在树莓派上的CMake安装问题

Question

即时通讯在运行树莓派的树莓派3上安装CMake时遇到了一些麻烦。

运行命令时，我不断收到此错误消息

sudo apt-get install build-essential cmake pkg-config

错误信息：

> " Reading package lists... Done  Building dependency tree Reading
> state information... Done  Package CMake 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
> 
> E: Package 'cmake' has no installation candidate "

我尝试了其他安装方法，例如“ pip install cmake ”和“ sudo apt-get install -y cmake ”，但都无济于事。 你们能帮我吗？ 我可以从中提取图书馆吗？

先感谢您。

我正在运行在树莓派3上安装的raspbian Stretch 2018-03-13。
