Python 脚本中的 Azure 函数 ModuleNotFoundError

问题描述

我尝试在 Azure Function 中运行以下脚本:初始化.py

I have the following script which I am trying to run in Azure Function: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
"
                 f"Name: {myblob.name}
"
                 f"Blob Size: {myblob.length} bytes")

这里是function.json:

Here is the 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:

It was working fine when I imported only azure.functions and logging. I am getting this error only while trying to run the code in Azure Function.I am getting the following error for pandas or any other library for that matter:

Result: Failure

推荐答案

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.

You need to include a requirements.txt file with your code which lists all the python dependencies of your function.

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

requirements.txt: Contains the list of packages the system installs when publishing to Azure.
