3. 清除备份文件（存有疑问）

原因在于：

Anaconda-Clean creates a backup of all files and directories that might be removed in a folder named .anaconda_backup in your home directory. Also note that Anaconda-Clean leaves your data files in the AnacondaProjects directory untouched.

可是，在 spotlight 中没找到该备份，在 Macintosh HD 里也没找到。 猜想：因为先执行了 option B，后执行了 option A，所以那些备份已经被删除了。

4. Removing Anaconda path from .bash_profile

打开 .bash_profile，执行以下命令：

touch ~/.bash_profile
open ~/.bash_profile

将以下内容从 .bash_profile 中删除，而后保存。

# added by Anaconda3 2018.12 installer
# >>> conda init >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$(CONDA_REPORT_ERRORS=false '/Users/xuzhengfu/anaconda3/bin/conda' shell.bash hook 2> /dev/null)"
if [ $? -eq 0 ]; then
    \eval "$__conda_setup"
else
    if [ -f "/Users/xuzhengfu/anaconda3/etc/profile.d/conda.sh" ]; then
        . "/Users/xuzhengfu/anaconda3/etc/profile.d/conda.sh"
        CONDA_CHANGEPS1=false conda activate base
    else
        \export PATH="/Users/xuzhengfu/anaconda3/bin:$PATH"
    fi
fi
unset __conda_setup
# <<< conda init <<<
