为 Python2.7 安装 PDFMiner 时观察到错误

Question

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

下载pdfminer3k-1.3.0后我做了：

python setup.py 安装

但是当我这样做时

pdf2txt.py 样本/simple1.pdf

它不读取pdf，路径没问题。它给了我错误：

>

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。
