I was trying to install yeoman. But I met following errors.
C:\Users\xxxxx>npm install -g yo

nd is now out of date with respect to npm

Then I tried to 'npm install -g yeoman-doctor' to bypass this error. After yeoman-doctor was installed, the yodoctor can be found like below.
C:\Users\xxxx>yodoctor
Yeoman Doctor

But unfortunately, the issue still happen when I re-tried to 'npm install -g yo'.
Could you tell me the workaround? thanks .
The error show your npm was outdated. What you need is update your npm first.
Try
npm -g update
or
npm -g install npm
