I cannot reproduce the issue, I tried with node 6.9.5/npm 3.10.0, node 7.8.0/npm 4.2.0 and node 7.9.0/npm 4.2.0. I'm on latest OSX version.

Did you install a RC/beta version of angular-cli? According to this post: angular/angular-cli#4736
the issue is related to either a missing .angular-cli.json or outdated npm package that may come from the cache.

Could you try this and see if it resolves the issue?

npm uninstall -g angular-cli
npm uninstall -g @angular/cli
npm cache clean
rm -rf node_modules
npm install

Already I had done this, Anyway redo and nothing changed !

[sinedied]

Are you sure there is an .angular-cli.json in the folder? Did you move the files after cloning?

The debug log you provided shows something strange, it says node v7.8.0 but from the bin path the node version seems to be 5.3.0: /usr/local/Cellar/node/5.3.0/bin/node`

What does it says when you type which node?

[sr-hosseyni]

Sorry it was my bad. I had moved files after clone but forgot to move hidden files !
Thank u so much
Your answer

Did you move the files after cloning ?

was great

[xlabpoh]

How to move the hidden files? Example?

[sinedied]

@xlabpoh Move the parent folder instead, or use mv source/.* dest/
