如何修复“在库'<None>'中找不到错误：符号'setMsgSeverity'：python：未定义符号：setMsgSeverity“天蓝色函数python”

Question

我在以azure函数运行的python脚本上导入ocrmypdf lib时遇到问题。

Function应用程序正在WestEurope地区的linux和B1 appserviceplan上运行。

import sys
import os
sys.path.append(os.path.abspath(os.path.join(os.path.dirname( __file__ ), 'a/Lib/site-packages')))
import logging
from invoice2data import extract_data
import json
import img2pdf
from ocrmypdf import leptonica
import ocrmypdf
import azure.functions as func
from azure.cosmosdb.table.tableservice import TableService
from azure.cosmosdb.table.models import Entity

我希望导入lib时不会出现错误，但实际上最终会出现以下错误：

Result: Failure
Exception: error: symbol 'setMsgSeverity' not found in library '<None>': python: undefined symbol: setMsgSeverity

任何建议都会被采纳：）
