• 配置

  • 初始化^[1] Anaconda（安装时初始化了则跳过）

    # 如果如果anaconda安装初始化时，选择的no，那现在应该还用不了conda命令
# 执行 source $ANACONDA_HOME/bin/activate, 如：
source /usr/envs/anaconda3/bin/activate
# 初始化
conda init


  • 关闭启动时激活Conda基础环境（可选）

    # 如果您不希望在启动时激活Conda基础环境，将AUTO_ACTIVATE_BASE参数设置为FALSE：
conda config --set auto_activate_base false


  • Anaconda 镜像配置
    
    点击前往Anaconda 镜像配置

卸载

• 删除Anaconda 文件夹

  # rm -rf $ANACONDA_HOME，如：
rm -rf /usr/envs/anaconda3


• 删除Anaconda 配置

  # 打开配置文件
vim ~/.bashrc# 删除下面这段配置# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/usr/envs/anaconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
eval "$__conda_setup"
else
if [ -f "/usr/envs/anaconda3/etc/profile.d/conda.sh" ]; then
. "/usr/envs/anaconda3/etc/profile.d/conda.sh"
else
export PATH="/usr/envs/anaconda3/bin:$PATH"
fi
fi
unset __conda_setup
# <<< conda initialize <<<


• 更新配置文件

  source ~/.bashrc
或者 source /etc/profile
