我已从此web-page下载了pycairo，并尝试使用pip进行安装：
pip install pycairo-1.10.0-cp27-cp27m-win_amd64.whl
返回了：
pycairo-1.10.0-cp27-cp27m-win_amd64.whl is not a supported wheel on this platform.
Storing debug log for failure in C:\Users\user\pip\pip.log
pip.log显示了这一点：
------------------------------------------------------------
C:\Python27\Scripts\pip run on 11/05/16 10:46:49
pycairo-1.10.0-cp27-cp27m-win_amd64.whl is not a supported wheel on this platform.
Exception information:

UnsupportedWheel: pycairo-1.10.0-cp27-cp27m-win_amd64.whl is not a supported wheel on this platform.
我使用以下方法检查了支持的pip标签：
import pip
print pip.pep425tags.get_supported()
输出结果为：
[('cp27', 'none', 'win_amd64'), ('cp27', 'none', 'any'), ('cp2', 'none', 'any'), ('cp26', 'none', 'any'), ('cp25', 'none', 'any'), ('cp24', 'none', 'any'), ('cp23', 'none', 'any'), ('cp22', 'none', 'any'), ('cp21', 'none', 'any'), ('cp20','none', 'any'), ('py27', 'none', 'any'), ('py2', 'none', 'any'), ('py26', 'none', 'any'), ('py25', 'none', 'any'), ('py24', 'none', 'any'), ('py23', 'none', 'any'), ('py22', 'none', 'any'), ('py21', 'none', 'any'), ('py20', 'none', 'any')]
由于('cp27', 'none', 'win_amd64')列在那里，我希望安装pycairo-1.10.0-cp27-cp27m-win_amd64.whl没问题，但我不能。还有什么我想念的吗？
