我在为 matplotlib-venn 使用 easy_install 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问题。有人可以帮我吗？我正在附加尝试在 CMD 提示器中运行 easy_install 命令的输出。

C:\Python27\Scripts>easy_install matplotlib-venn
Searching for matplotlib-venn

尝试 pip install 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。您是否在防火墙或代理后运行您的计算机？

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"

对于 pip，您可以使用-proxy参数。有关代理后面的 pip 使用的更多详细信息，请参见此线程：如何在身份验证代理后面的 Windows 上使用 pip

我认为这是您的解决方案

easy_install pip
pip install matplotlib-venn

matplotlib-venneasy_install 中没有模块

并且对于将来，使用 pip 为 python 安装任何包。

如果您正在尝试使用 cloudera 框，那么这将在 bugzile 中实现。 https://bugzilla.redhat.com/show_bug.cgi?id=1510444 它适用于我的 cloudera 虚拟机，请按照说明操作，然后尝试通过 easy_install 安装。

For me the same error occurred for rtree package and I did the cache search and installed the liraries
