【Python】pip安装加速：使用国内镜像源

零、使用命令行设置

设置全局镜像源

随便使用下面任一命令即可！

阿里云：

pip config set global.index-url https://mirrors.aliyun.com/pypi/simple/

豆瓣：

pip config set global.index-url https://pypi.douban.com/simple/

清华大学：

pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple/

中国科学技术大学：

pip config set global.index-url https://pypi.mirrors.ustc.edu.cn/simple/

遇到的问题，信任镜像源

最新版的pip要求必须使用https，如果源不是https协议的，会报如下错误：

WARNING: The repository located at … is not a trusted or secure host and is being ignored.

WARNING: The repository located at mirrors.aliyun.com is not a trusted or secure host and is being ignored. If this repository is available via HTTPS we recommen
d you use HTTPS instead, otherwise you may silence this warning and allow it anyway with '--trusted-host mirrors.aliyun.com'.
ERROR: Could not find a version that satisfies the requirement requests (from versions: none)
ERROR: No matching distribution found for requests                                           
WARNING: The repository located at mirrors.aliyun.com is not a trusted or secure host and is being ignored. If this repository is available via HTTPS we recommen
d you use HTTPS instead, otherwise you may silence this warning and allow it anyway with '--trusted-host mirrors.aliyun.com'.
WARNING: There was an error checking the latest version of pip.

解决方案一：切换为https的源（推荐）

一般在链接中把http替换成https即可，或者找对应的https源。

解决方案二：临时信任

可以在命令行后加上--trusted-host参数，例如：

pip install -i http://mirrors.aliyun.com/pypi/simple/ 依赖参数 --trusted-host mirrors.aliyun.com

壹、使用文件设置

Windows上按Windows+R键打开运行，输入%userprofile%打开个人文件夹，在个人文件夹中新建.pip目录，在目录中新建文本文档并改名为pip.conf，写入如下内容：

阿里云（http）

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

阿里云（https）

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

其他的源也是类似的，把链接改一下即可：

• 豆瓣：https://pypi.douban.com/simple/
• 清华大学：https://pypi.tuna.tsinghua.edu.cn/simple/
• 中国科学技术大学：https://pypi.mirrors.ustc.edu.cn/simple/
