尽管安装了 python-pyaudio，但仍出现“ImportError：没有名为 pyaudio 的模块”

我正在尝试运行一个使用 pyaudio 的 Python 程序：

  1. 我下载了该程序（来自 Github因为 .deb 太旧了）
  2. 我安装python-pyaudio
  3. 我运行该程序
  4. 该计划称ImportError: No module named 'pyaudio'

我究竟做错了什么？

    import pyaudio

环境：

$ which python
/usr/bin/python
$ python --version
Python 2.7.11+

问题的根源在于runanki的https://github.com/dae/anki/blob/master/runanki明确声明 Python 3，因此./runanki会调用 Python 3 解释器，但您已pyaudio为 Python 2 安装。因此，Python 3 无法找到pyaudio，因此引发。这里最简单的解决方案是通过运行以下命令ImportError安装 Python 3 绑定：pyaudio

sudo apt update && sudo apt install python3-pyaudio
