I was getting the same error when trying to install biopython with Python 3.7 on Windows 10.
尝试在 Windows 10 上使用 Python 3.7 安装 biopython 时遇到了同样的错误。
Installing just the Build Tools (instead of the full Community Edition as suggested in the other answer), with the options "C++/CLI support" and "VC++ 2015.3 v14.00 (v140) toolset for desktop" checked in addition to the defaults, solved the problem.
仅安装构建工具（而不是另一个答案中建议的完整社区版），除了默认值外，还选中了“C++/CLI 支持”和“VC++ 2015.3 v14.00 (v140) 桌面工具集”选项，解决了这个问题。
