我正在使用mint Linux mint 13 maya（Linux 3.2.0-23-generic x86-64）
我试图安装scikits.audiolab来执行一些音频信号处理。我已经下载了所有先决条件，即（python dev python numpython setuptools libsndfile dev）。
我已将site.cfg设置为
[sndfile]
include_dirs = /usr/include/
library_dirs = /usr/lib/x86_64-linux-gnu/
我得到以下错误
SndfileInfo:
FOUND:
libraries = ['sndfile']
library_dirs = ['/usr/lib/x86_64-linux-gnu/']
include_dirs = ['/usr/include/']

如何使setup.py找到库。有什么我遗漏的吗？
我见过http://forum.ubuntu-fr.org/viewtopic.php?pid=3748397和scikits.audiolab on Ubuntu Oneiric - ImportError: No module named _sndfile
这真是太麻烦了
更新
在我的一台电脑中，完全卸载scikits audiolab和alsa，然后在重新安装alsa和scikits audiolab之前更新apt-get时，此错误被删除。
最佳答案
以下是我在Ubuntu上使用alsa音频后端的原因。
按照http://cournape.github.io/audiolab/installing.html#installation-from-sources中的说明，安装alsa头：
$ sudo apt-get install libasound2-dev
在源目录中，
/路径/scikits.audiolab-0.11.0/
或者，如果使用pip（source默认下载到/tmp）
/tmp/pip构建/scikits.audiolab
创建site.cfg文件，除了[sndfile]部分之外，还创建一个[alsa]部分：
[sndfile]
include_dirs = /usr/include
library_dirs = /usr/lib/x86_64-linux-gnu/
[alsa]
include_dirs = /usr/include/alsa
library_dirs = /usr/lib/x86_64-linux-gnu
使用locate或apt file list查找asoundlib.h（包含目录）和libasound.so（库目录）在系统中的位置。
好吧，在做了这些并试图重新安装之后，它仍然没有工作。我一直收到同样令人沮丧的信息：
SndfileInfo:
FOUND:
libraries = ['sndfile']
library_dirs = ['/usr/lib/x86_64-linux-gnu']
include_dirs = ['/usr/include']
AlsaInfo:
alsa not found
scikits/audiolab/soundio/setup.py:21: UserWarning: Alsa not found - alsa backend not build
warnings.warn("Alsa not found - alsa backend not build")
所以，我不得不用这个方法。打开文件/path to/scikits.audiolab-0.11.0/scikits/audiolab/soundio/setup.py并替换
14 alsa_info = info_factory('alsa', ['asound'], ['alsa/asoundlib.h'],
15 classname='AlsaInfo')()
具有
alsa_info = info_factory('alsa', ['asound'], ['asoundlib.h'],
classname='AlsaInfo')()
如果这对更多人有效，我们可以要求David Cournapeau（scikits.audiolab author）制作此修补程序。
