Error on "ng new ..." - unknown option `--silent'

[petdud]

Hi,

I am trying to create a new project with @angular/cli but it fails. Two days ago it was working with no issue and since that something broken and I can't figure what I did or why it does broken and there is nothing in Google regarding this issue. When creating new project with ng new projectname, it shows error right behind generating app.component.ts

error: unknown option `--silent'
Error: Package install failed, see above.
Package install failed, see above.

Here is the log:

However, if I cd into the app directory, run npm install, and then ng serve --open everything appears to be working just fine.

Is yarn configured as the default package manager for the CLI? If so the version of yarn is most likely outdated.

@clydin, thanks for the suggestion. That was it for me.
