尝试运行使用pyaudio的python应用程序。使用virtualenv和安装正在运行。但是在运行时无法找到portaudio。但_portaudio.so文件存在。任何建议???

(venv) kidkic@pi-mirror1:~/audio $ jasper/jasper.py 
Could not import the PyAudio C module '_portaudio'.

Answer 1

问题不在于它找不到库，而是库缺少所需的功能。（source code）。我遇到了同样的问题，并认为问题源于使用错误版本的portaudio-dev进行构建。

您需要做什么：

如果你有sudo apt-get purge --remove python-pyaudio，请用./configure卸载python-pyaudio（这是版本0.2.8）
Download PortAudio的最新版本（19）。
解压并安装PortAudio
- make
- make install
- portaudio19-dev
获取pyaudio的依赖项
- python-all-dev
- python3-all-dev（ Python 3 的sudo pip install pyaudio）
{{1}}

之后，我能够使用pyaudio。

这对我有用

conda install -c anaconda portaudio

Answer 3

对于Linux用户，在安装Libraries have been installed in: /usr/local/lib If you ever happen to want to link against installed libraries in a given directory, LIBDIR, you must either use libtool, and specify the full pathname of the library, or use the `-LLIBDIR' flag during linking and do at least one of the following: - add LIBDIR to the `LD_LIBRARY_PATH' environment variable during execution - add LIBDIR to the `LD_RUN_PATH' environment variable during linking - use the `-Wl,-rpath -Wl,LIBDIR' linker flag - have your system administrator add LIBDIR to `/etc/ld.so.conf' See any operating system documentation about shared libraries for more information, such as the ld(1) and ld.so(8) manual pages. ---------------------------------------------------------------------- PortAudio was successfully installed. On some systems (e.g. Linux) you should run 'ldconfig' now to make the shared object available. You may also need to modify your LD_LIBRARY_PATH environment variable to include the directory /usr/local/lib

后，您可能会收到类似内容

sudo ldconfig

所以，我想按照Wehrdo的上述回答中的步骤，将以下命令添加为步骤4。

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
echo "export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/your/custom/path/" >> ~/.bashrc
var check = !$.trim( $('#div').html() ).length; if (check) { console.log('no html'); } else { console.log('some html'); }

Answer 4

当我用 conda 安装 pyaudio 时，错误就出来了。但是，当我通过 'pip install pyaudio' 用 pip 安装它时它就消失了

这个包的 conda 源似乎有问题。

Answer 5

问题是目前python 2.7、3.4、3.5和3.6主要支持portaudio和pyaudio。在您提出问题时，可能不支持 2.7。如果你想知道哪些版本的 python 是兼容的，你总是必须检查这个网站：https://pypi.org/project/PyAudio/#files。如果你想保持你的 python 版本相同，试试这个非官方的 Windows 站点：https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyaudio

Answer 6

Pip Unistall pyaudio Pipwin安装pyaudio 对于Windows机器

pyaudio无法导入_portaudio
