npm install -g @sencha/ext-gen
ext-gen app -a

Any update on this? Still giving the same error with 6.7

I solved it by patching ext-gen script with an extra line of code. Here are the details: https://stackoverflow.com/questions/54724299/unhandledpromiserejectionwarning-error-cannot-find-module-using-ext-gen/56316813#56316813
