Python安装pyublas :无法构建Egg

Question

我在Ubuntu14.04上通过pip安装PyUblas有困难。我正在使用Python2.7.6。

原木开始了：

Traceback (most recent call last):

    _build_egg(egg, tarball, to_dir)
  File "distribute_setup.py", line 123, in _build_egg
    raise IOError('Could not build the egg.')
IOError: Could not build the egg.

有没有人知道这里会有什么问题？提前谢谢。

我间歇性地遇到了这个问题。这里有一个(完全无趣的)修复对我有效。首先，下载PyUblas源代码：

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自己的自定义分发版本的行：

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

import setuptools
from setuptools import Extension

最后，只需手动安装：

python setup.py install

你的里程可能会不同。:-)

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