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 +扩展的cwiid软件包。但是我一直收到此错误。

pi@raspberrypi:~ $ sudo pip3 install cwiid

知道我做错了什么吗？我确实研究了这个话题，并在github上找到了一些关于Python 3扩展的聊天，但它涵盖了不同的错误消息。

编辑：我在 pip 命令之前运行了 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

我想这是最初的问题来自哪里？

Answer 1

看起来你缺少 cwiid 标头。尝试使用

sudo apt-get install libcwiid1 libcwiid1-dev

，然后重新运行pip3命令。
