Rubyのirbで、エラーがおきました。いろいろ調べて最終的に解消できました。

<internal:C:/Ruby31-x64/lib/ruby/site_ruby/3.1.0/rubygems/core_ext/kernel_require.rb>:88:in `require’: 126: 指定されたモジュールが見つかりません。 - C:/Ruby31-x64/lib/ruby/gems/3.1.0/gems/fiddle-1.1.1/lib/fiddle.so (LoadError)

irbでfiddleが影響するとは！？

Windowsで、irbエラー

エラー解消方法

1. Rubyへのパスが通ってるか？ → pathで ;C:\Ruby31-x64\bin; が含まれていること
2. コマンドプロンプトを管理者権限で起動
3. gem update --system 実行
4. fiddle を再インストール
5. gem uninstall fiddle
6. gem install fiddle
7. 再度irbを起動
