Python pdf2image 在 docker 容器中失败

我有一个在 docker 容器中运行的Python项目，但我无法让convert_from_path运行(从pdf2image库).它在我的Windows PC上本地运行，但不能在基于Linux的坞站容器中运行.

我每次得到的误差是Unable to get page count. Is poppler installed and in PATH?

我的代码的相关部分如下所示

from pdf2image import convert_from_path
import os
from sys import exit

def my_function(file_source_path):
    try:
        pages = convert_from_path(file_source_path, 600, poppler_path=os.environ.get('POPPLER_PATH'))
    except Exception as e:
        print('Fail 1')
        print(e)
    try:
        pages = convert_from_path(file_source_path, 600)
    except Exception as e:
        print('Fail 2')
        print(e)
    try:
        pages = convert_from_path(file_source_path, 600, poppler_path=r'\usr\local\bin')
    except Exception as e:
        print('Fail 3')
        print(e)
        print(os.environ)
        exit('Exiting script')

在try 1中，我try 引用保存在Windows上的原始文件.基本上，路径是指'/code/poppler'，这是指

[snippet from docker-compose.yml]
- type: bind
  source: "C:/Program Files/poppler-0.68.0/bin"
  target: /code/poppler

在try 2中，我只是try 将路径留空.在try 3中，我try 了一些我发现在本地其他用户处起作用的东西.

我的文档文件的相关部分如下所示

FROM python:3.10

WORKDIR /code

# install poppler
RUN apt-get update
RUN apt-get install poppler-utils -y

COPY ./requirements.txt ./
RUN pip install --upgrade pip
RUN pip install --no-cache-dir -r requirements.txt
