How I can connect tryton with with postgresql. Apart from that , I can't find configuration file of trytond

I see that you’re using trytond on Windows. I can only make educated guesses about this as I never did it myself.

Those are not errors, it’s just stating that the requirements for installing tryton are already satisfied.

You can specify the configuration file on the command line with the -c switch.
Otherwise it will look at file located at the content of the environment variable TRYTOND_CONFIG (no idea how to set that on windows).
