pipenvでsslエラー

pipenv syncで ssl エラー

pipenv syncで環境構築を行おうとしたところ，ssl エラーが発生した．その解決策を未来の自分に向けて残しておく．

環境

• MacBook Pro (M1, 2020)
• macOS Sonoma 14.0
• Python 3.10.11
• pip 23.3.1
• pipenv, version 2023.10.24

問題点

pipenv syncで環境を構築しようとしたところ，以下のエラーが発生した．

解決策

brewが使えるなら，以下のコマンドを実行する．

terminal

brew install openssl@1.1

今まではbrew install opensslでインストールしていたが，これで install されていたのはopenssl3だった．openssl@1.1が必要らしいので改めてインストールした．

これを行うとしっかりとpipenv syncが通るようになった．
