我希望安装软件包。

Answer 1

地区限制： 如果您在伊朗并尝试安装软件包，您应该知道：

1-如果您在远程服务器上执行此操作，某些伊朗服务器的访问会受到限制，并且您必须使用 VPN。

2-如果您尝试在个人计算机上安装该软件包，您的互联网服务提供商的访问可能会受到限制

3-如果您确定以上情况都不是，请确保您的路由器或计算机上未激活受 IP 范围限制的 VPN。

4-此外，此问题可能是由于您系统上的 DNS 设置造成的。

网络限制：

1-也许你可以在运行

-i

命令时使用

pip install

选项解决这个问题

2-也许您必须使用代理来安装软件包：

python -m pip install PackageName --proxy="theProxy:thePort"

这是一个可供伊朗人访问的免费代理网站，也许您可以使用它，也许您想要自己使用高级代理。
