Haskell 依赖地狱
Haskell dependency hell
我正在尝试在 Haskell 项目中包含特定版本的库。该库是住宿加早餐的（用于 martix 操作），但我需要特定版本 0.4.3，它修复了乘法实现的错误。
所以，我的 stack.yaml 看起来像这样：
flags: {}
extra-package-dbs: []
packages:
- .
extra-deps:
- bed-and-breakfast-0.4
- base-4.6.0.1
resolver: lts-12.8
但是我在构建时遇到了这个错误：
Error: While constructing the build plan, the following exceptions were encountered:
In the dependencies for bed-and-breakfast-0.4:
base-4.11.1.0 from stack configuration does not match >=4.5 && <4.7 (latest matching version
is 4.6.0.1)
needed due to realworldhaskell-0.1.0.0 -> bed-and-breakfast-0.4
Some different approaches to resolving this:
* Set 'allow-newer: true' 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 C:\Users\info\Desktop\Projects\haskell\stack.yaml:
- base-4.6.0.1
我已经完成了建议的操作，但没有解决任何问题。我试过使用不同的解析器来查看我的 GHCi 版本是否有问题，但没有任何效果。解释此类错误消息的最佳方式是什么？我应该如何继续？
编辑：
如果我删除 -base.4.6.0.1 并添加 allow-newer: true 我得到这个：
WARNING: Ignoring out of range dependency (allow-newer enabled): base-4.11.1.0. bed-and-breakfast requires: >=4.5 && <4.7

好的，所以我猜住宿加早餐库需要 base 4.11.1.0，它包含在 GHCi 6.10.2 中（根据 https://wiki.haskell.org/Base_package），所以我需要一个与之匹配的解析器GHCi 版本。我在哪里可以找到解析器版本？
这是对最新可用 bed-and-breakfast 包的限制：base (>=4.5 && <4.7)，这意味着它可能甚至无法使用高于 7.6 的 GHC 版本进行编译。考虑到在 GHC 7.8 之前甚至没有 LTS 快照，你运气不佳。
换句话说，软件包已过时，您的选择是：
- 提交问题并希望维护者能做些什么
- 尝试自己使用更新的 ghc
- 使用不同的包
