使用python3

Question

我試圖用slate模塊來提取PDF文件中的文本提取PDF文本，如本

$sudo pip install https://codeload.github.com/timClicks/slate/zip/master

    Uninstalling slate-0.3: 
     Successfully uninstalled slate-0.3 
    Running setup.py install for slate ... done 
Successfully installed slate-0.5.2 

，我想：

#!/usr/bin/python3 
import slate 

with open('/var/tmp/PhysRevB.93.014203.pdf') as fp: 
    doc = slate.PDF(fp) 
print(len(doc)) 
print(doc[0]) 

這是給我的錯誤：

$python3 tstslt.py 
Traceback (most recent call last): 
    File "tstslt.py", line 2, in <module> 
    import slate 
    File "/usr/lib/python3.5/site-packages/slate/__init__.py", line 66, in <module> 
    from .classes import PDF 
    File "/usr/lib/python3.5/site-packages/slate/classes.py", line 25, in <module> 
    import utils 
ImportError: No module named 'utils' 

我可以使用PyPDF2來提取文本，但看看是否s晚點比較好。

根據this issue一個平板的依賴條件的（pdfminer）不支持Python3

(...)

The "pdfminer" that is required does not work because it is currently incompatible with python 3.5.

It says so on their readme:

https://github.com/euske/pdfminer

"Install Python 2.6 or newer. (Python 3 is not supported.)"
