无法为 lambdacat 安装 happy for gtk2hs-buildtools

Question

所以我想在 win 上构建 https://github.com/baldo/lambdacat 。

无法在 Windows 上构建 happy（按照说明）。这是一个日志：

C:\Program Files\Haskell Platform\lambdacat>cabal install happy

当我尝试直接 cabal install lambdacat 时，我得到了非常糟糕的日志结尾

cabal: Error: some packages failed to install:

setup.exe: The program perl is required but it could not be found.

您需要安装 Perl。 ActiveState 有一个适用于 Windows 的发行版。
