Solution 1:

If the answer is always y:

yes | pip install <package>

Solution 2:

A silent install is possible by using the quiet flag:

pip install somepackage --quiet

yes | pip install somepackage --quiet

This truly has its mouth shut!

Adding an answer, since things have changes since 2011...

Pip version 1.1 release on 2012-02-16 has introduced a command line switch --exists-action <action> which allows to specify the default behavior from (s)witch, (i)gnore, (w)ipe, (b)ackup, (a)bort.

According to the current documentation pip can only prompt for information if --exists-action is unspecified.
