b页后出现Reportlab错误

Question

我正在设计一个两页纸的双面打印表格。添加pagebreak后，我得到以下错误：

    File "f:\Dropbox\pms\pms_reports.py", line 450, in <module>
  a = Key_card1()
File "f:\Dropbox\pms\pms_reports.py", line 441, in __init__
  doc.build(elements)
File "c:\Python34\Lib\site-packages\reportlab\platypus\doctemplate.py", line 1171, in build
  BaseDocTemplate.build(self,flowables, canvasmaker=canvasmaker)
File "c:\Python34\Lib\site-packages\reportlab\platypus\doctemplate.py", line 927, in build
  self.handle_flowable(flowables)
File "c:\Python34\Lib\site-packages\reportlab\platypus\doctemplate.py", line 775, in handle_flowable
  self.handle_keepWithNext(flowables)
File "c:\Python34\Lib\site-packages\reportlab\platypus\doctemplate.py", line 742, in handle_keepWithNext
  while i<n and flowables[i].getKeepWithNext(): i += 1

builtins.TypeError: getKeepWithNext() missing 1 required positional argument: 'self'

这是我的代码：

^{pr2}$

我试图修改Reportlab模块，但没有成功。有人有什么想法吗？在

我已经试着去理解这个错误，我想这里面有问题 doc = SimpleDocTemplate("key_card.pdf", pagesize=A4)。问题可能是参数“key”_卡片.pdf". 我不确定

编辑：也许，BaseDocTemplate.build(self,flowables, canvasmaker=canvasmaker)问题是关于连接到文档生成（元素）

解决方案->；元素.append（PageBreak）应该是元素.append（PageBreak（））
