installation finished.

文件安装完毕.

Do you wish the installer to initialize Anaconda3
by running conda init? [yes|no]
[no] >>>

默认为no，直接回车.

You have chosen to not have conda modify your shell scripts at all.
To activate conda's base environment in your current shell session:eval "$(/home/clyde/anaconda3/bin/conda shell.YOUR_SHELL_NAME hook)" To install conda's shell functions for easier access, first activate, then:conda initIf 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!===========================================================================

安装脚本执行结束.

2.3 设置环境变量

激活base虚拟环境.

$ source ~/anaconda3/bin/activate
(base) $

初始化shell设置.

(base) $ conda init

conda init 命令实质是在~/.bashrc末尾添加以下内容：

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

设置启动shell时不自动激活base环境.

(base) $ conda config --set auto_activate_base false

2.4 测试

重新启动或打开新的终端.

$ conda --version
conda 4.9.2

安装成功.
