Look at the ng (github.com/angular/angular-cli/wiki) CLI Wiki. ng run is like execute something, not run my app. ng serve or ng run <appname>:serve seems like what you were trying. Some syntax changed a little in 6. — Jason Alexander

Use:

ng serve

See angular CLI docs - https://github.com/angular/angular-cli/wiki

Btw 'ng serve' is to run a dev server, but npm run build is to compile and publish a build.

Yeah that's right, the ng serve -o really saves, but depends on project configurations. npm start can work as well.

Double check command line syntax. This error can show if ng used instead of npm like when using package.json shortcut scripts.

npm run debug   (Correct) -- npm run the "debug" script
ng run debug    (Error)

What are the options other than debug?

SushiGuy Over a year ago

@justin.m.chase programmer choice. start is a common one. For example my package.json has "scripts": { "start": "ng serve --host my.website.com --port 443 -o" }. So typing npm run start is simply saying "run my 'start' script".

Check out the cli documentation.

I believe you need to specify your project's name in the build command.

ng build [project]

Also you can do the production build with the following command.

ng build [project] --prod

thanks both your example working fine now. But i still get same error on run. eg "ng run [project]"

bodorgergely Over a year ago

@MUHIUDDIN There is an issue on github in the angular-cli repo about not showing enough information to the user about this very same error message. Check it out: github.com/angular/angular-cli/issues/10955

bodorgergely Over a year ago

@MUHIUDDIN for the run command try this: ng run needs a target in the format of project:target and is erroring out because of that.

had this after upgrading to angular 6.

appears like the CLI command has changed to :

ng build --configuration <environment-name>

the migration from 5 to 6 also created a new "angular.json" file which now contains all the different configurations and their names.

Update angular.json file. Add defaultProject property (value will be the name of the desired project)

In Angular version 6, the build command is changed. Changing "build": "ng build --target=production --aot=true" to "build": "ng build --prod --aot" in package.json worked for me.

I had a similar problem after cloning the project from my repository on another machine. I used the commands:

$ npm link

$ ng serve

I had a similar problem after update the project from main branch.

I used the command: npm install

If node requires a minimum Node.js version >= v14.15.

sudo npm cache clean -f /
sudo npm install -g n /
sudo n stable /

For changing node versions

nvm install v16.10.         # Install v16.10.
nvm use v16.10.             # Use v16.10.
