Thanks @JanStureNielsen.

Error fixed through below commands.
-npm install -g angular@latest
-npm install -g is-my-json-valid

[kbradl16]

This was a pain to figure out, so here is my solution

1. npm install -g angular@latest

2. Make sure the ng path is correct

   • cd ~/npm-global/bin
   • ls and make sure ng exists

3. create .bashrc file on your home directory

   • touch ~/.bashrc
   • vim ~/.bashrc

4. Add ng as alias

   • press a (enables edit mode) then type in the following
   • alias ng="~/npm-global/bin/ng"
   • press esc (to get out of edit mode) then :wq (in vim will save)

5. Temporarily Update .bashrc reference
   Your terminal wont take bash updates until a restart but the following command will let you use the updates during the terminal session:

   • source ~/.bashrc

6. Check that ng works

   • ng --version

Hope that helps someone!
