NG SERVE命令问题

Question

I got problem with running my angular app via ng serve.

After hours and hours of fighting with angular (had many problems with angular cli) I am able to generate project without errors. I imported this project to IntelliJ and want to run by ng serve command.

after call ng serve got this: The program 'ng' is currently not installed. You can install it by typing: sudo apt install ng-common

Any ideas?

Answer 1

Make sure that you are running the "ng serve" command from inside the root directory of your angular project (the cli path is correct).

This error occurres because your command line interface cannot make sense of the command and whilst "ng new project" may execute from practically anywhere, other ng commands such as "ng serve" can only execute from within the project root directory.

Hope this guide will help you to create a project without errors.

1. first open terminal or console window and run, npm install -g @angular/cli
2. To create a new workspace and initial starter app, ng new my-app-name
3. Go to my-app-name folder, cd my-app-name
4. Launch the server by using the CLI command, ng serve --o (--o to open in browser)
