I updated the Angular CLI to the latest @angular/cli@7.0.2 on a Mac OS. When issuing the command ng new testng7, I get this error:

Schematic input does not validate against the Schema: {"name":"testng7"}
Errors:
  Data path "" should have required property 'version'.

And nothing is created. Any clues how to fix?

This error is possible of avoiding naming standards

Project name can not have underscore '_'. It can have dashes '-', small and capital letters and digits.

Valid Project Names

myProject //camel casing style or JavaScript style

MyProject //normal style

MyProject1 //letters and numbers mixed style

My-Project1 //letters, numbers and dash mixed style

Invalid Project Names

MyProject-1 //dash can not be between letter and digit

My_Project //underscore is restricted

I added this flag to make it work --client-project

ng add @nguniversal/express-engine --client-project=launcher

First, to upgrade, I did this:

npm i -g @angular/cli
npm i @angular/cli

to install globally and locally. Running an npm audit fix revealed there is a problem with a missing package.json in the npm logs - missing from my root directory! So I created one with the following command in my home directory:

npm init --yes

for a default one. Now issuing an ng new projName works.

I was having the same problem

Schematic input does not validate against the Schema: {"name":"DemoProj"}

Errors:

Data path "" should have required property 'version'.

do the following steps to resolve this issue

1) uninstall -g angular-cli

2) npm uninstall --save-dev angular-cli

3) npm install -g @angular/cli@latest

4) npm install --save-dev @angular/cli@latest

5) npm install -g

6) ng new YourProjectName

i hope it will work

Try the

ng new projectName

cmd in powershell with admin rights. I did it once and after that it works in normal cmd promt too.

none of the solutions helped me or does not deal with the root cause. I found this in my angular.json

  "schematics": {
"@schematics/angular:component": {
  "styleext": "scss"
 }
}

Also my IDE was showing styletext property was not allowed. So I changed the above to this and it works.

    "@schematics/angular:component": {
      "skipTests": true
    }
  }

Sometimes can be caused by wrong 'global' version of ng.

Try

npx ng generate component MyComponent

That will use 'local' ng installed into node_modules of project
