• 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
    

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
