Why doesn't Angular CLI project start?

Question

I have an Angular 4 project that I created a couple of months ago. When I go into the Angular project folder and type in ng serve, I get this error:

You have to be inside an angular-cli project in order to use the serve command.

Any idea what is wrong?

Is there some specific file that I can verify is there?

As a side note, I create a ng new Folder2 and was able to successfully run ng serve in that folder.

is your project built with angular cli ? if so, do you have file .angular-cli.json in a project folder? Otherwise you might be running the ng serve command from the wrong folder. — angularconsulting.au

.angular-cli.json is there. Going down another level (outside of the project) didn't help. — 4thSpace

did your .angular-cli.json has "apps": [ ] property declared and what is your cli version on a project? — angularconsulting.au

For me it is seems like as you didn't touch the project for so long you might have an older version of the angular cli in you project than your global version or way around.

if you run ng -v outside your project it show you global cli version
if you run ng -v inside your project it will show you local cli version, also you can check the cli version in package.json in devDependencies

So you have two options.
1 update angular cli
2 run npm run ng serve this way npm will run the local angular cli, the one form package.json file

Outside of the project folder: angular-cli: 1.0.0-beta.28.3, node: 8.0.0. Inside the project folder is the same but I also have this output: @angular/cli: 1.0.3, which is the same version coming from package.json.

angular-cli is an old package you need to get rid of this. then run` npm install @angular/cli -g` to install the latest version.

Running npm run serve throws this error: npm ERR! missing script: serve.
