I tried to install freetype and libpng using homebrew but it doesn't work. How can I get ft2build.h?

我尝试使用homebrew安装freetype和libpng，但它不起作用。如何得到ft2building。h?

The following worked for matplotlib installation after installing python according to instructions from thegreenroom. Those instructions didn't work for me after I installed Python. I followed the instructions from Scipy.org to install numpy and scipy. Then I did (adapted from above answer):

根据greenroom的说明，安装python之后，下面的代码用于matplotlib的安装。在我安装了Python之后，这些指令对我不起作用。我按照Scipy.org上的说明安装numpy和scipy。然后我做了(改编自上面的回答):

brew install freetype
brew install libpng

However I got the same error message whether I installed with pip install matplotlib or trying to install from source, doing

但是，无论我安装了pip install matplotlib还是试图从源代码安装，我都得到了相同的错误消息

python setup.py build
python setup.py install

in the matplotlib directory I cloned via git clone https://github.com/matplotlib/matplotlib.git.

在matplotlib目录中，我通过git克隆了https://github.com/matplotlib/matplotlib.git。

The error persisted until I ran

错误一直持续到我跑

brew link freetype

Then from the cloned matplotlib directory I ran

然后从克隆的matplotlib目录中运行

python setup.py build
python setup.py install

And the installation succeeded.

和安装成功了。

This may help folks looking for a non-homebrew solution.

这可能有助于人们寻找非自制的解决方案。

My goal: use pip install to build matplotlib for a non-system python 2.7.3 build.

我的目标是:使用pip安装为非系统python 2.7.3构建matplotlib。

Using latest X-Code and X-Code command line tools as of Feb 2013, no matter what gymnastics I tried, I always received C++ ostream related template errors when compiling ft2build with gcc.

在2013年2月，使用最新的X-Code和X-Code命令行工具，无论我尝试了什么，在编译与gcc的ft2build时，我总是收到c++ ostream相关的模板错误。

I was able to get a pip install to work with the following env vars:

我可以得到一个pip安装，以配合下列env vars:

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

I simply forced clang and added my xquartz paths. No extra pkg-config or libpng builds, no sudo-ed symlinks.

我只是强行加入了clang并添加了xquartz路径。没有额外的pkg-config或libpng构建，没有sudo-ed符号链接。

I think the other answers are on the right track, but I encountered this same problem and can attest that:

我认为其他的答案是正确的，但是我遇到了同样的问题，可以证明:

brew install pkg-config
brew install freetype
pip install matplotlib

would yield the same result. Typically on an Ubuntu box my next response would have been

会产生同样的结果。通常在Ubuntu框上，我的下一个反应是

sudo apt-get install libfreetype-dev

or some variation of that to install the header. However, I could find no such homebrew package. Furthermore, I was able to locate the header file in question in a pretty normal location on my system:

或者安装头文件的一些变体。然而，我找不到这样的自制程序包。此外，我能够在我的系统中一个非常正常的位置找到问题的头文件:

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

So I suspect there's either a problem with my system paths or with the homebrew packaged matplotlib. Since I'm lazy, I just tried installing the matplotlib package head from github:

所以我怀疑我的系统路径或自制的打包matplotlib有问题。由于我很懒，所以我尝试从github上安装matplotlib包头:

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

and it worked for me.

这对我很有效。

Here's the brew + pip recipe I used from a cold start. If you already have python and gfortran and such, jump in at the point where you need. The crucial steps appear to be brew install freetype and brew install libpng prior to doing pip install matplotlib

这是我从冷开始使用的brew + pip配方。如果您已经有了python和gfortran等语言，请在需要的地方进行跳转。关键的步骤似乎是在执行pip安装matplotlib之前，先安装brew freetype和brew安装libpng

$ ruby -e "$(curl -fsSkL raw.github.com/mxcl/homebrew/go)"
$ brew doctor
$ brew install python
$ export PATH=/usr/local/bin:/usr/local/share/python:$PATH
$ easy_install pip
$ brew install gfortran
$ pip install numpy
$ pip install scipy
$ brew install pkg-config
$ brew install freetype
$ brew install libpng
$ pip install matplotlib
$ python
>>> import numpy
>>> import scipy
>>> import matplotlib

#5

Note the 'no pkg-config' notices. You should have pkg-config on your search path, and it presumably needs to be the homebrew version so that it knows where the homebrew versions of the libraries are.

