Azure 函数 Python 导入错误：libpython3.6m.so.1.0答案

【问题标题】：Azure Function Python Import Error : libpython3.6m.so.1.0Azure 函数 Python 导入错误：libpython3.6m.so.1.0

【问题描述】：

我有一个项目托管在 Microsoft Azure 上。它具有作为 Python 代码的 Azure 函数，它们最近停止工作（500 内部服务器错误）。该代码有我以前没有遇到过的错误，并且没有进行任何已知的更改（但这种可能性存在，因为其他团队的人可能在不告诉任何人的情况下更改了某处的配置）。

这是一些日志：

这是一个python文件的例子，错误在第9行触发，import pyodbc：

import simplejson as json
import azure.functions as func

from azure.keyvault import KeyVaultClient
from azure.common.credentials import ServicePrincipalCredentials
from datetime import datetime

import os
import pyodbc
import logging

# And then code

在我看来，服务器在访问某些 Python 资源或依赖项时遇到了困难，这与 libpython3.6 有关，但目前我不确定如何在 Azure 门户上解决问题。

【解决方案1】：

我们周五遇到了完全相同的问题。对我们有用的是用 pypyodbc 替换 pyodbc。我们这样做是为了不必在代码中更改它：

import pypyodbc as pyodbc

此外，我们升级了 Azure Functions 以使用 Python 3.7（可能很快会更新到 3.9）。从 2022 年 9 月 30 日起，Azure 将不再支持 Python 3.6：https://azure.microsoft.com/en-us/updates/azure-functions-support-for-python-36-is-ending-on-30-september-2022/
