在运行 Snow Leopard 的 Mac 上构建 PortAudio 和 PyAudio（拱形问题）

Question

我想告诉你我的尝试，然后我非常欢迎你提供任何关于如何正确设置 PortAudio 和 PyAudio 的 cmets！

我已尝试为运行 Snow Leopard 的 Core 2 Duo MacBook Pro 从 their website 安装稳定版和 svn 版本的 PortAudio。稳定版本有 can be fixed(?) 的 sizeof 错误，但每日 svn 版本使用./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，我可以让二进制文件产生输出/可以读取麦克风输入。

好的，那么 PyAudio 有麻烦了。从source 安装我收到关于找不到库的错误：

我可以从their .dmg installer 安装 PyAudio，但它针对的是 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, and pyaudio.pyo) 那么我的python2.6就可以识别了。

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).

所以发生这种情况是因为_portaudio 无法导入。如果我尝试直接导入：

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），我们可以看到它可以工作，但会产生后果：

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 以前可以工作！我花了一段时间才走到这一步，但是有人可以帮助安装此安装，或者从成功的 Snow Leopard 安装中提供建议吗？很抱歉发了这么长的帖子，但我因只提供部分信息而臭名昭著，我正在努力解决这个问题！

Answer 1

感谢 PyAudio 的作者对我的询问的快速响应，我现在有了一个安装良好的副本。他的指导贴在下面，供遇到类似问题的人使用。

嗨，迈克尔，

试试这个：

1) 确保您的目录布局是 喜欢：

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

2) 从源代码构建 portaudio-v19， 正如你所做的那样

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

（见顶部的 cmets setup.py 了解更多信息 --static-link)

如果一切顺利，在里面 ./foo/pyaudio/build/lib.macosx-10.6-.../, 你会发现建造的（胖的）物体 包括 i386、ppc 和 x86_64 二进制文件。你也可以做一个“python setup.py install”，如果你喜欢的话。

最好的，休伯特

Answer 2

我在 Mac 10.5.8 Intel Core 2 duo 上遇到了同样的问题。 你需要的目录布局是

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

原因是 setup.py 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 环境变量并使其工作。
