           sudo rm -rf  /usr/local/lib/node_modules/npm/
           sudo rm -rf  /usr/local/lib/node_modules/@angular/

After removed npm, node, angularcli.


Now, Install Node with different version using NVM

  1. sudo apt-get install build-essential libssl-dev
  2. curl -sL https://raw.githubusercontent.com/creationix/nvm/v0.33.8/install.sh -o install_nvm.sh
  3. nano install_nvm.sh
  4. bash install_nvm.sh
  5. source ~/.profile
  6. nvm ls-remote (List of all Node versions)
  7. nvm install <version number> (example: nvm install 8.11.3)
  8. nvm use 8.11.3 (After install multiple version of node, we can set needed version.)
  9. nvm alias default 8.11.3 (we want to set node version as default.)
  10. nvm use default
  11. nvm help (Help)

Next, Install @angular/cli on specific node version.

  1. npm install -g @angular/cli (Install latest version of @angular/cli)
  2. npm install -g @angular/cli@1.4.10 (Install specific version of @angular/cli)
