Matplotlib在Mac OSX 10.8 Mountain Lion上安装失败

Question

我试图在我的MacBook Air上安装matplotlib,但它总是给我这个错误信息:

我尝试使用自制软件安装freetype和libpng,但它不起作用.我怎样才能获得ft2build.h？

Answer 1

下面根据来自指示安装Python后就职于matplotlib安装thegreenroom.安装Python后,这些说明对我不起作用.我按照Scipy.org的说明安装了numpy和scipy.然后我做了(改编自上面的答案):

brew install freetype
brew install libpng

但是,无论是安装pip install matplotlib还是尝试从源代码安装,我都收到了相同的错误消息

python setup.py build
python setup.py install

在我通过克隆的matplotlib目录中git clone https://github.com/matplotlib/matplotlib.git.

错误一直持续到我跑了

brew link freetype

然后从克隆的matplotlib目录中运行

python setup.py build
python setup.py install

安装成功了.

Answer 2

这可能有助于人们寻找非自制的解决方案.

我的目标:pip install用于为非系统python 2.7.3构建构建matplotlib.

截至2013年2月,使用最新的X-Code和X-Code命令行工具,无论我尝试过什么样的体操,在使用gcc编译ft2build时,我总是收到与C++ ostream相关的模板错误.

我能够获得一个pip安装来使用以下环境变量:

export CC=clang
export CXX=clang++
export LDFLAGS="-L/usr/X11/lib"
export CFLAGS="-I/usr/X11/include -I/usr/X11/include/freetype2"

我只是强迫clang并添加了我的xquartz路径.没有额外的pkg-config或libpng构建,没有sudo-ed符号链接.

Answer 3

我认为其他答案都在正确的轨道上,但我遇到了同样的问题,可以证明:

brew install pkg-config
brew install freetype
pip install matplotlib

会产生相同的结果.通常在Ubuntu盒子上我的下一个响应就是

sudo apt-get install libfreetype-dev

或者安装标题的一些变体.但是,我找不到这样的自制软件包.此外,我能够在我的系统上一个非常正常的位置找到有问题的头文件:

zoidberg:~ matt$ locate ft2build.h
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk/usr/X11/include/ft2build.h
/usr/X11/include/ft2build.h

所以我怀疑我的系统路径有问题,或者使用自制软件包matplotlib.由于我很懒,我只是尝试从github安装matplotlib包头:

pip install git+git://github.com/matplotlib/matplotlib.git#egg=matplotlib-dev

它对我有用.

请注意“no pkg-config”通知。您的搜索路径上应该有pkg-config，并且它可能需要是自制版本，以便它知道库的自制版本在哪里。
