(追記)
pipenvをuserインストールしてなかっただけ
pip3 install --user pipenv
pipenv install jupyterlab
pipenv run jupyter lab
2021年7月21日 本当にできた。
権限変更だけでは対応されない。
pipenvを使う必要がありそう.
以下は使わない。
この記事は？
macbookで環境構築をしているとたまに遭遇するjupyter notebookの500エラーの解決方法.
原因は、マルチユーザを使用している場合の権限問題。
結論は、以下のおまじないで権限付与することで解消する。
マルチユーザ環境で環境構築する場合は以下のコマンドを事前に通しておくのが基本(らしい)
> sudo chown -R $(whoami):admin /usr/local/*
Password:
> sudo chmod -R g+w /usr/local/*

解決方法
マルチユーザの場合は以下のおまじないが必要
> sudo chown -R $(whoami):admin /usr/local/*
Password:
> sudo chmod -R g+w /usr/local/*
無事開けました。
