更改pip的默认服务器

2019独角兽企业重金招聘Python工程师标准>>>

pip是python的包管理工具，可以十分方便的下载安装各种python库，例如Django，Flask，Scrapy之类的，但是每次pip的时候总是会莫名其妙的timeout，而且下载速度及其缓慢。我觉得跟墙还是有一点关系的。 除了挂代理，那就只能

http://pypi.douban.com/ 豆瓣 （推荐使用）
http://mirrors.aliyun.com/pypi/ 阿里云（推荐使用，在我们学校不如豆瓣快Orz）
http://pypi.sdutlinux.org/ 山东理工大学 （已跪，听说是校领导干的） http://e.pypi.python.org/ 清华大学
http://pypi.hustunique.com/ 华中理工大学
http://pypi.mirrors.ustc.edu.cn 中国科学技术大学

##手动测试

<!-- lang: shell -->
pip install web2py -i http://pypi.douban.com/simple

##设为默认服务器： 打开～/.pip/pip.conf（注意如果遇到无法保存，请查看一下权限） 输入以下内容： [global] timeout = 6000 index-url = http://pypi.douban.com/simple/ 测试：

<!-- lang: shell -->
 sudo pip install Scrapy

如果显示以下信息，那么就算成功了（国内似乎没有支持HTTPS的pypi服务器）：
