安装 slycot 问题 [Ubuntu 18.04]

Question

我正在尝试在 ubuntu 18.04 上安装 python slycot package。 但是，我无法找到做到这一点的方法。 我不断收到以下错误：

alemoreno@alejandro:~$ pip3 install slycot

      ********************************************************************************
      scikit-build could not get a working generator for your system. Aborting build.
      
      Building Linux wheels for Python 3.9 requires a compiler (e.g gcc).
      But scikit-build does *NOT* know how to install it on ubuntu
      
      To build compliant wheels, consider using the manylinux system described in PEP-513.
      Get it with "dockcross/manylinux-x64" docker image:
      
        https://github.com/dockcross/dockcross#readme
      
      For more details, please refer to scikit-build documentation:
      
        http://scikit-build.readthedocs.io/en/latest/generators.html#linux

  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for slycot
Failed to build slycot
ERROR: Could not build wheels for slycot, which is required to install pyproject.toml-based projects

以下是我正在使用的一些程序：

alemoreno@alejandro:~$ pip3 --version
pip 22.0.3 from /home/alemoreno/.local/lib/python3.9/site-packages/pip (python 3.9)

alemoreno@alejandro:~$ ninja --version
1.10.2.git.kitware.jobserver-1

它的位置：

alemoreno@alejandro:~$ whereis ninja
ninja: /usr/bin/ninja /home/alemoreno/.local/bin/ninja /usr/share/man/man1/ninja.1.gz

如果有人能帮助我，我将不胜感激，因为我在这个安装上浪费了很多时间，我需要开始实际使用它。

提前致谢。

我安装了 conda，它对我有用。

conda install -c conda-forge slycot
