一python库下载换源pip1.换清华源pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple2.查看换源是否成功显示下载频道看是否有清华源pip config list二conda换源添加频道conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/ conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r/ conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/msys2/ conda config --set show_channel_urls yes三linux的conda换源1.编辑文件nano ~/.condarc2.粘贴内容channels: - conda-forge - defaults show_channel_urls: true default_channels: - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r custom_channels: conda-forge: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud auto_activate: true保存ctrloenterctrlx3.显示频道# 默认的源官方 conda config --show default_channels # 换的源 conda config --show custom_channels四apt换源1.备份原来的源以防改错原文件无法还原sudo cp /etc/apt/sources.list.d/ubuntu.sources /etc/apt/sources.list.d/ubuntu.sources.bak2.编辑源文件sudo nano /etc/apt/sources.list.d/ubuntu.sources3.配置粘贴如下内容Types: deb URIs: https://mirrors.tuna.tsinghua.edu.cn/ubuntu Suites: noble noble-updates noble-backports Components: main restricted universe multiverse Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg Types: deb URIs: https://mirrors.tuna.tsinghua.edu.cn/ubuntu Suites: noble-security Components: main restricted universe multiverse Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg4.更新一下软件库sudo apt update sudo apt upgrade -y5.验证cat /etc/apt/sources.list.d/ubuntu.sources备选换源一个命令到位sudo sed -i s|http://archive.ubuntu.com|https://mirrors.tuna.tsinghua.edu.cn|g /etc/apt/sources.list.d/ubuntu.sources sudo sed -i s|http://security.ubuntu.com|https://mirrors.tuna.tsinghua.edu.cn|g /etc/apt/sources.list.d/ubuntu.sources
