我无法通过pip使用终端下载slycot库。

Question

所以我试图通过pip下载slycot，但我总是收到错误。老实说，我并不完全熟悉终端提示符以及它是如何工作的。这是我运行时得到的结果，sudo -H pip3 install slycot

以下是终端使用该命令发布的内容：

  The project does not specify a build backend, and pip cannot fall back to setuptools without 'setuptools>=40.8.0' and 'wheel'.

You are using pip version 19.0.3, however version 20.0.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

我现在已经尝试了pip install scikit-build，这将返回

我也试过了，pip install cmake和这个返回

任何帮助都将不胜感激。

您在安装slycot时遇到了另一个错误，您依赖于skbuild。

为了修复它，请检查这个站点，它为您提供了skbuild包的编译后的二进制文件，然后重试，也可能是cmake

尝尝这个

pip install scikit-build; pip install cmake

你可以在这里阅读更多细节和方法来实现这一点。
