问题描述

我尝试按照中所述使用pip install matplotlib和git clone然后使用python setup.py install Mac OS 10.7的安装常见问题解答.但是我得到了同样的错误:

I've tried using pip install matplotlib and git clone then python setup.py install as described in the installation faq for Mac OS 10.7. But I get the same error:

似乎我缺少系统中安装的某些软件包?还是有其他更好的方法来安装matplotlib?

It seems like I'm missing some package installed in my system? Or there any other better way to install matplotlib?

谢谢！

更新:通过谷歌搜索并搜索SO，我发现我可能缺少软件包freetype2，但是，如果我尝试通过自制软件安装它，则会收到警告消息:

UPDATE: by googling and search on SO I've found that I might lack the package freetype2, however, if I try to install it by homebrew I get a warning message:

[me @ my mac]$ brew search freetype
Apple distributes freetype with OS X, you can find it in /usr/X11/lib.
However not all build scripts look here, so you may need to call ENV.x11
in your formula's install function.

推荐答案

我在Ubuntu服务器12.04上遇到了这个问题.

I had this issue on Ubuntu server 12.04.

我必须从存储库中安装libfreetype6-dev和libpng-dev.遇到此问题时，我正在使用virtualenv并使用pip安装matplotlib.

I had to install libfreetype6-dev and libpng-dev from the repositories. I was using a virtualenv and installing matplotlib using pip when I ran into this issue.

我需要这样做的提示来自于在matplotlib安装早期弹出的警告消息，因此请留意那些指示已找到依赖项的消息，而不是标题.

Hints that I needed to do this came from the warning messages that popup early in the matplotlib installation so keep an eye out for those messages which indicate a dependency is found, but not the headers.
