Question

When i install angular and try to use this command line : ng -vi got an error (check jpeg file) .. I have installed : node 6.10.3 someone have a solution

Answer 1

Those errors are caused by you manually stopped @angular/cli from installing packages into your project folder.(When running ng -v in a angular/cli project folder, angular/cli will trying to output your version information of installed @angular/xxx packages).

mention that when you pressed Ctrl + C , the task will stop even you pressed N later.

Solution:

run npm install at your project folder and wait for it to be finished, then when you run ng -v again, the errors will gone.
