我正在使用薄荷Linux Mint 13 maya（linux 3.2.0-23-generic x86-64）
我正在尝试安装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-numpy python-setuptools libsndfile-dev）。
我已将site.cfg设为
[sndfile]
include_dirs = /usr/include/
library_dirs = /usr/lib/x86_64-linux-gnu/
我收到以下错误
SndfileInfo:
FOUND:
libraries = ['sndfile']
library_dirs = ['/usr/lib/x86_64-linux-gnu/']
include_dirs = ['/usr/include/']
AlsaInfo:

如何让setup.py找到库。有什么我想念的吗？ 我看过http://forum.ubuntu-fr.org/viewtopic.php?pid=3748397和scikits.audiolab on Ubuntu Oneiric - ImportError: No module named _sndfile
这引起了很多挫折
更新
在我的一台PC中，在完全取消安装scikits-audiolab和alsa之后删除了这个错误，然后在重新安装alsa和scikits-audiolab之前更新了apt-get。
答案 0 :(得分：3)
以下内容使得alsa音频后端在Ubuntu上为我工作。
按照http://cournape.github.io/audiolab/installing.html#installation-from-sources中的指示，安装alsa标头：
$ sudo apt-get install libasound2-dev
在源目录中，
/path-to/scikits.audiolab-0.11.0 /
或者，如果使用pip（默认情况下将源下载到/ tmp）
/tmp/pip-build/scikits.audiolab
创建一个site.cfg文件，除[sndfile]部分外，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列表查找asoundlib.h（include_dirs）和libasound.so（library_dirs）在系统中的位置。
好吧，在完成所有这些并尝试重新安装之后，它仍然无法正常工作。我不断收到同样令人沮丧的消息：
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，我不得不使用这个黑客。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')()
与
alsa_info = info_factory('alsa', ['asound'], ['asoundlib.h'],
classname='AlsaInfo')()
如果这适用于更多人，我们可以请David Cournapeau（scikits.audiolab作者）制作此补丁。
