Problem In Running easy_install.exe under Windows

I am running Python under windows.

I face no problem in installing pysqlite package.

Is there other alternative?

Thanks!

The psycopg PyPi posting does not contain a pre-built w32 installer that easy_install can use nor could it find a way to build from source.

Here are some pre-built versions of the psycopg module.

easy_install only knows how to install modules distributed with the Python standard distribution and packaging solution called distutils. Psycopg is not. Psycopg is instead installed with the so called CMMI dance: configure/make/make install. Doing that on Windows is tricky, hence, you need to download a precompiled version, see Christians answer.
