pdfminer - 安装 PDFMiner for Python2.7 时出现错误

Question

我按照这里的说明操作:file:///home/bioinfo/Descargas/pdfminer3k-1.3.0/docs/index.html

下载 pdfminer3k-1.3.0 后我做了:

python setup.py install

但是当我这样做的时候

pdf2txt.py samples/simple1.pdf

而且它不读取pdf，路径没问题。它给我返回错误:

有什么解决办法吗？

最新代码(版本20140328)使用unichr()。试试这个:

pip install pdfminer==20140328

或从https://pypi.python.org/pypi/pdfminer/20140328下载.
