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

Question

我有一个项目托管在 Microsoft Azure 上。 它具有 Azure 代码为 Python 的函数，它们最近停止工作（500 内部服务器错误）。 代码有我以前没有的错误，并且没有进行任何已知的更改（但存在这种可能性，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 python 文件的示例，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，它与libpython3.6有关，但此时我不确定在 Azure 门户上如何解决问题。

Answer 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 函数以使用 Python 3.7（可能很快会更新到 3.9）。 Azure will not be supporting Python 3.6 as of September 30, 2022 anyways: https://azure.microsoft.com/en-us/updates/azure-functions-support-for-python-36-is-ending-on-30 -2022 年 9 月/

Answer 2

上周四我也面临同样的问题。 但是，我们已经尝试了互联网上可用的大多数解决方案，但没有一个对我们有帮助。

最后，我们刚刚将 Azure Function 运行时 Python 3.6 更新到 3.7 和 Boommm.. 它工作。

Moreover, we have also noticed that when we tried to create new Azure Function App based on Linux, that time were not able to select Python3.6 as runtime stack.

再次感谢各位。
