＆＃34;无效的预处理指令＆＃34;安装memoize时

Question

我尝试跑步：

cabal install memoize

在终端，但我得到的是：

11 warnings and 1 error generated.
Failed to install memoize-0.6
cabal: Error: some packages failed to install:
memoize-0.6 failed during the building phase. The exception was:
ExitFailure 1

1错误是：

Data/Function/Memoize/TH.hs:5:6:
     error: invalid preprocessing directive
        #-}
         ^
