macでシェルをfishに変えてpyenvとpipが上手くできなかったときの対処法 #Bash

概要

bashからfishに変えてから，以前まではできていた，pyenvでpythonのインストールとpipでパッケージのインストールができなくなったのでその対処法を紹介します．

事象

例えば下記のようなエラーが発生しています．

pip install selenium                        30.8s

opensslそもそもある？

$ which openssl
/usr/local/opt/openssl/bin/openssl

ありますね．．．

解決方法

opensslが失敗しているので，読み込めてない可能性があります．

config.fishに以下を追記

~/.config/fish/config.fish

set -x PATH /bin $PATH  # なければ追加
set -x PATH /usr/local/bin $PATH  # なければ追加
set -x PATH /usr/local/opt/openssl/bin $PATH  # 一番重要

プロファイルの適用

$ source ~/.config/fish/config.fish

pythonのインストール

無事pythonをインストールするっことができました
