Compiling mysql-python on Windows with PIP

Question

So I have Python 2.7 and setuptools installed on my Windows 7 laptop. I also have Visual Studio 2008 Express installed and MySQL with dev tools.

I am trying to install mysql-python via pip like:

pip install mysql-python

I am getting link errors:

I had the same problem and exact same errors.I don't know why but

pip install Mysql-python

gave errors. But when I tried

easy_install Mysql-python

It worked.I don't know why but it did work but would love to know why.
