出現エラー

Error while finding module specification for ‘virtualenvwrapper.hook_loader’ (ModuleNotFoundError: No module named ‘virtualenvwrapper’) virtualenvwrapper.sh: There was a problem running the initialization hooks. If Python could not import the module virtualenvwrapper.hook_loader, check that virtualenvwrapper has been installed for VIRTUALENVWRAPPER_PYTHON=/Users/username/opt/anaconda3/bin/python and that PATH is set properly.

一番最初のパス

.bashrc

export WORKON_HOME=$HOME/.virtualenvs
source /usr/local/bin/virtualenvwrapper.sh

.bash_profile

if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

変更後

.bashrc

export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python

export WORKON_HOME=~/Env

source /usr/local/bin/virtualenvwrapper.sh

からの、ファイル再読み込み

source ~/.bashrc

これで先ほどのエラーは解消されました
