【问题描述】：

我试图在 python 中使用终端安装 dubins 插件，但一直收到此错误。

我尝试过的事情

我的 python 版本是 3.9.0，适用于 Windows 10 x64
我的 setuptools 已升级
我尝试下载 tar.gz 文件，但出现了同样的错误。

之前尝试安装 dubins 时出现此错误：需要 Microsoft Visual C++ 14.0。我安装了 Visual C++ 2019 和 Windows 10 SDK，然后这就是我遇到的问题。

【问题讨论】：

您是否为 MS Studio 2019 安装了构建工具？
@pavel 是的，我做到了。您具体指的是哪些构建工具？我安装了所有 C++ 的
错误'tp_print': is not a member of '_typeobject' 表示该代码适用于不同版本的Python。 The home page 建议它适用于 Python、2.7 和 3.4-3.6。在 Python 3.8 中，tp_print 方法已从 API 中移除。

【解决方案1】：

对于以后发现这个问题的人来说，我最大的问题是我试图在 Windows 上运行 Linux 代码。我切换到 Linux，一切都立即开始工作。这就是我为你准备的一切。
