trusted-host = pypi.tuna.tsinghua.edu.cn

[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple/
trusted-host = pypi.tuna.tsinghua.edu.cn

# 设置默认镜像源
pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple/
pip config set install.trusted-host pypi.tuna.tsinghua.edu.cn

# 增加超时时间
pip install package_name --timeout 1000

# 增加重试次数
pip install package_name --retries 5

# 禁用pip版本检查
pip install package_name --disable-pip-version-check

# 查看缓存信息
pip cache info

# 清理缓存（解决缓存损坏问题）
pip cache purge

# 禁用缓存（某些情况下可以避免缓存问题）
pip install package_name --no-cache-dir

# 使用requirements.txt批量安装
pip install -r requirements.txt --timeout 1000

# 并行安装（Linux/macOS）
echo "package1 package2 package3" | xargs -n 1 -P 4 pip install

pip install --upgrade pip

pip install pipx
pipx install package_name

conda install package_name
conda install -c conda-forge package_name
