Answer 1

Read timed out
下载超时了，天朝的网络就这样。做程序员真心不容易。
只有修改pip源了。
临时使用：pip install pythonModuleName -i https://pypi.douban.com/simple
修改默认的软件源：
修改/etc/pip.conf 文件，即可为所有用户配置．
修改~/.pip/pip.conf为当前用户配置．
windows下pip配置文件为C:Usersxxpippip.ini，没有就新建．

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

目前常用源有：

• 清华大学　http://pypi.tuna.tsinghua.edu...

• 中国科学技术大学　https://pypi.mirrors.ustc.edu...
