Answer 1

I met the problem when my devDependencies is Angular 7
but install angular/cli of version 8.x.x

"devDependencies": {
    "@angular-devkit/build-angular": "^0.13.8",
    "@angular/cli": "^7.3.8",
    "@angular/compiler-cli": "^7.2.12",
}

just remove the cli globally

npm unintsall -g @angular/cli
npm cache clean -f 

check the state

ng version # if remove successfully, the command would no work

then install cli again

sudo npm install @angular/cli@^7.3.8 -g
