python PyPDF2 AttributeError: 'WindowsPath' 对象没有属性 'seek'

如何解决python PyPDF2 AttributeError: 'WindowsPath' 对象没有属性 'seek'

我在一本书中做一个python挑战，然后我遇到了这个错误。我已经尝试过应对此挑战的解决方案，但没有奏效，而且针对此挑战的互联网解决方案似乎也不起作用。有谁能帮帮我吗？

from PyPDF2 import PdfFileReader,PdfFileWriter
from pathlib import Path
class PdfFileSplitter:
    """This class can be used to split a pdf into two new PDFs"""

def __init__(self,file):
    self.file = file
    self.writer1 = None
    self.writer2 = None

def split(self,breakpoint):
    self.writer1 = PdfFileWriter()
    self.writer2 = PdfFileWriter()
    for page in PdfFileReader(self.file).pages[:breakpoint]:
        self.writer1.addPage(page)

    for page in PdfFileReader(self.file).pages[breakpoint:]:
        self.writer2.addPage(page)
    pass
def writer(self,filename):
    with Path(f"{filename}_1.pdf").open(mode="wb") as output1:
        self.writer1.write(output1)

    with Path(f"{filename}_2.pdf").open(mode="wb") as output2:
        self.writer2.write(output2)

pass

pdf_path = (
 Path.home() /
 "python-basics-exercises" /
 "ch14-interact-with-pdf-files" /
 "practice_files" /
 "Pride_and_Prejudice.pdf"
)

pdf_splitter = PdfFileSplitter(pdf_path)
pdf_splitter.split(breakpoint=150)
pdf_splitter.writer("pride_pdf")
