我在matplotlib venn中使用easy_install时遇到问题。我在windows电脑上使用python2.7。我怀疑路径不正确，但我不知道如何解决这个问题。有人能帮我吗？我将附加尝试在CMD提示器中运行easy_install命令的输出。

尝试pip安装建议的输出：

看来你有网络问题。你的机器是在防火墙或代理服务器后面运行的吗？
为了使easy_install在代理之后工作，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，可以使用-proxy参数。关于代理后面的pip使用的更多详细信息，请参阅本线程：如何在认证代理后面的窗口上使用pip
我认为这是您的解决方案
easy_install pip
pip install matplotlib-venn
easy_install 中没有模块matplotlib-venn
对于未来，使用pip为python安装任何软件包。

对我来说，rtree包也发生了同样的错误，我进行了缓存搜索并安装了liraries
在cloudera box的情况下，如果您正在尝试，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 vm jut，请按照说明操作，然后尝试通过easy_install安装。
