Answer 1

I had that problem and I had to reinstall Angular Cli.

The way I reinstalled is by downgrading and then upgrading it back. I supposed you can also remove either the package from node_modules or doing npm uninstall @angular/cli and then npm i @angular/cli@1.7.4 .

The way that worked for me was doing this:

My version of npm (version 6.0) will downgrade angular cli if I install a different version $ npm i @angular/cli@1.7.3

Then I upgraded back to 1.7.4 $ npm i @angular/cli@1.7.4

Answer 2

The issue in my case was that I had files and nodes directories in the root directory. I remove it.

rm -rf node_modules/
rm package-lock.json
