如何在ubuntu12.04中为cairo设置路径？

Question

我需要用python3.2+安装pycairo。但在系统中安装pycairo时出错

Downloading/unpacking git+http://anongit.freedesktop.org/git/pycairo (from -r requirements.txt (line 7))
  Cloning http://anongit.freedesktop.org/git/pycairo to /tmp/pip-ud145u-build
  Running setup.py egg_info for package from git+http://anongit.freedesktop.org/git/pycairo
    cairo >= 1.10.2  Failed
    Package cairo was not found in the pkg-config search path.
    Perhaps you should add the directory containing `cairo.pc'
    to the PKG_CONFIG_PATH environment variable
    No package 'cairo' found

    Complete output from command python setup.py egg_info:
    cairo >= 1.10.2  Failed

Package cairo was not found in the pkg-config search path.

Perhaps you should add the directory containing `cairo.pc'

to the PKG_CONFIG_PATH environment variable

首先安装libcairo2-dev：

sudo apt-get install libcairo2-dev
