在ghc解压缩时，运行stack install yesod-bin --install-ghc失败，并显示以下消息：“解压缩C：\ Users \ user \ AppData \ Local \ Programs \ stack \ x86_64-windows \ ghc-8.4.4.tar.xz时出现问题” < / p>
在创建带有yesod-sqlite模板的项目后，我尝试在Windows 10 64位cmd，最新的Haskell平台版本8.6.5-core-x86_64上运行此命令。我也尝试了不同的版本，但结果相同。 stack install yesod-bin-1.4.11 --install-ghc
> stack install yesod-bin --install-ghc

stack build在同一时间重试并失败。我希望可以进行一些适当的安装。
更新：stack setup --verbose输出：

另一种阴谋诡计的安装尝试表明，该网络软件包根本不愿意在Windows中编译，至少在通用命令提示符（cmd）中不愿意，但它需要MingW，MSys或Cygwin。我尝试使用后者进行自我更新，但成功了。然后仍然在Cygwin中，我再次尝试了堆栈安装，并且成功了。
不幸的是，stack命令的输出未提供任何有关Cygwin的提示，使我一阵子毫无头绪。但是，在Cygwin中，Yesod可以构建并启动，并且演示网站可以正常运行。也许对通用Windows命令提示符的某些强调可能有助于避免这种误解。
