Problems with python easy install
提问by jonas
I have a problem using easy_install for matplotlib-venn. I'm on a windows computer using python2.7. I'm suspecting the path is not correct but I do not know how to fix the problem. Could anyone help me? I'm attaching the output from trying to run the easy_install command in the CMD prompter.

it seems that your have network issue. Do you run your machine behind a firewall or a proxy?
看来你有网络问题。您是否在防火墙或代理后面运行您的机器？
For easy_installto work behind proxy, you have to setup needed environments, for example
为了easy_install在代理后面工作，您必须设置所需的环境，例如
set http_proxy="user:password@server:port"
set https_proxy="user:password@server:port"
For pip you can use -proxyargument. More details on pip usage behind proxy see in this thread: How to use pip on windows behind an authenticating proxy
对于 pip，您可以使用-proxy参数。有关代理背后 pip 使用的更多详细信息，请参阅此线程：如何在身份验证代理后面的 Windows 上使用 pip

I think this is your solution
我认为这是你的解决方案
easy_install pip
pip install matplotlib-venn
No module matplotlib-vennin easy_install
matplotlib-venneasy_install 中没有模块
And for future, use pip for install any package for python.
对于未来，使用 pip 为 python 安装任何包。

For me the same error occurred for rtree package and I did the cache search and installed the liraries
对我来说，rtree 包发生了同样的错误，我进行了缓存搜索并安装了 liraries
