Hi @rajeshwar-fissionhq, not sure what would cause this. What version of node/npm are you using?

node -v
v8.12.0
npm -v
6.4.1

hmm, that's probably not the issue. Could you paste the output of the following commands?
npm bin
and
ls -1 ./node_modules/.bin/

I Have the same issue, here is my npm bin :

/Users/MyUser/Projects/rest-hapi/node_modules/.bin

and ls -1 ./node_modules/.bin/ :

There is no rest-hapi-cli

hi @launay12u,

npm bin and ./node_modules/.bin/rest-hapi-cli seed should be performed within the directory for the project using rest-hapi (such as rest-hapi-demo), not rest-hapi itself.

I just ran into the same problem, using Webstorm to checkout the projet.
I reinstalled Node, npm but it didn't help.

Eventually, I ran the commands (git clone, npm install, ...) via command line, and it worked.

@JeanReneRobin glad you worked it out! Hopefully this will help others as I'm still unsure what is causing the issue.
