BUILD FAILED (macOS 13.5 on arm64 using ruby-build 20231114)

事象

• M2 Macで rbenv install 3.2.2 が通らない

解決策

• .bashrcにhomebrewのpathを明示する

export PATH="/opt/homebrew/bin:$PATH"

• .bashrcでRUBY_CONFIGURE_OPTSを指定する

export RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix openssl@1.1)"

---

原因と流れ

原因1(homebrewのpath)

.bashrcの記載を変えた際に、homebrewのpathを消去してしまっていた

homebrewでインストールしたライブラリが見つからないことがわかる。

解決策

export PATH="/opt/homebrew/bin:$PATH"

解決策

Loading the Ruby openssl extension failedで検索してみると、下記の記事を見つけました。(ありがとうございます！！)

記事に記載されていた下記のコマンドを実行で、無事ruby 3.2.2のインストールに成功

export RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix openssl@1.1)"
