Sounds like missing dependencies. Try removing node_modules and running npm install again.

  • Open command prompt and go in your project directory. Then run npm install

I was facing same issue, I had run ng unit in system root directory by mistake. Once I had delete all the angular-cli files it was working

What I had done to resolve on windows-10 system.

  1. Open cmd.
  2. Run dir. (in Linux or mac its ls).
  3. If you find angular-cli files just delete.

And it's work for me.

This works for me on 1.3.1. I also change the dev in the package from angular/cli 131 to angular cli 1.7.4 (may be optional)

Verify that you own the directory (chown groupe:user directory on ubuntu) and try root launch for the ng (sudo)

or / and remove the node dir and -lock.json, run npm i and launch or sudo launch ng

I know now that u need too own the rights on the directory not to have problem with sudo and install permissions. u won't need sudo. look at npm update also.

chown user:user /directory -> 4 ubuntu
