Hakyll教程出错

Question

我正在按照 https://jaspervdj.be/hakyll/tutorials/01-installation.html.

中的 Hakyll 教程进行操作

但是好像有点不对劲，说不出来是什么。当我运行 'stack init' 我收到这条消息。

Looking for .cabal or package.yaml files to use to init the project.
Using cabal packages:
- ./

Selecting the best among 16 snapshots...

        - ourblog-com requires ==4.13.*

Selected resolver: lts-14.16
Resolver 'lts-14.16' does not have all the packages to match your requirements.
    hakyll not found
        - ourblog-com requires ==4.13.*

This may be resolved by:
    - Using '--omit-packages' to exclude mismatching package(s).
    - Using '--resolver' to specify a matching snapshot/resolver

我的路径似乎正确包含在内。为什么会这样？

Answer 1

Hakyll 维护者似乎没有在 Stack 存储库中保持最新。创建 my-site 目录后，手动创建一个 stack.yaml 文件，而不是运行ning stack init，其中包含以下行：

resolver: lts-14.16
packages:
- .
extra-deps:
- hakyll-4.13.0.1

然后运行 stack build，依此类推。这似乎有效。
