うわぁ……。これまた環境構築からやり直さないとダメっぽい。辛い思い出しかない。絶対ヤダ。Python本体やパッケージ管理のためにpyenvとかanyenvとかdockerとか、管理ツールから構築しないとならない。そして、それらの使い方も学ばねば……。設定にはBashでシェル書かねば、とか広がって……。いつになったら初められるの；；ってなって……。うっ、頭が……。
所感
この世にPythonがはびこるとき、必ずや挫けるという絶望の環境構築。
苦労してPython環境をつくっても、OSアップデートでOSごとぶっ壊れる。そういう経験をしてきた。もう嫌だ。Pythonで苦労したくない。楽にコード書きたいからPython使っているのに。公式ドキュメントといい、なぜかPythonまわりの文書には欺瞞が満ちている印象がある。簡単とか嘘つくのはやめてくれ。少なくとも私は超絶に苦労した。もう騙されないからな。
こうして心の壁をつくっておかないとトラウマスイッチが入るレベル。ヘビ恐い。
