Question

I want to create an angular 2 App with angular cli

I have written in the cmd:

npm install angular-cli -g

then:

ng firstngapp

but it show me an error when I write npm start !

I don't understand the problem

Answer 1

Below steps worked for me:

Delete node_modules folder and package-lock.json file. npm install ng serve

Answer 2

i got the same issue, and the reason is

1. when you run ng new app-name it will create a new directory with app name and install everything in that.
2. after running the above command, human tendency is to run ng serve and because your app is in sub directory it will not find package.json and throw the mentioned error.

Solution is pretty simple. just move to the sub directory and then run ng serve

Answer 3

You create new project with:

ng new firstngapp

In your example you are missing new. This would create folder, generate files and run npm install for you. It seems that you've created folder but there's no Angular CLI app in it.

And for starting the app use:

ng serve

npm start is only used if you have ejected from cli.

Answer 4

Try to run

npm install

in the project folder

Answer 5

May help you.

• Delete All folders you have created previously
• Create fresh folder
• Then try navigate to that folder from command "cd foldername"
• then try to install "npm install"

This will solve you problem.

Answer 6

**You should be in the newly created YOUR_APP folder before you hit the ng serve command **

Lets start from fresh,

1) install npm

2) create a new angular app ( ng new <YOUR_APP_NAME> )

3) go to app folder (cd YOUR_APP_NAME)

4) ng serve

I hope it will resolve the issue.
