I updated to the latest node v9.1.0 and now npm doesn\'t work.
npm WARN npm npm does not support Node.js v9.1.0
If you are getting the same warnings while creating or importing an Angular project in an IDE such as Eclipse ,do the following:
File->New->Angular In the window that appears change the versions of Nodejs and NPM to "use system installation"
... If the process crashes at "installing packages for tooling via npm"
Close the terminal in IDE and manually go to the project directory and do "npm install".
Refresh the project in IDE