注意“无pkg-config”通知。您应该在搜索路径上设置pkg-config，它可能需要是自制版本，以便它知道库的自制版本在哪里。

#6

You need freetype:

你需要freetype的:

brew install freetype

See the following:

I also use mac air with OS X ver 10.8.2.

我还使用mac air和OS X ver 10.8.2。

Using following commands can get rid of this failure:
brew install freetype
brew install libpng
pip install matplotlib

使用以下命令可以清除此故障:brew安装freetype brew安装libpng pip安装matplotlib。

That's all. There may be some warning in the installing process, but that does not affect.

这是所有。在安装过程中可能会有一些警告，但这并不影响。

Use following python code to test:

使用以下python代码进行测试:

import matplotlib.pyplot as plt
plt.plot([1,2,3,4])
plt.ylabel('some numbers')
plt.show()

I have found installing these pacakges via homebrew to be the most reliable method

我发现通过homebrew安装这些pacakges是最可靠的方法

 # if you haven't installed python via brew already:
 brew install python

 # sets up python as default python instead of system python
 brew link python

 # Add more brew formulae so we can install our py libs with brew
 brew tap samueljohn/python
 brew tap homebrew/science

 # install numpy,scipy,matplotlib and dependencies ( gfortran, etc.. )
 brew install numpy
 brew install scipy
 brew insatll matplotlib

I am using MacOs 10.8 too, and I encountered the same problem regarding not finding ft2build.h header when I tried to install matplotlib, what I l did to resolve the reported issue is :

我也在使用MacOs 10.8，在没有找到ft2build时遇到了同样的问题。h header当我尝试安装matplotlib时，我为解决报告的问题所做的是:

1) replacing "ft2build.h" in the following call within the file "setupext.py" :

1)取代“ft2build。h在文件“setupext”中的以下调用。py”:

                                 return self._check_for_pkg_config('freetype2', 
                                 'ft2build.h',
                                  min_version='2.4', 
                                  version=version)

by the complete path to the ft2build.h header, in my case :

通过ft2build的完整路径。h标头，在我的例子中:

                                return self._check_for_pkg_config('freetype2', 
                               '/usr/local/Cellar/freetype/2.5.2/include/freetype2/ft2build.h',
                                min_version='2.4', 
                                version=version)

I think, but have not tested, that the problem is solved in an upstream commit of matplotlib. Here is my reasons why:

我认为，这个问题在matplotlib的上游提交中得到了解决，但还没有经过测试。以下是我的理由:

I also had a similar issue, and fixed it in a reasonably straightforward way using homebrew.

我也有一个类似的问题，用自制的方法用一种相当简单的方式解决了这个问题。

You don't have to link the freetype libraries for this reason. The main problem is, after you install freetype using homebrew, you are told to add

由于这个原因，您不必链接*类型库。主要的问题是，在使用homebrew安装freetype之后，需要添加

-I/usr/local/opt/freetype/include

to your CPPFLAGS. However, this alone is not sufficient, and you also have to add the the freetype2 subfolder as well.

CPPFLAGS。但是，仅这一点是不够的，您还必须添加freetype2子文件夹。

So in order to install matplotlib, do this:

因此，为了安装matplotlib，请这样做:

brew install freetype
brew install libpng
LDFLAGS="-L/usr/local/opt/freetype/lib -L/usr/local/opt/libpng/lib" CPPFLAGS="-I/usr/local/opt/freetype/include -I/usr/local/opt/libpng/include -I/usr/local/opt/freetype/include/freetype2" pip install matplotlib

brew install freetype
