使用python setup.py时安装scikits.audiolab时出错egg_info

我正在尝试使用pip工具安装scikits.audiolab。 Pip似乎在scikits.audiolab源目录中运行命令python setup.py egg_info。当这样的时候，我得到这个错误：使用python setup.py时安装scikits.audiolab时出错egg_info

Andrews-MacBook-Pro-2:scikits.audiolab-0.11.0 andrewhannigan$ pip install scikits.audiolab 
Collecting scikits.audiolab 
    Using cached scikits.audiolab-0.11.0.tar.gz 
    Complete output from command python setup.py egg_info:

     from numpy.distutils.core import setup 
    ImportError: No module named numpy.distutils.core

问题显然是它无法导入numpy.distutils.core。纵观setup.py脚本，这种进口发生早期（在片段的下方底部）：

import os 
import sys 

# The following is more or less random copy/paste from numpy.distutils ... 
import setuptools 

from distutils.errors import DistutilsError 
from numpy.distutils.core import setup

奇怪的是，如果我只是通过python setup.py运行setup.py脚本的上述片段，我没有得到导入错误。 egg_info命令行参数如何影响setup.py的运行方式，以及为什么突然使python无法从numpy.distutils.core导入？

似乎不太可能，它是egg_info命令，而是点子正在改变以某种方式对环境.. 。点子使用正确的环境吗？你可以用pip -V –

来检查，或许这与你的问题有关：https://github.com/scipy/scipy/blob/v0.13.0b1/setup.py#L203 – denfromufa

如果numpy是这样安装的，那么它可能会工作：pip安装numpy - 用户 – denfromufa

scikits.audiolab的setup.py文件存在问题。看看https://github.com/cournape/audiolab/blob/master/setup.py：

import os 

# The following is more or less random copy/paste from numpy.distutils ... 
import setuptools 

from numpy.distutils.core import setup

它做的第一件事情是从numpy进口。如果未安装numpy，则可以确保这会导致您分享的导入错误失败。

我怀疑你的失败的安装尝试和你的成功安装之间，你用pip install numpy手动安装numpy。 egg_info不太可能与它有任何关系。

下面是如何解决这个问题，从拍摄的示范scipy项目的setup.py：

def setup_package(): 
    ... 
    build_requires = [] 
    try: 
     import numpy 
    except: 
     build_requires = ['numpy'] 

    metadata = dict(
     ... 
     setup_requires = build_requires, 
     install_requires = build_requires, 
    )
