已安装Poppler:为什么在python3上使用pdf2image会出现错误?

问题描述

我在macOS 10.14.6上使用python 3.7.4 ，并且尝试使用 pdf2image 将pdf文件转换为图像.所以我用 Homebrew 安装了 poppler .尝试转换PDF时收到错误消息.

I am using python 3.7.4 on a macOS 10.14.6 and I am trying to use pdf2image to convert a pdf file into an image. So I have installed poppler with Homebrew. I get an error message when I try to convert the PDF.

Traceback (most recent call last):   File "/usr/local/lib/python3.7/site-packages/pdf2image/pdf2image.py", line 240, in _page_count
    proc = Popen(command, env=env, stdout=PIPE, stderr=PIPE)   File "/usr/local/Cellar/python/3.7.4/Frameworks/Python.framework/Versions/3.7/lib/python3.7/subprocess.py", line 775, in __init__
    restore_signals, start_new_session)   File "/usr/local/Cellar/python/3.7.4/Frameworks/Python.framework/Versions/3.7/lib/python3.7/subprocess.py", line 1522, in _execute_child
    raise child_exception_type(errno_num, err_msg, err_filename) FileNotFoundError: [Errno 2] No such file or directory: 'pdfinfo': 'pdfinfo'

我使用以下代码:

from pdf2image import convert_from_path, convert_from_bytes
from pdf2image.exceptions import (
    PDFInfoNotInstalledError,
    PDFPageCountError,
    PDFSyntaxError
)

images = convert_from_path('test.pdf')

在处理上述异常期间，发生了另一个异常:

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/Users/michelebutturini/Desktop/Segmentation.py", line 16, in <module>
    images = convert_from_path('test.pdf')
  File "/usr/local/lib/python3.7/site-packages/pdf2image/pdf2image.py", line 54, in convert_from_path
    page_count = _page_count(pdf_path, userpw, poppler_path=poppler_path)
  File "/usr/local/lib/python3.7/site-packages/pdf2image/pdf2image.py", line 244, in _page_count
    raise PDFInfoNotInstalledError('Unable to get page count. Is poppler installed and in PATH?')
pdf2image.exceptions.PDFInfoNotInstalledError: Unable to get page count. Is poppler installed and in PATH?
