有没有人设法获得 Yorgey 等人的“未绑定”库,用于使用带有绑定的语法,安装最新的 GHC (7.0.3) 和 Haskell 平台?尝试 cabal install unbound,我得到以下信息:
Resolving dependencies...
cabal: cannot configure unbound-0.2.3. It requires base >=4.3 && <5
For the dependency on base >=4.3 && <5 there are these packages: base-4.3.0.0
and base-4.3.1.0. However none of them are available.
base-4.3.0.0 was excluded because of the top level dependency base -any
base-4.3.1.0 was excluded because of the top level dependency base -any
任何人都知道解决方案/解决方法,或者这里可能发生什么?
