python - 错误：尝试安装 pyOpt-1.2.0 时找不到 vcvarsall.bat

Question

我正在尝试将 python 包 pyOpt ( http://www.pyopt.org/ ) 安装到安装了 Python 3.9.5 的 Windows 10 机器上。我手动下载了文件并将它们存储在 /Lib/site-packages 中。然后我从 pyOpt 包目录运行以下命令：

python setup.py 安装

我遇到了一个问题，它说它无法找到 vcvarsall.bat。我已经阅读了 2013 年关于类似主题的主题，但它指的是 Python 2.7。

阅读 Stephen Dower 的这篇文章后，似乎 vcvarsall.bat 已链接到 Visual Studio。然后我安装了 Visual Studio 2015，但仍然看到错误。

作为参考，以下是命令行的输出：
