【问题描述】：

我正在使用 mint 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:
libraries asound not found in /usr/local/lib
libraries asound not found in /usr/lib
scikits/audiolab/soundio/setup.py:21: UserWarning: Alsa not found - alsa backend not build
warnings.warn("Alsa not found - alsa backend not build")
CoreAudioInfo:
scikits/audiolab/soundio/setup.py:31: UserWarning: CoreAudio not found - CoreAudio backend not build
warnings.warn("CoreAudio not found - CoreAudio backend not build")

当我执行“$locate asound”时，我得到了

如何让 setup.py 找到库。有什么我想念的吗？ 我见过http://forum.ubuntu-fr.org/viewtopic.php?pid=3748397和scikits.audiolab on Ubuntu Oneiric - ImportError: No module named _sndfile

这引起了很多挫折

更新

在我的一台 PC 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 后，此错误已消除。

【参考方案1】：

以下内容使 alsa 音频后端可以在 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（源默认下载到 /tmp）

/tmp/pip-build/scikits.audiolab

创建一个 site.cfg 文件，并在 [sndfile] 部分之外创建一个 [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 list 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 hack。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，我们可以要求David Cournapeau（scikits.audiolab 作者）制作此补丁。

【讨论】：

嗨@ravich2_7183，有趣的是你找到了解决这个问题的方法。当我有时间时，我会检查这个补丁/哎呀，现在正忙着做事。过去，我重新安装了很多东西以使 audiolabs 在我的 linuxMint13 上工作。我希望，我当时找到了这样的补丁。
