Error installing RPy2-2.3.8 on Windows 7, Python 3.3

Question

guys. I'am trying to installing RPy2-2.3.8 on Windows 7 (64bit), Python 3.3, but RPy2 seems to have quite a lot of installation problems...:(

I tried to install RPy2 by typing "python.exe setup.py install" on "cmd" on windows environment.

R version 3.0.2 was successfully installed and the path of it was added on environment variable.

However, the following error occurred. Can anybody tell what does this error mean?

**D:\>cd rpy2-2.3.8**

D:\rpy2-2.3.8>c:\Python33\python.exe setup.py install

For me it's especially weird because the error is "TypeError." Plus, what does all the warnings mean?

All kinds of discussion will be appreciated.

Many thanks.

RPy does not support Python 3.x. You have to use 2.5 <= Python < 3.0. See official documentation for details.
