任何想法如何解决这个问题？

Answer 1

看起来像zlib-conduit软件包没有正确下载。删除下载，然后再试一次：

1. find out where your cabal directory is
   1. 开始ghci的
   2. :m System.Directory
   3. getAppUserDataDirectory "cabal"
2. 删除packages\hackage.haskell.org\zlib-conduit子目录的阴谋目录
3. 运行cabal update
4. 重新运行cabal install yesod-platform

（第3步可能是不需要的，但不会伤人。）
