使用 Python 3 扩展安装 cwiid

Question

我正在尝试下载并安装带有 Raspberry Pi 3B+ 扩展名的 cwiid 包。但我不断收到这个错误。

pi@raspberrypi:~ $ sudo pip3 install cwiid

任何想法我做错了什么？我确实研究了这个主题，并在 github 上发现了一些关于 Python 3 扩展的聊天，但它涵盖了不同的错误消息。

编辑： 我在 pip 命令之前运行 sudo apt-get install libcwiid1 libcwiid1-dev 但收到以下错误消息

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package libcwiid1-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  libcwiid-dev

E: Package 'libcwiid1-dev' has no installation candidate

我认为这是最初的问题来自？

Answer 1

您似乎缺少 cwiid 标头。尝试使用安装它们

sudo apt-get install libcwiid1 libcwiid1-dev

然后重新运行您的 pip3 命令。
