安装matplotlib时出错

我已尝试使用pip install matplotlib,git clone然后python setup.py install按照Mac OS 10.7 的安装常见问题中所述.但是我得到了同样的错误:

[...]

好像我错过了我系统中安装的一些软件包？或者还有其他更好的安装matplotlib的方法吗？

谢谢!

更新:通过谷歌搜索和搜索SO我发现我可能缺少包freetype2,但是,如果我尝试通过自制软件安装它我收到一条警告消息:

[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.

我在Ubuntu服务器12.04上遇到了这个问题.

我必须安装libfreetype6-dev并libpng-dev从仓库.当我遇到这个问题时,我正在使用virtualenv并使用pip安装matplotlib.

我需要做的提示来自matplotlib安装中早期弹出的警告消息,因此请留意那些指示发现依赖关系的消息,而不是标题.

真棒.这有点帮助了.在OS X上,您可以使用"brew install freetype"

在Centos 6上,它是yum install freetype-devel libpng-devel

同样的错误,安装工作在我的一台Lion机器上,但不在另一台机器上.跟踪它到缺少pkg-config

$ brew install pkg-config
$ pip install -U 'http://sourceforge.net/projects/matplotlib/files/matplotlib/matplotlib-1.1.0/matplotlib-1.1.0.tar.gz/download'
