ubuntu 18.04安装anaconda3

1.下载安装包

https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/

或是

https://www.anaconda.com/distribution/#download-section

下载了Anaconda3-2019.10-Linux-x86_64.sh

2.安装

cd /下载
bash Anaconda3-2019.10-Linux-x86_64.sh

3.安装过程一直按Enter，最后提示 Do you wish the installer to initialize Anaconda3 by running conda init ? 输入 no，回车

4.修改环境变量

vim ~/.bashrc

确保conda initialize中路径配置的和真实系统中的路径一致。

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/home/xl/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
    eval "$__conda_setup"
else
    if [ -f "/home/xl/anaconda3/etc/profile.d/conda.sh" ]; then
        . "/home/xl/anaconda3/etc/profile.d/conda.sh"
    else
        export PATH="/home/xl/anaconda3/bin:$PATH"
    fi
fi
unset __conda_setup
# <<< conda initialize <<<

5.命令行输入conda info 显示的activate地址不对，修改

命令行输入：conda activate anaconda3安装的正确的地址

conda activate /home/xl/anaconda3

6.验证安装成功

命令行输入:python3

输出：

Python 3.7.4 (default, Aug 13 2019, 20:35:49) 
[GCC 7.3.0] :: Anaconda, Inc. on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> 

ubuntu系统本地python3是3.6版本，anaconda3安装包的python版本是3.7.

验证成功。
