Hi,
I’m completely lost. I can not install ionic.
When I do : C:\Travail\AppIonic>npm install - g cordova ionic
I obtain :
C:\Travail\AppIonic\Meteobourse>npm install - g cordova ionic
npm ERR! addLocal Could not install C:\Travail\AppIonic\Meteobourse-

I have try to upgrade node in v7.2.0. But the problem is same.
I have try to upgrade npm in v4.0.3. But the problem is same too 
What can I do ? Thank you for your help
Use the stable LTS of Nodejs, which I think is 6.9.1. Once you have that, install npm 3.10.10. Then clean your npm cache. Then you should be ok. Don’t mess with Node 7 or npm 4 yet. They are new, there are known issues, and npm 4 in particular introduces breaking changes to a lot of builds.
Thanks a lot for your help. I did everything as requested but here is what I get:
C:\Travail\AppIonic>npm install -g cordova ionic

And if I try to run the programm with “ionic serve” I get:
Caught exception:

Mind letting us know? https://github.com/driftyco/ionic-cli/issues
Those warnings are not a big deal. It looks as though your ionic installed “fine.” But if you are having that module error when trying to ionic serve one of the starting templates, then you might have something left over from the old bad install. Uninstall everything, making sure that npm’s node-modules folder is gone. (I once had to physically drop one in the trash when upgrading from one beta to another.) Then reinstall from scratch, starting with Nodejs.
It’s working !!!
Thanks a lot
To help beginners like me, here are the commands to uninstall Codova and ionic:
npm uninstall -g ionic
npm uninstall -g cordova
