TypeError: int() 收到意外关键字参数 'base'，在 ironpython 的 pyPdf-1.15 中出错

Question

我成功安装了pyPDF2，输入的代码是pyPdf-1.15，在终端打开后输入这些代码

import os
from PyPDF2 import PdfFileReader
path = "F:/Download"
inputFileName = os.path.join(path, "RealPython.pdf")
inputFile = PdfFileReader(open(inputFileName, "rb"))

然后出现了这个

Traceback (most recent call last):
  File "<string>", line 1, in <module>

  File "C:\Program Files (x86)\IronPython 2.7\lib\site-packages\PyPDF2\pdf.py", line 797, in __init__
    self.read(stream)

    xrefstream = readObject(stream, self)

    return DictionaryObject.readFromStream(stream, pdf)

    arr.append(readObject(stream, pdf))

  File "C:\Program Files (x86)\IronPython 2.7\lib\site-packages\PyPDF2\generic.py", line 73, in readObject
    return readHexStringFromStream(stream)

  File "C:\Program Files (x86)\IronPython 2.7\lib\site-packages\PyPDF2\generic.py", line 302, in readHexStringFromStream
    txt += chr(int(x, base=16))


TypeError: int() got an unexpected keyword argument 'base'

我不知道我哪里做错了，有人能帮帮我吗？

错误信息：int() 收到了一个意外的关键字参数 'base'。这很可能和 IronPython 中 int 函数的实现有关。你可以尝试编辑 PyPDF2 包中的这个文件：C:\Program Files (x86)\IronPython 2.7\lib\site-packages\PyPDF2\generic.py（在第 302 行，函数名是 readHexStringFromStream）。把 16 作为第二个位置参数传给 int 函数：

#txt += chr(int(x, base=16))
txt += chr(int(x, 16))
