我查看了 Stack Overflow 建议的其他帖子以及有关此问题的一些 Google 结果.我已经尝试使用 C++ 桌面模块安装和重新安装 VS Community 2019，使用 C++ 构建工具的 Visual Studio 构建工具，最新的 Windows 10 SDK 和所有选项以及最新的 rustup-init 安装.我的问题可能出在哪里?

I've looked at other posts suggested by Stack Overflow as well as some Google results regarding this issue. I've tried to install and reinstall VS Community 2019 with C++ for desktop module, Visual Studio build tools with C++ build tools, the newest Windows 10 SDK with all options as well as the newest rustup-init installation. Where might my problem be?

推荐答案

经过多次反复试验后，我发现我之前已经在 GNU 中安装了 mingw.即使 rust 在...Microsoft Visual Studio\2019\BuildTools\VC\Tools\MSVC..."中寻找 link.exe，它也使用 GNU 版本而不是某些依赖项的 MSVC 版本.因此，在我的情况下，不使用默认安装(用于 VS 附带的 MSVC)安装，而是使用来自 https://forge.rust-lang.org/infra/other-installation-methods.html 为我工作.也许如果有经验的人可以用正常的术语解释这个问题以备将来参考.

After a lot of trial and error I discovered that I had previously installed mingw with GNU. Even if rust looked for link.exe in "...Microsoft Visual Studio\2019\BuildTools\VC\Tools\MSVC...", it was using GNU version not MSVC version of some dependencies. So in my case using not default(which is for MSVC which comes with VS) installation, but an GNU platform specific rust installation from https://forge.rust-lang.org/infra/other-installation-methods.html worked for me. Maybe if someone experienced could explain the issue in normal terms for future reference.
