我正在尝试使用堆栈(lts-3.20)构建libssh2-hs,但出现一些错误:
$ stack build
No compiler found, expected minor version match with ghc-7.10.2 (x86_64-ncurses6) (based on resolver setting in /home/black/programmation/haskell/libssh2-hs/stack.yaml).
To install the correct GHC into /home/black/.stack/programs/x86_64-linux/, try running "stack setup" or use the "--install-ghc" flag.
$ stack setup
No information found for ghc-7.10.2.
Supported versions for OS key 'linux64-ncurses6': GhcVersion 7.10.3, GhcVersion 8.0.1, GhcVersion 8.0.2
我使用archlinux 64位,这里发生了什么,我能做什么?
