Angular project error with ng serve Cannot find module '@ angular-devkit / core'

Question

I have the global version 1.5.0 of angular / cli, I have downloaded the visual studio code and I have created a project with the command "ng new projectCheckBox", then I have done an ng serve and visual studio code throws me the following error

E: \ Projects \ AngularCode \ projectCheckBox> ng serve
module.js: 487
 throw err;
 ^

Error: Cannot find module '@ angular-devkit / core'
 at Function.Module._resolveFilename (module.js: 485: 15)

I'm missing something?

Are you using Node Package Manager? If so, you might wanna run:

npm install

(to install all missing packages) or

npm update -g @angular/cli

(to update your cli (globally))

Lea is right! Can use this :

npm update -g @angular/cli

and edit your package.json changing the line "@angular/cli": "1.5.0", to "@angular/cli": "^1.5.0",

after use :

npm update

But command : npm update -g @angular/cli should be enough :) .
