安装完毕之后， source ~/.bashrc即可生效


===== 一键式sh脚本自动完成安装 =====
<code shell install_conda.sh>
#!/bin/bash

mkdir -p ~/tmp
cd ~/tmp

echo "正在下载 Miniconda 安装包..."
wget https://mirrors.tuna.tsinghua.edu.cn/anaconda/miniconda/Miniconda3-latest-Linux-x86_64.sh -O Miniconda3-latest-Linux-x86_64.sh

if [ ! -f Miniconda3-latest-Linux-x86_64.sh ]; then
    echo "下载失败，请检查网络或 URL 是否正确。"
    exit 1
fi

echo "正在安装 Miniconda..."
bash Miniconda3-latest-Linux-x86_64.sh -b -p $HOME/miniconda3

if [ ! -d $HOME/miniconda3 ]; then
    echo "安装失败。"
    exit 1
fi

echo 'export PATH="$HOME/miniconda3/bin:$PATH"' >> ~/.bashrc

$HOME/miniconda3/bin/conda init bash

echo "正在配置清华大学 TUNA 镜像源..."
cat > ~/.condarc << EOF
