はじめに
本記事は どすこい塾 Advent Calendar 2025 の19日目の記事です。
昨日も @uhooi で Unity as a LibraryでUnityからSwiftの処理を呼ぶ方法 でした。
miseのセットアップ方法を紹介します。
「mise」とは？
開発ツール、環境変数、タスクを管理するツールです。
asdf + direnv + makeのイメージです。
本記事ではmise本体と開発ツールに絞って説明します。
環境
- OS：macOS Tohoe 26.0
- Shell：Bash
- mise：2026.1.1 macos-arm64 (2026-01-08)
セットアップ
Getting Startedを参考に、miseをセットアップします。
miseのインストール
macOSの場合、Homebrewでのインストールが推奨されているので、それに従ってインストールします。
$ brew install mise
開発ツールのインストール
開発ツールごとに mise use --global {ツール}@{バージョン} コマンドを実行し、インストールとセットを行います。
以下はNode.jsをインストールする例です。
$ mise use --global node@24.12.0
インストールすると ~/.config/mise/config.toml の [tools] に書き込まれます。
~/.config/mise/config.toml
[tools]
+ node = "24.12.0"
アクティベート
対話型シェルの場合、 mise activate を使って node などの開発ツールを直接利用できるようにすることが推奨されています。
Bashの場合は以下を .bash_profile に追記します。
~/.bash_profile
+ # mise
+ # ref: https://mise.jdx.dev/getting-started.html#activate-mise
+ if [ -d "$HOME/.config/mise" ]; then
+ eval "$(mise activate bash)"
+ fi
先ほどインストールしたバージョンが使えたらアクティベートに成功しています。
$ node --version
v24.12.0
CI/CDやIDE、スクリプトなどの非対話型シェルでは、 shims を使うのが最適とのことです。
補完の設定
例えば mise install を補完するために mise ins で Tab キーを押下すると、 bash: command not found: _comp_initialize エラーが発生します。
❌補完を設定していないとエラーになる
$ mise ins # Tabキーを押下する
$ mise insbash: command not found: _comp_initialize
.bash_profile に以下を追記し、補完が効くように設定します。
~/.bash_profile
# mise
# ref: https://mise.jdx.dev/getting-started.html#activate-mise
if [ -d "$HOME/.config/mise" ]; then
eval "$(mise activate bash)"
+ eval "$(mise completion bash --include-bash-completion-lib)"
fi
しかしスクリプトに問題があるようで、たくさんのエラーが発生します。

補完は効くようになったので一旦よしとします。
✅補完が効く
$ mise ins # Tabキーを押下する
install install-into
$ mise install
miseで管理している開発ツールのバージョン出力
mise tool {ツール} --active コマンドを実行すると、miseで管理している開発ツールのバージョンを出力できます。
$ mise tool node --active
24.12.0
これを応用し、プロンプトに各開発ツールのバージョンを表示するとカッコいいかもしれません。
よかったら私の設定を参考にしてください。
おわりに
miseを使って node などの開発ツールを管理できるようになりました。
だいたいの開発ツールを一元管理できて便利です

明日は未定です。
