Haskell環境構築
haskell+devcontainerの環境構築でハマった
まずhaskellだけならfeatures/src/haskell at main · devcontainers-contrib/features · GitHubではいる
がhlsのversionと、stackで使われているghcのversionが合わないといけない
GHC version support — haskell-language-server 2.9.0.1 documentation
いくつか方法がある
❓Dockerfile内でghcupを普通にインストール(2025/06/04時点ではfeaturesの方が良い)
Haskeller のための開発環境構築 on GitHub Codespaces #Docker - Qiita
Dockerfileはghcup-hs/scripts/bootstrap/bootstrap-haskell at master · haskell/ghcup-hs · GitHubを見て設定
ghcupのenv設定も参照
stack install implicit-hie && gen-hie > hie.yaml でhie.yamlを作ると動いた
動いてない!?!?! cannot satisfy -package taskmaster-0.1.0.0(use -v for more information) が出てきた。
Could not load module / Cannot satisfy -package error for exe/test/bench component whose main lib doesn't build or was not built · Issue #366 · haskell/haskell-language-server · GitHub
Intermittent "failed to load packages, cannot satisfy -package <main-lib>" from components other than <main-lib> · Issue #735 · haskell/haskell-language-server · GitHub
1-3 1. HLS をなんとしても動かす｜AtCoder ガチ言語 Haskell 🔥
HLS は簡単に動作しないかもしれません。時間的余裕をみて環境構築しましょう。
だよね...
Stackのresolverを中心に組み立てるべきかもしれない(実際にbuildするところなので)
https://www.stackage.org
nightlyにしてたら1夜にして動かなくなってた...
LTSにしたほうが良い絶対
✅Devcontainersのfeatures(2025/06/04時点の正解)
ghcのversionを合わせてみる
code: stack.yaml
resolver: nightly-2024-07-08
code: devcontainer.json
"ghcr.io/devcontainers-contrib/features/haskell:2": {
"globalPackages": "hlint",
"ghcVersion": "9.10.1"
}
だめ...(hlsの起動が失敗する)
というか設定したversionのghcも入っていないし話にならない
✅2025/05/22 Devcontainersに色々fixが入っていたのでリトライ

なんかdevcontainerの構築に鬼の時間がかかる。
まあ、行けた。ちょっと試してみよう。
またハマりそうだったら、haskellまた諦めようかな。
hlsも動いている感動
⏳Haskell + Nix
