python

pip换为国内源

准备给我的jupyter notebook加个自动补全功能，网上说要装个pip install jupyter_contrib_nbextensions

结果运行了两次都报pip._vendor.urllib3.exceptions.ReadTimeoutError: HTTPSConnectionPool(host='files.pythonhosted.org', port=443): Read timed out.

这就是因为网不好，嗯，就是网不好，可没有什么墙。。。

0.几个国内源

https://pypi.hustunique.com/simple/华中理工大学

1.临时修改

直接执行命令：

1
pip install pythonModuleName -i https://pypi.douban.com/simple

2.修改默认配置

需要修改~/.pip/pip.conf。

修改 pip.conf 文件 (没有就创建一个)

1
%APPDATA%\pip\pip.ini

修改内容如下：

# 在`.pip` 目录创建并编辑 `pip.conf`
# `pip` 安装需要使用的 `https` 加密，所以在此需要添加 `trusted-host`

[global]
# trusted-host = mirrors.ustc.edu.cn
index-url = https://mirrors.ustc.edu.cn/pypi/web/simple

修改文件后，执行命令发生错误

使用非HTTPS加密源（如豆瓣源），在执行命令发生错误，在命令最后加上--trusted-host pypi.douban.com

1
pip install django -i https://pypi.douban.com/simple --trusted-host pypi.douban.com

3.在pycharm中创建Django失败-2020.1.06更新

我想在pycharm2017中直接创建Django项目，前两个方法均不起作用，依然报错443超时

所以，针对Windows10，有了第三种修改方法。

下载的过程，可以看到，默认情况下，最后是pythonhosted.cn这个域名中下载文件出了问题，这是python官方的域名，对应的网站是在国外。

按照pip的官方说明文档，它的配置文件应该放在%APPDATA%/pip/目录下，配置文件名称是pip.ini，我们先按下win+R键。或者在开始菜单上点右键，点运行。然后在出来的窗口中输入%APPDATA%，然后点击确定。

我的电脑打开的是C:\Users\HP\AppData\Roaming，在这个目录下没有看到pip目录，因此需要手动创建一个。

进入pip文件夹，创建一个pip.ini，写入

[Global]
index-url = https://pypi.douban.com/simple
[install]
use-mirrors =true
mirrors =https://pypi.douban.com/simple/
trusted-host =pypi.douban.com

配置文件配置好以后，点击文件，再点击保存。然后就可以关闭文件编辑框了。

然后重新使用pycharm创建Django项目，稍候就能看到，下载成功。

4.实测

我是用的临时修改的方法，

实测效果不错
