当我安装hsqml时，出现以下错误：
cabal install hsqml Resolving dependencies... Configuring hsqml-0.3.4.1...

If the libraries are already installed but in a non-standard location then you can use the flags --extra-include-dirs= and --extra-lib-dirs= to specify where they are. cabal: Leaving directory 'C:\Users\wjsgm\AppData\Local\Temp\cabal-tmp-16012\hsqml-0.3.4.1' cabal: Error: some packages failed to install: hsqml-0.3.4.1 failed during the configure step.
