Python 中的 Slate 在山麓上跌跌撞撞

Question

尝试将PDF解析为文本，并一直在尝试从Slate入手。

但是，只要按照随处发布的基本示例，我得到以下结果：

>>> import slate
>>> with open('pytest.PDF') as fp:
...     doc = slate.PDF(fp)
... 
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/slate/slate.py", line 52, in __init__
self.append(self.interpreter.process_page(page))
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/slate/slate.py", line 36, in process_page
self.device.outfp.buf = ''
AttributeError: 'cStringIO.StringO' object has no attribute 'buf'

有什么想法吗？

Answer 1

可以通过将发生错误的第 36 行更改为：

来修复此问题

self.device.outfp.truncate(0)
