python容易安装的问题

Question

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

尝试 pip 安装建议的输出：

Answer 1

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/ 

您的网络似乎有问题。您在防火墙或代理后运行您的计算机吗？

要让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。有关代理背后 pip 使用的更多详细信息，请参见此线程：How to use pip on windows behind an authenticating proxy

Answer 2

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 安装任何 python 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库

如果您正在尝试使用 cloudera 框，那么这将按照 bugzile 中的方式工作。 https://bugzilla.redhat.com/show_bug.cgi?id=1510444 它适用于我的 cloudera vm，只需按照说明操作，然后尝试通过 easy_install 安装。

所以唯一的解决方案是破解源代码：
