Python - 在 Mac OSX Snow Leopard 中安装 matplotlib

Question

我在安装 matplotlib 时遇到了问题。我遇到了与许多其他主题类似的错误，但这些解决方案都没有为我工作。我曾尝试通过 pip 和 git 安装 matplotlib，但每次我都会收到相同的错误，非常感谢帮助。

Answer 1

我遇到了同样的问题。我用酿造。我通过这样做解决了这个问题

brew install freetype
brew link freetype
brew install libpng
brew link libpng
brew install matplotlib

默认情况下，brew 使您的系统版本的 freetype 和 libpng 处于活动状态，这也是您需要执行“brew link”的原因。希望对您有所帮助。

更新：我现在建议使用 Anaconda Python 的免费版本。那么这是微不足道的。

Answer 2

我强烈建议通过包管理器而不是尝试自己编译源代码。这样效率更高。

一个不错的替代自制软件是著名的MacPorts 包管理器：

sudo port install py27-matplotlib

我过去曾使用过Fink，它是 OS X 的第三个主要包管理器，我发现 MacPorts 明显更加强大和最新。

网络上有很多 OS X 包管理器之间的比较（包括一些 nice ones），以便您更好地决定提交给哪个管理器。

您可以使用homebrew 轻松做到这一点：

$ brew install python
$ brew install gfortran
$ brew install pkg-config
$ easy_install pip
$ pip install numpy
$ cd $HOME
$ git clone https://github.com/matplotlib/matplotlib.git
$ cd matplotlib
$ python setup.py build
$ python setup.py install
