解决方法，在内的Windows服务器打开克拉西，并且开启局域网链接，查看ip我的IP是：192.168.79.107

步骤 1: 设置代理服务器

在命令行中设置代理服务器：

export http_proxy=http://192.168.79.107:7890
export https_proxy=https://192.168.79.107:7890

步骤 2: 升级 pip

使用刚才设置的代理服务器来升级 pip：

python3.9 -m pip install --upgrade pip

验证安装

验证 pip 是否可以正常工作：

python3.9 -m pip --version

然后继续安装就行

取消代理命令：

unset http_proxy
unset https_proxy
