Нужно ли использовать код bash, добавленный в ~ / .bash_profile от anaconda?

Question

После того как я установил anaconda в Mac OS X, я получил следующее приложение к ~ / .bash_profile. Мне интересно, какова цель conda shell.bash hook (вывод показан ниже). Достаточно ли просто добавить /Users/xxx/opt/anaconda3/bin/ в $ PATH. Вместо того чтобы использовать код bash, добавленный к ~/.bash_profile?

__conda_setup="$(CONDA_REPORT_ERRORS=false '/Users/xxx/opt/anaconda3/bin/conda' shell.bash hook 2> /dev/null)"
if [ $? -eq 0 ]; then
    \eval "$__conda_setup"
else
    if [ -f "/Users/xxx/opt/anaconda3/etc/profile.d/conda.sh" ]; then
        . "/Users/xxx/opt/anaconda3/etc/profile.d/conda.sh"
        CONDA_CHANGEPS1=false conda activate base
    else
        \export PATH="/Users/xxx/opt/anaconda3/bin:$PATH"
    fi
fi
unset __conda_setup

export CONDA_EXE='/Users/pengy/opt/anaconda3/bin/conda'
