任何haskell堆栈命令在windows上都会失败，其内容如下: HostCannotConnect "127.0.0.1“

Question

例如：

> stack ghci
Writing implicit global project config file to: C:\sr\global-project\stack.yaml
Note: You can change the snapshot via the resolver field there.
HttpExceptionRequest Request {
host                 = "s3.amazonaws.com"
port                 = 443
secure               = True
requestHeaders       = [("Accept","application/json")]
path                 = "/haddock.stackage.org/snapshots.json"
queryString          = ""
method               = "GET"
proxy                = Nothing
rawBody              = False
redirectCount        = 10
responseTimeout      = ResponseTimeoutDefault
requestVersion       = HTTP/1.1
}
(InternalException (HostCannotConnect "127.0.0.1" [Network.Socket.connect: <socket: 508>: failed (Connection refused (WSAECONNREFUSED))]))

来自同一个控制台的curl命令在解析url时没有问题。

> curl https://s3.amazonaws.com/haddock.stackage.org/snapshots.json


StatusCode        : 200
StatusDescription : OK
Content           : {"lts-2":"lts-2.22","lts-10":"lts-10.9","lts-9":"lts-9.21","lts-4":"lts-4.2","lts-3":"lts-3.22","lts-5":"lts-5.18","lts":"lts-11.0","lts-0":"lts-0.7","nightly":"nightly-2018-03-16","lts-1":"lts-1.15",
....

试图在另一台PC上安装相同的版本--没有这样的问题。

有什么想法吗？
