Phonegap no architecture issue when build

I am new to iPhone development and I use Phonegap since I know web development. I followed instruction in below sites: http://wiki.phonegap.com/w/page/16494778/Getting-Started-with-PhoneGap-%28iOS%29 https://github.c开发者_开发百科om/phonegap/phonegap-iphone/blob/master/README.md

But I got this error

No architectures to compile for (ARCHS=i386 ppc, VALID_ARCHS=armv6 armv7).

I already went to Project Setting and changed Base SDK to iPhone Device 3.1.3 but the problem is still there.

Any advice?

set the "valid archictectures" in Project Info

Had the same prob. If testing in the simulator: Click top left where you can choose the simulator and check if the top item "Device" is checked. If yes ckeck "Simulator" and try again.
