Azure Python 函数中的导入模块错误 (Linux)

Question

我使用 VS Code 在我的 Windows 机器中创建了 Python 队列触发器。要安装模块，我创建了虚拟环境并 pip 安装了所有必需的模块。我在消费计划中将这个functionApp从VSCode部署到Linux os上的Azure。当我从 Azure 运行此函数时，它会引发导入模块错误，如果它没有获取模块，我不会。没有 Kudu 可用于安装模块。我已将所有模块版本放在 Requirement.txt 中。 需求.txt-

azure-common==1.1.25
azure-core==1.4.0
azure-functions==1.2.0
azure-nspkg==3.0.2
azure-storage==0.36.0
azure-storage-blob==12.3.0
azure-storage-common==2.1.0
certifi==2020.4.5.1
cffi==1.14.0
chardet==3.0.4
cryptography==2.9.2
idna==2.9
isodate==0.6.0
msrest==0.6.13
numpy==1.18.3
oauthlib==3.1.0
pandas==1.0.3
pip==19.2.3
pycparser==2.20
python-dateutil==2.8.1
pytz==2020.1
requests==2.23.0
requests-oauthlib==1.3.0
setuptools==41.2.0
six==1.14.0
urllib3==1.25.9
wheel==0.34.2

我的虚拟环境文件夹与所有功能处于同一级别，并且我使用的是 python 3.6。 代码截图 -

import os

import platform
import json
import requests
import datetime
import pandas as pd
import numpy as np
from datetime import timedelta
from pandas import json_normalize
from azure.storage.blob import BlockBlobService, AppendBlobService
import azure.functions as func


# read the queue message and write to stdout
def main(msg: func.QueueMessage):
    print ("ShiftAdmitPreprocessingWest - started")
    blobaccess = msg.get_json()

来自 Azure 的错误 -

你可以试试这个方法吗？

from azure.storage.blob.blockblobservice import BlockBlobService
