No instance for (NFData Version)
arising from a use of `rnf'
Possible fix: add an instance declaration for (NFData Version)
In the second argument of `seq', namely `rnf version'
In the expression: rnf name `seq` rnf version
In an equation for `rnf':
rnf (PackageIdentifier name version) = rnf name `seq` rnf version
Error during cabal-install bootstrap:
Compiling the Setup script failed.
实际上我需要更新cabal，但每次尝试都会失败。
我尝试了cabal install cabal-install并遇到了以下错误
cabal: cannot configure unix-2.7.0.1. It requires base >=4.5 && <4.8
For the dependency on base >=4.5 && <4.8 there are these packages:
base-4.5.0.0, base-4.5.1.0, base-4.6.0.0, base-4.6.0.1, base-4.7.0.0 and
base-4.7.0.1. However none of them are available.
附加说明：Centos 6.6
使用Cabal库的版本1.10.2.0的caball-install版本0.10.2
GHC版本7.0.4
哈斯克尔平台，2011.4.0.0-6.el6.x86_64
如何解决它请帮助我！
