本文详细阐述了在 Ubuntu 系统中安装 Anaconda3 的完整流程。包括 Anaconda3 安装包的获取途径，具体安装过程中的每一个步骤及注意事项，还有安装后的环境变量设置和安装成功的验证方法。旨在为 Ubuntu 用户提供清晰、易懂且准确的 Anaconda3 安装指南，帮助读者顺利完成安装，为后续的 Python 开发和数据处理工作奠定基础。 

1. 下载Anaconda

下载地址：

Anaconda | Anaconda Distribution

下载适合电脑Python版本和计算平台的版本。

2. 推荐切换到国内源

anaconda的源改为国内镜像, 配置文件是~/.condarc

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/
conda config --set show_channel_urls yes

pip源改为国内镜像, 配置文件是~/.pip/pip.conf, 该后的文件内容如下:

[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple/
[install]
trusted-host=https://pypi.tuna.tsinghua.edu.cn

update conda

conda update conda -y
conda update anaconda -y
conda update python -y
conda update --all -y

3. 安装 Anaconda

bash Anaconda3-5.3.0-Linux-x86_64.sh # make sure append the Anaconda executable 

一直按回车 

遇到下面的提示，按回车会安装到默认目录；

如果系统安装盘不够大，建议安装在其它挂载盘上，这里输入你想要安装的目录，然后按回车。

Anaconda3 will now be installed into this location:
/home/xxx/anaconda3

  - Press ENTER to confirm the location
  - Press CTRL-C to abort the installation
  - Or specify a different location below

遇到下面的信息表示安装成功

no change     /home/xueht/disk/anaconda3/condabin/conda
no change     /home/xueht/disk/anaconda3/bin/conda
no change     /home/xueht/disk/anaconda3/bin/conda-env
