Rubyの開発環境をアップデートした時のメモ

2021/01/17に公開

久しぶりにRubyを触りたくなったので、個人環境のRubyをアップデートする。

最新版のRubyをインストールする

rbenvのアップデート

rbenvはanyenv経由でインストールしてあるのでanyenv-updateが使える。
anyenv-updateについてはこちらを参照。
https://github.com/znz/anyenv-update

$ anyenv update                                                         
Skipping 'anyenv'; not git repo
Updating 'anyenv/anyenv-update'...
Updating 'rbenv'...
Updating 'rbenv/ruby-build'...
Updating 'anyenv manifest directory'...

Rubyのインストール

現時点での最新版は3.0.0になる。

$ rbenv install --list

2.6.6
2.7.2

jruby-9.2.14.0
mruby-2.1.2
rbx-5.0

3.0.0をインストールする。

 $ rbenv install 3.0.0

VSCode用の設定を確認

VSCodeのlintで使うgemをインストールしなおす

VSCode拡張のrubyの設定も変わっているらしかったので、settings.json修正。
古い設定はこちらを参照。
https://github.com/rubyide/vscode-ruby/blob/master/docs/legacy.md

    ...省略
    "ruby.lint": {
        "rubocop": true,
        "reek": true
    },
    "ruby.format": "rubocop",
    ...省略

おわり

とりあえずlinterとdebuggerの動作が出来ることを確認して終わり。
