问题：使用virtualenv进行pip安装Matplotlib错误

我正在尝试在新的virtualenv中安装matplotlib。

当我做： 

pip install matplotlib

要么

pip install http://sourceforge.net/projects/matplotlib/files/matplotlib/matplotlib-1.1.0/matplotlib-1.1.0.tar.gz

我收到此错误：

building 'matplotlib._png' extension

gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall -fPIC -  DPY_ARRAY_UNIQUE_SYMBOL=MPL_ARRAY_API -DPYCXX_ISO_CPP_LIB=1 -I/usr/local/include -I/usr/include -I. -I/home/sam/django-projects/datazone/local/lib/python2.7/site-packages/numpy/core/include -I. -I/usr/include/python2.7 -c src/_png.cpp -o build/temp.linux-x86_64-2.7/src/_png.o

src/_png.cpp:10:20: fatal error: png.h: No such file or directory

compilation terminated.

error: command 'gcc' failed with exit status 1

有人知道发生了什么吗？

任何帮助，不胜感激。

Anyone have an idea what is going on?

Any help much appreciated.

构建Matplotlib需要libpng（freetype以及）不是python库，因此pip无法处理（或freetype）安装它。

您需要按照libpng-devel和freetype-devel（或与您的操作系统等效的其他方式）安装一些东西。

请参阅matplotlib 的构建要求/说明。

点击查看英文原文

Building Matplotlib requires libpng (and freetype, as well) which isn’t a python library, so pip doesn’t handle installing it (or freetype).

You’ll need to install something along the lines of libpng-devel and freetype-devel (or whatever the equivalent is for your OS).

See the building requirements/instructions for matplotlib.

要生成png格式的图形，您需要安装以下依赖包

sudo apt-get install libpng-dev
sudo apt-get install libfreetype6-dev

Ubuntu https://apps.ubuntu.com/cat/applications/libpng12-0/ 或使用以下命令

sudo apt-get install libpng12-0

To generate graph in png format you need to Install following dependent packages

由于我两次都在这个问题上苦苦挣扎（即使在全新安装kubuntu 15.04之后），而安装freetype也解决不了任何问题，因此我进行了进一步调查。

解决方案：
来自github问题：

仅当未安装pkg-config时，才会发生此错误；
现在，简单的操作
sudo apt-get install pkg-config
将支持包含路径。

安装完成后顺利进行。

As I have struggled with this issue twice (even after fresh kubuntu 15.04 install) and installing freetype did not solve anything, I investigated further.

The solution:
From github issue:

This bug only occurs if pkg-config is not installed;
a simple
sudo apt-get install pkg-config
will shore up the include paths for now.

After this installation proceeds smoothly.

在OSX上，我可以通过以下方式安装matplotlib：

pip install matplotlib==1.4.0

只有在我跑完之后：

brew install freetype

On OSX I was able to get matplotlib to install via:

pip install matplotlib==1.4.0

only after I ran:

brew install freetype

如果在MacOSx上尝试

xcode-select --install

这符合subprocess 32，失败的原因。

If on MacOSx try

xcode-select --install

This complies subprocess 32, the reason for the failure.
