python-3.x - 如何修复 - TypeError：int() 参数必须是字符串、类似字节的对象或数字，而不是“PSKeyword”？

问题描述

我正在尝试使用 pdfminer 从 pdf 文件中提取文本，但我遇到了这个问题，但仅限于某些文件。该代码在某些 pdf 上运行良好，但会为其他人返回此错误消息。这是我的代码（我从这个论坛的其他线程复制过来的）：

import io
from pdfminer.converter import TextConverter
from pdfminer.pdfinterp import PDFPageInterpreter
from pdfminer.pdfinterp import PDFResourceManager
from pdfminer.pdfpage import PDFPage
def extract_text_from_pdf(pdf_path):
    resource_manager = PDFResourceManager()
    fake_file_handle = io.StringIO()
    converter = TextConverter(resource_manager, fake_file_handle)
    page_interpreter = PDFPageInterpreter(resource_manager, converter)

    with open(pdf_path, 'rb') as fh:
        for page in PDFPage.get_pages(fh, 
                                      caching=True,
                                      check_extractable=True):
            page_interpreter.process_page(page)
        
        text = fake_file_handle.getvalue()

    # close open handles
    converter.close()
    fake_file_handle.close()

    if text:
        return text

if __name__ == '__main__':
    print(extract_text_from_pdf('test.pdf'))*

这是我得到的错误：

Traceback (most recent call last):
  File "pdf.py", line 28, in <module>
    print(extract_text_from_pdf('test.pdf'))
  File "pdf.py", line 13, in extract_text_from_pdf

  File "C:\AppData\Local\Programs\Python\Python38-32\lib\site-packages\pdfminer\pdfpage.py", line 129, in get_pages
    doc = PDFDocument(parser, password=password, caching=caching)
  File "C:\AppData\Local\Programs\Python\Python38-32\lib\site-packages\pdfminer\pdfdocument.py", line 566, in __init__

  File "C:\AppData\Local\Programs\Python\Python38-32\lib\site-packages\pdfminer\pdfparser.py", line 79, in do_keyword
(objid, genno) = (int(objid), int(genno))
TypeError: int() argument must be a string, a bytes-like object or a number, not 'PSKeyword'

我一直在尝试寻找解决此问题的方法，但尚未成功。感谢帮助！多谢你们。
