Answer 1

检查您的互联网连接。

似乎无法访问互联网。不太可能，PyPi遇到了临时问题，您应该稍后尝试连接。

Answer 2

一步一步的非常简单的方法： -

从http://www.lfd.uci.edu/~gohlke/pythonlibs/

matplotlib(.whl)

matplotlib还需要numpy，dateutil，pytz，pyparsing，cycler，setuptools

过程：打开＆gt; python27＆gt;＆gt;脚本＆gt;复制并粘贴matplotlib.whlfile
在python27上打开cmd＆gt;脚本＆gt; pip install matplotlib-1.5.1-cp27-none win_amd64.whl

我认为这是最简单的安装方法。如果再遇到同样的问题，请尝试一下然后ping我。

Answer 3

另一种可能的解决方案 - 我找到了一个可执行安装程序here

以前没有在Google找到它。

Answer 4

尝试忽略缓存：

pip install matplotlib --no-cache

不知道它是如何工作的，因为当它说ConnectionTimeoutError时，我以为它没有使用缓存。如果此方法对任何人都有效，我希望听到一个解释。

Python pip：无法安装matplotlib（ConnectTimeoutError）
