安装

Anaconda是一个免费开源的Python和R语言的发行版本，用于计算科学（数据科学、机器学习、大数据处理和预测分析），Anaconda致力于简化软件包管理系统和部署。Anaconda的包使用软件包管理系统Conda进行管理。超过1200万人使用Anaconda发行版本，并且Anaconda拥有超过1400个适用于Windows、Linux和MacOS的数据科学软件包。 -wikipedia

• 下载

  • Anaconda 官网下载：https://www.anaconda.com/products/individual#Downloads
  • 清华大学开源软件镜像站：https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/

  Tips: Anaconda官网是外国网站，速度非常慢，建议去清华大学开源软件镜像站下载

• 安装（Linux）

  • 授权并执行

    # 给下载的sh文件执行权限
    chmod a+x Anaconda3-2021.05-Linux-x86_64.sh

    If you'd prefer that conda's base environment not be activated on startup, 
    set the auto_activate_base parameter to false: 
    
    conda config --set auto_activate_base false
    
    Thank you for installing Anaconda3!

配置

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

• 初始化^[1] Anaconda（安装时初始化了则跳过）

  # 执行 source $ANACONDA_HOME/bin/activate, 如：
  source /usr/sdk/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
  

  关闭前效果（默认）
  

  关闭后效果（false）
  

• Anaconda 镜像配置

  • https://www.cnblogs.com/librarookie/p/15376578.html

• 配置 环境和 包存放目录

  # 查看所有配置
  conda config --show
  
  # 查看环境(envs_dirs) 或包(pkgs_dirs) 配置
  conda config --show envs_dirs
  conda config --show pkgs_dirs
  
  # 配置目录(第一次用 --add，后面修改使用 --set)
  conda config --add envs_dirs /path/to/envs_dir
  conda config --add pkgs_dirs /path/to/pkgs_dir
  
  # 查看 conda 配置
  conda config --show-source
  

  

  Tips: 上述的操作就是在 conda 的配置文件 ~/.condarc 中添加 envs_dirs 和 pkgs_dirs 配置，故直接编辑 ~/.condarc 效果一样;

卸载

• 删除Anaconda 文件夹

  # rm -rf $ANACONDA_HOME，如：
  rm -rf /usr/sdk/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/sdk/anaconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
  if [ $? -eq 0 ]; then
      eval "$__conda_setup"
  else
      if [ -f "/usr/sdk/anaconda3/etc/profile.d/conda.sh" ]; then
          . "/usr/sdk/anaconda3/etc/profile.d/conda.sh"
      else
          export PATH="/usr/sdk/anaconda3/bin:$PATH"
      fi
  fi
  unset __conda_setup
  # <<< conda initialize <<<
  

• 更新配置文件

  source ~/.bashrc
  # 或者 
  source /etc/profile
