i had the same problem:

Solutions is simple: Run the following commands one by one.

  1. sudo npm cache clean -f
  2. sudo npm install -g n
  3. sudo n stable

after that run the following command to create your new project.

ng new <projectName>

if still having problem then simply close the terminal and open again.

you are good to go !!!!

try this:

  sudo npm uninstall -g @angular/cli
  sudo npm cache clean --force
  sudo npm install --force -g @angular/cli

Worked for me!

Seems like your NodeJS version is not compatible with your Angular CLI version. See the Angular CLI/Angular/NodeJS/Typescript compatibility details here

Also I would recommend to use NVM to manage NodeJS - this way you can switch between NodeJS versions with ease.

You have not write permission to create directory, try it with :

sudo npm install -g @angular/cli
