SharePoint framework– “Syntax error: Unexpected token = ” for Yeoman SharePoint Generator

When I executed “yo @microsoft/sharepoint” to generate a SharePoint extension, I got following error message

Attempt - 01

First I tried to uninstall and install SharePoint Framework Yeoman generator by executing following command

npm uninstall -g generator-@microsoft/generator-sharepoint

npm install -g @microsoft/generator-sharepoint

This could not resolve the issue

Attempt - 02

Tried uninstalling and installing both Gulp and Yeoman using following commands

npm uninstall -g gulp

npm uninstall –g yeoman

npm install -g yo gulp

Still the issue persisted

Attempt – 03 (Success!!)

• Uninstall Gulp and yeoman

npm uninstall -g gulp

npm uninstall –g yeoman

• Uninstall NodeJs
• Install NodeJS v6.11.5
• Install Gulp and Yeoman

npm install -g yo gulp

That’s it.
