haskell-stack - 将平台从 8.0.1 升级到 8.0.2 后，堆栈不起作用

Question

升级haskell平台包后，stack命令不起作用。

$ stack path
No compiler found, expected minor version match with ghc-8.0.1 (x86_64) (based on resolver setting in /home/eii/exercism/haskell/linked-list/stack.yaml).
To install the correct GHC into /home/eii/.stack/programs/x86_64-linux/, try running "stack setup" or use the "--install-ghc" flag.
$

我尝试过堆栈设置，但它正在尝试下载旧的 GHC (ghc-8.0.1)。我刚刚安装了 Haskell 平台 8.0.2 (haskell-platform-8.0.2-unknown-posix--full-x86_64.tar.gz)。我使用的是 64 位 Linux。

$ stack setup
Preparing to install GHC to an isolated location.
This will not interfere with any system-level installation.
ghc-8.0.1:   15.69 MiB / 108.01 MiB ( 14.52%) downloaded...^Cuser interrupt
$

我可以用 ghc-8.0.2 编译并且 ghci 工作正常..但我不能使用堆栈也不能安装新包。

$ stack update
Downloading package index from https://s3.amazonaws.com/hackage.fpcomplete.com/00-index.tar.gz
Updating package index Hackage (mirrored at https://s3.amazonaws.com/hackage.fpcomplete.com/00-index.tar.gz) ...
$ stack upgrade

$ which ghc

$ ls -la /usr/local/bin/ghc

$

请帮忙。

前几天我在 Arch Linux 4.17.4 上遇到了这个问题。错误是:

No setup information found for ghc-8.4.3 on your platform.
This probably means a GHC bindist has not yet been added for OS key 'linux64-ncurses6', 'linux64-tinfo6'.
Supported versions: ghc-7.8.4, ghc-7.10.2, ghc-7.10.3, ghc-8.0.1, ghc-8.0.2, ghc-8.2.1, ghc-8.2.2, ghc-8.4.1, ghc-8.4.2

作为一种解决方法，我编辑了 stack.yml改变

lts-12.0

到

lts-11.15
