cabal无法读取bytestring cabal文件,用ghc 7.4.1

Question

我刚刚在32位linux上从GHC 7.2.2升级到7.4.1.安装很顺利,但cabal-install并不开心:

$ cabal update
Downloading the latest package list from hackage.haskell.org
$ cabal install repa
Resolving dependencies...
cabal: Couldn't read cabal file "bytestring/0.9.2.1/bytestring.cabal"

这是我正在运行的cabal版本:

$ cabal --version
cabal-install version 0.10.2
using version 1.10.1.0 of the Cabal library

谢谢!
