Question

我想告诉你我尝试了什么，然后我非常欢迎你能提供关于如何正确设置PortAudio和PyAudio的评论！

我尝试从运行Snow Leopard的Core 2 Duo MacBook Pro安装their website的PortAudio的stable和svn版本。稳定版本的sizeof错误为can be fixed(?)，但每日svn版本与./configure && make && make install安装良好（所以这就是我正在使用的）。测试编译正确，我可以得到二进制文件以产生输出/可以读取麦克风输入。

好的，那么PyAudio就有麻烦了。从source安装我收到有关未找到库的错误：

我可以从their .dmg installer安装PyAudio，但它的目标是python2.5。如果我将/Library/Python/2.5/site-packages/的所有相关内容复制到/Library/Python/2.6/site-packages/（这包括PyAudio-0.2.3-py2.5.egg-info，_portaudio .so，pyaudio.py，pyaudio.pyc和pyaudio.pyo）然后我的python2.6可以识别它。

In [1]: import pyaudio
Please build and install the PortAudio Python bindings first.
------------------------------------------------------------
Traceback (most recent call last):
  File "<ipython console>", line 1, in <module>
  File "/Library/Python/2.6/site-packages/pyaudio.py", line 103, in <module>
    sys.exit(-1)
SystemExit: -1

Type %exit or %quit to exit IPython (%Exit or %Quit do so unconditionally).

因此无法导入_portaudio，因此会发生这种情况。如果我尝试直接导入它：

In [2]: import _portaudio
------------------------------------------------------------
Traceback (most recent call last):
  File "<ipython console>", line 1, in <module>
ImportError: /Library/Python/2.6/site-packages/_portaudio.so: no appropriate 64-bit architecture (see "man python" for running in 32-bit mode)

好的，所以如果我export VERSIONER_PYTHON_PREFER_32_BIT=yes然后再次运行python（好吧，我想是ipython），我们可以看到它有效但有后果：

In [1]: import pyaudio

In [2]: pyaudio
Out[2]: <module 'pyaudio' from '/Library/Python/2.6/site-packages/pyaudio.pyc'>

我们可以假设pylab之前正在工作！我花了一段时间才开始这么做，但有人可以帮助这个安装或从成功的Snow Leopard安装中获得建议吗？对于这篇长篇文章感到抱歉，但我只是因为提供部分信息而臭名昭着，我正试图解决这个问题！

Answer 1

感谢PyAudio的作者对我的查询的快速反应，我现在有一个安装得很好的副本。对于有类似问题的人，他的指示如下。

嗨，迈克尔，

试试这个：

1）确保你的目录布局是   像：

./ foo / pyaudio / portaudio-v19 / ./foo/pyaudio /

2）从源代码构建portaudio-v19，   就像你做的那样

3）cd ./foo/pyaudio/ 4）python   setup.py build --static-link

（参见顶部的评论   setup.py了解更多信息   --static链路）

如果一切顺利，请在里面   ./foo/pyaudio/build/lib.macosx-10.6-.../，   你会找到建造的（胖）物体   包括i386，ppc和x86_64   二进制文件。你也可以做一个“python   setup.py安装“如果你愿意。

最好，休伯特

Answer 2

我使用的是Mac 10.5.8 Intel Core 2 duo并遇到了同样的问题。您需要的目录布局是

./foo/pyaudio/portaudio-v19/
./foo/pyaudio

原因是setup.py具有以下内容： portaudio_path = os.environ.get（“PORTAUDIO_PATH”，“。/ portaudio-v19”）

或者，您应该能够设置PORTAUDIO_PATH env变量并使其工作。
