Repro steps

• ng new e-commerce-with-tut-ng4
• cd e-commerce-with-tut-ng-4
• ng serve (to test if works)

Observed behavior

After that I’ve got this ->

C:\Users\TheTanadu\Desktop\codetemp\e-commerce-with-tut-ng4>ng serve
module.js:471
    throw err;
    ^

    at tryModuleLoad (module.js:446:12)
    at Function.Module._load (module.js:438:3)

After all I came here but when I wanted to use ng --version in this path I’ve got same error like that what is up and I had to go cd … and then use ng -v

Desired behavior

I wanted to see local server

Mention any other details that might be useful (optional)

I struggled with the same problem just a minute ago. My project was generated using the v 1.6.0 of angular-cli.

1. npm update -g @angular/cli
2. editing my package.json changing the line “@angular/cli”: “1.6.0”, to “@angular/cli”: “^1.6.0”,
3. npm update did the trick.

Only need run 👍 : npm i -D @angular-devkit/core
