Python脚本中的Azure Function ModuleNotFoundError

Question

我具有以下试图在Azure Function中运行的脚本：init。py

import logging
import azure.functions as func
import pandas as pd
import numpy as np
from datetime import datetime

def main(myblob: func.InputStream):
    logging.info(f"Python blob trigger function processed blob \n"
                 f"Name: {myblob.name}\n"
                 f"Blob Size: {myblob.length} bytes")

这里是function.json：

{
    "scriptFile": "__init__.py",
    "bindings": [
        {
            "name": "myblob",
            "type": "blobTrigger",
            "direction": "in",
            "path": "uwci-sftp-rb92351a6c-41fa-4b90-aa79-4e9974ca83f7/{name}",
            "connection": ""
        }
    ]
}

当我仅导入azure.functions和日志记录时，它工作正常。仅在尝试在Azure Function中运行代码时出现此错误。对于此问题，我对熊猫或任何其他图书馆出现以下错误：

Result: Failure
Exception: ModuleNotFoundError: No module named 'pandas'
Stack:   File "/azure-functions-host/workers/python/3.7/LINUX/X64/azure_functions_worker/dispatcher.py", line 242, in _handle__function_load_request

    import pandas as pd ```

Answer 1

您需要在代码中包含一个requirements.txt文件，其中列出了函数的所有python依赖项。

requirements.txt：包含发布到Azure时系统安装的软件包列表。
