我需要用 python3.2+ 安装 pycairo。但是在我的系统中安装 pycairo 时出现错误,
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:
