How to let the python in cygwin use the package installed in windows?

I installed python on both cygwin and windows. However, there is no package installed in cygwin's site-packages. Here the directory is /usr/lib/python2.7/site-packages. In contrast, they are all installed in C:\Python\Lib\site-packages. Since I installed the packages in C:\Python\Lib\site-packages, pip in cygwin will skip the installation of those packages. Is there a method I directly use the packages in windows?

First, make sure (in cygwin bash) that python2 and/or python3 is/are ahead of the windows versions of the programs in your path. As of this writing, python 2, if installed, can be called aspython or python2, while python 3 is called python3. This may change as more Linux distributions switch to using python 3 as the default. Use python -V or python3 -V to verify that you get the cygwin version of python when running bash. (I no long install python 2.)

$ which python
which: no python in (**"your path"**)
$ which python3
/usr/bin/python3
$ python3 -V
Python 3.6.4

Then verify that you can run the appropriate version of pip for your python. To be absolutely sure of which version you are using, run

$ python3 -m pip --version
pip 9.0.1 from /usr/lib/python3.6/site-packages (python 3.6)

Now you should be able to install most packages from PiPI by replacing pip or pip3 with python -m pip or python3 -m pip.

If you try to install a package that requires compilation, i.e, one that is distributed as a binary package on windows, you will need to have the gcc compiler tool chain, and possibly the python-devel or python3-devel package. BTW, always use the latest cygwin setup program from cygwin.com. You may also need to install any required cygwin packages using setup before the package will install.
