• 配置

  • 初始化^[1] Anaconda（安裝時初始化了則跳過）

    # 如果如果anaconda安裝初始化時，選擇的no，那現在應該還用不了conda命令
    # 執行 source $ANACONDA_HOME/bin/activate, 如：
    source /usr/envs/anaconda3/bin/activate
    # 初始化
    conda init
    

  • 關閉啟動時激活Conda基礎環境（可選）

    # 如果您不希望在啟動時激活Conda基礎環境，將AUTO_ACTIVATE_BASE參數設置為FALSE：
    conda config --set auto_activate_base false
    

  • Anaconda 鏡像配置
    點擊前往Anaconda 鏡像配置

卸載

• 刪除Anaconda 文件夾

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

• 刪除Anaconda 配置

  # 打開配置文件
    vim ~/.bashrc
  
  # 刪除下面這段配置
  
  # >>> 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
