pyenvでpython3.7.1のインストール時にOpenSSL関連のエラーが起こったときの対応メモ #Python

自分用メモ書きです。(原因の究明とかはしてません)
Scrapboxからコピペして軽く整えただけなのでガタガタですごめんなさい。
(いい感じのConverter作って欲しい…)

環境

対応

エラー内容の中のURLを参照していかの対応をした

[https://github.com/pyenv/pyenv/wiki/Common-build-problems Common build problems · pyenv/pyenv Wiki]

$ set CFLAGS -I(brew --prefix openssl)/include
$ set LDFLAGS -L(brew --prefix openssl)/lib
$ pyenv install 3.7.1

しかしエラー内容は変わらず

ここで別の対応を発見

Python 3.7.0 :: The Python ssl extension was not compiled. Missing the OpenSSL lib? · Issue #1184 · pyenv/pyenv

$ brew install 'openssl@1.1'
$ CONFIGURE_OPTS="--with-openssl=$(brew --prefix openssl@1.1)" pyenv install 3.7.0

結局

とりあえずWARNING(WARNING: Please make sure you remove any previous custom paths from your /Users/<USER_NAME>/.pydistutils.cfg file.)に対応することに…

$ rm /Users/<USER_NAME>/.pydistutils.cfg

無事インストール完了

$ pyenv versions
* system (set by /Users/kaito/.pyenv/version)
  3.7.0

しっかりと削除してからインストールし直さなきゃダメですね…
