python pip异常

[playgithub]

Env

• OS：Windows
• Python：3.9.5
• Pip: 21.1.2

Qv2ray设置：

• Inbound Settings
  • SOCKS Settings: diabled
  • HTTP Settings: enabled

Problem

除了pip，网页或命令行都可以正常使用
测试命令：python -m pip install --upgrade pip
如果不开qv2ray，一切正常
如果开qv2ray，报错如下 (没有设置HTTP_PROXY或HTTPS_PROXY)

这不是 core 的问题。这是因为 Qv2ray 设置系统代理的格式是 '127.0.0.1:port'，手动改成 'http://127.0.0.1:port' 形式的就没问题了。否则，Python 会把 https 协议转发到 'https://127.0.0.1:port'，然而这是个 http 代理。

谢谢
在哪儿改？

[TIMESTICKING]

同问，在哪改。我在入站设置那改了，直接无法启动了

[CoreJK]

我找到了配置方法了，如下面图所示修改即可：

[playgithub]

没在用了，无法测试，还是谢谢。

试试将 C:/Users/用户名/AppData/Roaming/pip/pip.ini 改为：

[global]
index-url = http://mirrors.aliyun.com/pypi/simple/
[install]
trusted-host = mirrors.aliyun.com

[playgithub]

原来这样的，不行

[global]
timeout = 6000
index-url = https://mirrors.aliyun.com/pypi/simple/
trusted-host = mirrors.aliyun.com

刚改成下面这样，可以

[global]
timeout = 6000
index-url = https://mirrors.aliyun.com/pypi/simple/
[install]
trusted-host = mirrors.aliyun.com

不知为什么？

[ztnp]

第一个和第二个不是一样吗？
之所以添加 pip.ini 是因为 pip https 使用代理有问题，把 trusted-host 加上，index-url 可不用 https了

贴错了，已改

之所以添加 pip.ini 是因为 pip https 使用代理有问题，把 trusted-host 加上，index-url 可不用 https了

还是用https吧
