我試圖更新我的哈希克爾堆棧從8.0.2版本安裝ghc版本到8.2.1,但似乎我缺少的東西。升級哈希克爾堆棧正在使用的ghc版本
[[email protected] ~]$ stack --resolver ghc-8.2.1 setup
stack will use a sandboxed GHC it installed
For more information on paths, see 'stack path' and 'stack exec env'
To use this GHC and packages outside of a project, consider using:
stack ghc, stack ghci, stack runghc, or stack exec
[[email protected] ~]$ stack ghci
Configuring GHCi with the following packages:
GHCi, version 8.0.2: http://www.haskell.org/ghc/ :? for help
Loaded GHCi configuration from /tmp/ghci7878/ghci-script
Prelude> :q
Leaving GHCi.
我想我需要做一些額外的步驟後更新ghc版本的堆棧,但我不知道。
