介绍

通常来说，要安装conda有以下三种安装方案：

Miniconda

Miniconda 是 conda 的免费最小安装程序。它是 Anaconda 的一个小型引导版本，仅包含 conda、Python、它们都依赖的包以及少量其他有用的包（例如 pip、zlib 等）。

Anaconda Distribution

Anaconda Distribution 是一个功能齐全的安装程序，附带一套用于数据科学的软件包，以及 Anaconda Navigator（一个用于 conda 环境的 GUI 应用程序）。

Miniforge

Miniforge 是由 conda-forge 社区维护的安装程序，已预先配置为与 conda-forge 通道一起使用。

安装

脚本

mkdir -p ~/miniconda3
wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh -O ~/miniconda3/miniconda.sh
bash ~/miniconda3/miniconda.sh -b -u -p ~/miniconda3
rm -rf ~/miniconda3/miniconda.sh

初始化

脚本

~/miniconda3/bin/conda init bash

细节

lwk@qwfys:~$ ~/miniconda3/bin/conda init bash
no change     /home/lwk/miniconda3/condabin/conda

modified      /home/lwk/.bashrc==> For changes to take effect, close and re-open your current shell. <==lwk@qwfys:~$

执行上述脚本以后，用户目录下的文件.bashrc中会添加如下内容

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/home/lwk/miniconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; theneval "$__conda_setup"
elseif [ -f "/home/lwk/miniconda3/etc/profile.d/conda.sh" ]; then. "/home/lwk/miniconda3/etc/profile.d/conda.sh"elseexport PATH="/home/lwk/miniconda3/bin:$PATH"fi
fi
unset __conda_setup
# <<< conda initialize <<<

我们重新打开一个终端窗口，就会正常使用conda命令了，如下所示：

lwk@qwfys:~$ conda
