報錯如下：

Traceback (most recent call last):
  File "./pdf_merge.py", line 68, in <module>
    main(sys.argv[1], sys.argv[2])
  File "./pdf_merge.py", line 51, in main

    tx, ty], expand)
  File "/Users/root/Library/Python/2.7/lib/python/site-packages/PyPDF2/pdf.py", line 2328, in mergeTransformedPage
    PageObject._addTransformationMatrix(page2Content, page2.pdf, ctm), ctm, expand)

  File "/Users/root/Library/Python/2.7/lib/python/site-packages/PyPDF2/pdf.py", line 2189, in _contentStreamRename
    op = operands[i]
KeyError: 0

解決：

打開 /Users/root/Library/Python/2.7/lib/python/site-packages/PyPDF2/pdf.py
在文件開頭加上 import types
找到函數 _contentStreamRename
修改函數：

    def _contentStreamRename(stream, rename, pdf):
        if not rename:
            return stream
        stream = ContentStream(stream, pdf)
        for operands, operator in stream.operations:
            # for i in range(len(operands)):
            #     op = operands[i]
            #     if isinstance(op, NameObject):
            #         operands[i] = rename.get(op,op)
            if type(operands) == types.ListType:
                for i in range(len(operands)):
                    op = operands[i]
                    if isinstance(op, NameObject):
                        operands[i] = rename.get(op,op)
            elif type(operands) == types.DictType:
                for i in operands:
                    op = operands[i]
                    if isinstance(op, NameObject):
                        operands[i] = rename.get(op,op)
            else:
                raise KeyError("type of operands is %s" % type(operands))
        return stream
    _contentStreamRename = staticmethod(_contentStreamRename)
