无法使用 Camelot 读取 PDF 文件

问题描述

我正在尝试在烧瓶上使用 camelot 阅读 PDF，但出现此错误 -

"message": "Traceback (most recent call last):
  File "/home/uche/.local/share/virtualenvs/my_project-mgeNnedW/lib/python3.6/site-packages/werkzeug/datastructures.py",line 3089,in __getattr__
    return getattr(self.stream,name)
AttributeError: 'SpooledTemporaryFile' object has no attribute 'lower'

During handling of the above exception,another exception occurred:

Traceback (most recent call last):
  File "/home/user/my_project/statement.py",line 65,in read_statement
    tables = camelot.read_pdf(file,flavor='stream')
  File "/home/uche/.local/share/virtualenvs/bank_statement-mgeNnedW/lib/python3.6/site-packages/camelot/io.py",line 111,in read_pdf
    p = PDFHandler(filepath,pages=pages,password=password)
  File "/home/user/.local/share/virtualenvs/my_project-mgeNnedW/lib/python3.6/site-packages/camelot/handlers.py",line 41,in __init__
    if not filepath.lower().endswith(".pdf"):
  File "/home/uche/.local/share/virtualenvs/my_project-mgeNnedW/lib/python3.6/site-packages/werkzeug/datastructures.py",line 3095,in __getattr__
    return getattr(self.stream._file,name)
AttributeError: '_io.BytesIO' object has no attribute 'lower'

这是我正在做的：

 tables = camelot.read_pdf('file.pdf',flavor='stream',pages='all',row_tol=10)

请注意，如果我尝试通过 python shell 读取此文件，它会起作用。

我该如何解决这个问题？
