我正在尝试使用 cabal 安装 leksah 作为我的开发环境,但我遇到了错误。
user@home:~$ cabal install leksah
Resolving dependencies...
cabal: Could not resolve dependencies:

有关在我的机器上安装 haskell 的其他详细信息如下 -
user@home:~$ ghci --version
The Glorious Glasgow Haskell Compilation System, version 8.2.1
user@home:~$ cabal --version
cabal-install version 1.24.0.2
compiled using version 1.24.2.0 of the Cabal library
user@home:~$ stack --version
Version 1.3.2, Git revision 3f675146590da4f3edf768b89355f798229da2a5 (4395 commits) x86_64 hpack-0.15.0
有什么建议可以解决这些错误吗?
