python易于安装的问题

Question

我使用easy_install for matplotlib-venn时遇到问题.我在使用python2.7的Windows计算机上.我怀疑路径不正确,但我不知道如何解决这个问题.谁能帮助我？我正在尝试在CMD提示符中运行easy_install命令附加输出.

C:\Python27\Scripts>easy_install matplotlib-venn

尝试pip安装建议的输出:

基于

Download error on https://pypi.python.org/simple/matplotlib-venn/: [Errno 11004] getaddrinfo failed 

和

Cannot fetch index base URL https://pypi.python.org/simple/ 

看来你有网络问题.您是在防火墙或代理后面运行机器吗？

例如,easy_install要在代理后面工作,您必须设置所需的环境

set http_proxy="user:password@server:port"
set https_proxy="user:password@server:port"

对于pip,你可以使用-proxy参数.关于代理背后的pip使用的更多细节请参见此主题:如何在身份验证代理后面的窗口上使用pip
