无法在 Windows 上更新 ghc

Question

尝试使用 ghc ( ghcup install ghc 9.4.3 ) 更新 ghcup 会导致错误：

这是日志说的：

我尝试使用 curl 命令，他们说会导致 powershell (curl.exe -fL -o "C:\ghcup\tmp\ghcup-3da46c8d7d5a204f\ghc-9.2.5-x86_64-unknown-mingw32.tar.xz. tmp" "https://downloads.haskell.org/~ghc/9.2.5/ghc-9.2.5-x86_64-unknown-mingw32.tar.xz") 它还会引发错误："curl: (35) schannel : 接下来 InitializeSecurityContext 失败: 未知错误 (0x80092012) -"

Answer 1

您可以通过GHCUP_CURL_OPTS环境变量将选项传递给 Curl。

根据谷歌翻译，错误代码后的俄语“子错误”消息为“吊销 function 无法对证书执行吊销检查”。 因此，传递更安全--ssl-revoke-best-effort或失败的--ssl-no-revoke标志可能就足够了，它只会关闭撤销检查，而不是-k标志这允许完全不安全的连接。

简而言之，在 PowerShell 中，您可能会发现运行它就足够了：

$Env:GHCUP_CURL_OPTS = '--ssl-revoke-best-effort'

在运行ghcup之前。

不过，吊销检查失败有点令人担忧。 如果您尝试通过 web 浏览器访问https://downloads.haskell.org ，您会遇到类似的错误吗？
