Python 脚本中的 Azure 函数 ModuleNotFoundError

Question

我尝试在 Azure Function 中运行以下脚本： 初始化.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": ""
        }
    ]
}

当我只导入 azure.functions 和日志时，它工作正常。我仅在尝试在 Azure Function 中运行代码时收到此错误。 对于 pandas 或任何其他库，我收到以下错误：

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，其中列出了您的函数的所有 python 依赖项。

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