Question

我是Haskell的新手，想尝试使用酸状态库，但在尝试安装时会得到以下输出：

>cabal install acid-state
Resolving dependencies...
Configuring acid-state-0.7.5...
Building acid-state-0.7.5...
Preprocessing library acid-state-0.7.5...
[ 1 of 15] Compiling Data.Acid.CRC    ( src\Data\Acid\CRC.hs, dist\build\Data\Ac
id\CRC.o )
[ 2 of 15] Compiling Paths_acid_state ( dist\build\autogen\Paths_acid_state.hs,
dist\build\Paths_acid_state.o )
[ 3 of 15] Compiling Data.Acid.Archive ( src\Data\Acid\Archive.hs, dist\build\Da
ta\Acid\Archive.o )
[ 4 of 15] Compiling FileIO           ( src-win32\FileIO.hs, dist\build\FileIO.o
 )

src-win32\FileIO.hs:43:5:
    Not in scope: `catchIO'
    Perhaps you meant `catch' (imported from Prelude)

src-win32\FileIO.hs:55:6:
    Not in scope: `tryE'
    Perhaps you meant `try' (imported from Control.Exception.Extensible)

src-win32\FileIO.hs:56:6:
    Not in scope: `tryE'
    Perhaps you meant `try' (imported from Control.Exception.Extensible)
cabal: Error: some packages failed to install:
acid-state-0.7.5 failed during the building phase. The exception was:
ExitFailure 1

谢谢！

我遇到了同样的问题。临时解决方法：安装旧版本的酸状态

cabal install acid-state-0.7.0

如何让cabal安装酸状态？
