirements.txt，则部署将失败，并显示以下错误消息：

Deployment failure:
Function failed on loading user code. Error message: Error: cannot communicate with function.

功能日志提供以下详细信息：

 }
 severity: "ERROR"

这开始于上周五，一直持续到今天。我还尝试了使用gcloud函数deploy进行本地部署，并在其中收到类似的错误消息：

ERROR: (gcloud.functions.deploy) OperationError: code=3,message=Function failed on loading user code. Error message: Error: cannot communicate with function.

在解决此问题的后续步骤中，我将提供一些指导。

---更新---

根据达斯汀（Dustin）的建议，提供了源文件和需求文件，我研究了是否可以用最少的代码来重新创建问题。

main.py

import base64
import mysql.connector as db
from google.cloud import storage

def hello_pubsub(event,context):
    pubsub_message = base64.b64decode(event['data']).decode('utf-8')
    print(pubsub_message)

requirements.txt

google-cloud-storage==1.21.0
mysql-connector-python==8.0.18

事实证明google-cloud-storage的版本不兼容。更改为mysql-connector-phthon

因此问题已解决。
