安装haskell-platform，获取错误

Question

我试图安装haskell-platform

brew木桶安装haskell平台

但得到了以下错误。你是怎么修好的？

==> Satisfying dependencies
==> Downloading https://haskell.org/platform/download/8.2.1/Haskell%20Platform%2

最近，惠普8.2.1发布了一个新的二进制版本，并在haskell咖啡馆列表上宣布：https://mail.haskell.org/pipermail/haskell-cafe/2017-October/127979.html

这改变了哈希。正如错误消息中所指出的，"brew更新“应该更新平台木桶，并引入新的哈希，这应该允许事情继续正常进行。
