此时配置如下
pip.ini

[global]
index-url = https://pypi.python.org/simple/

问题未解决
1.尝试修改国内，国际源。都无法正常下载。依然出现刚开始的错误。

#国内源
https://mirrors.aliyun.com/pypi/simple
pip install --index-url https://pypi.tuna.tsinghua.edu.cn/simple/ pyswisseph
pip install --index-url https://mirrors.aliyun.com/pypi/simple pyswisseph
pip install --index-url https://pypi.mirrors.ustc.edu.cn/simple/ pyswisseph

#国外源

#index-url = https://pypi.python.org/simple/

测试指令

尝试pip指定proxy，仍然报错

pip --proxy 主机号:端口号 install 下载的内容

pip --proxy 143.110.233.140:4780 install --index-url https://mirrors.aliyun.com/pypi/simple pyswisseph

此时可以安装成功的原因是有cache，（这个执行结果是下载成功后重新复测的）

尝试过无用的解决失败的解决方法
1.IE代理设置
在这里插入图片描述

2.win10代理设置
在这里插入图片描述

方法一

关键文件

修改后立即生效，无需重新cmd（windows10）

C:\Users\HASEE\AppData\Roaming\pip
pip.ini

[global]
index-url = https://pypi.python.org/simple/
proxy = http://127.0.0.1:4780
trusted-host = pypi.org

最终结果：

下载速度突破1MB限制

开启proxy程序选择节点即可

在这里插入图片描述

方法二

此配置需要如下使用。

[global]
proxy = http://mirrors.aliyun.com/pypi/simple/
index-url = https://pypi.tuna.tsinghua.edu.cn/simple/

pip --proxy 127.0.0.1:4780 install --index-url https://mirrors.aliyun.com/pypi/simple pyswisseph
pip --proxy 127.0.0.1:4780 install --index-url https://pypi.org/simple/ flatlib
pip --proxy 127.0.0.1:4780 install --index-url https://pypi.python.org/simple/ flatlib

备注：
—中途遇到某个依赖无法下载成功，可以使用此指令单独下载
pip install --index-url https://pypi.python.org/simple/ flatlib
–此行代码proxy没有生效。
