在SO上，这是一个真正流行的问题，但是我看过的所有答案中，没有一个能清楚地说明此错误的真正含义以及发生的原因。

造成混淆的一个原因是，当您（例如）这样做时pip install pycparser，您首先会得到以下错误：

然后出现以下消息，说明该软件包是：

Successfully installed pycparser-2.19。

# pip3 install pycparser

当我尝试“pip install pyaudio”时，我收到了该错误。\n我收到了“pip install numpy”和“pip install wheel”，但这些并没有解决我的问题。

pip 版本：23.2.1\npython 版本：3.12.0

今天我从 ppa 存储库ppa:deadsnakes/ppa在 Ubuntu 22.04 上安装了新的 Python 3.12 ，一切正常，但是当我尝试使用命令python3.12 -m pip install somelibrary安装某些库时，出现以下错误
