Python - pip安装pyublas：无法构建鸡蛋

Question

我在通过pip在Ubuntu 14.04上安装PyUblas时遇到问题。 我正在使用Python 2.7.6。

这里去日志：

有没有人有问题可以在这里有什么想法？ 在此先感谢。

我已经间歇性地遇到了这个问题。这是一个（完全hacky）修复程序，对我来说很有用。首先，下载PyUblas来源：

pip install pyublas -d . 
tar xvfz PyUblas-2013.1.tar.gz 
cd PyUblas-2013.1/ 

然后编辑aksetup_helper.py，并注释掉导致它使用的分发自己的定制版本的台词：

# dealings with ez_setup ------------------------------------------------------ 
# COMMENT OUT THE NEXT TWO LINES 
# import distribute_setup 
# distribute_setup.use_setuptools() 

import setuptools 
from setuptools import Extension 

然后最后只是做一个手动安装：

python setup.py install 

您的里程可能会有所不同。 :-)

编辑：而不是手动编辑文件，您也可以直接删除它试图导入的distribute_setup模块：echo "def use_setuptools(): pass" > distribute_setup.py。如果您想要编写流程脚本，这可能会更容易一些。
