haskell - Stack 无法安装 intero

Question

我刚刚安装了 Stack 使用

curl -sSL https://get.haskellstack.org/ | sh

安装顺利，但尝试使用 Stack 安装 Intero 时失败

ffriis@BNEC02QR6Y0G8WN ~> stack install hlint intero

Error: While constructing the build plan, the following exceptions were encountered:

In the dependencies for intero-0.1.32:
    ghc-8.4.4 from stack configuration does not match >=7.8 && <=8.4.3  (latest matching version is 8.4.3)
needed since intero is a build target.

Some different approaches to resolving this:

  * Set 'allow-newer: true' in /Users/ffriis/.stack/config.yaml to ignore all version constraints and build anyway.

  * Consider trying 'stack solver', which uses the cabal-install solver to attempt to find some working build configuration. This can be convenient when dealing with many complicated constraint
    errors, but results may be unpredictable.

  * Recommended action: try adding the following to your extra-deps in /Users/ffriis/.stack/global-project/stack.yaml:

ghc-8.4.3@sha256:07ee8fb5dab414c35f93d5d5afc1ecaa65a49c409346e5063436cc8b838cd754

Plan construction failed.

我已按照说明编辑了文件，但仍然出现相同的错误。解决问题的最佳方法是什么？

目前intero支持GHC 8.4.3 ，但堆栈正在抓取 8.4.4 .将您的解析器更改为 lts-12.14在 stack.yaml
