I know that this question already was on Stackoverflow, and I'm sorry for it, but I didn't get my right answer, so this is a situation: I try to run my project and I get this error --

The serve command requires to be run in an Angular project, but a project definition could not be found.

  1. Project was cloned from git and it is of elder vervion of Angular5.
  2. I tried to -npm install , -npm update, -ng i @angular/cli.
  3. Tried to unistall and clean cache.
  4. I -ng serve it in the right directory

So what I can do more to solve this issue???

    Are you trying to run ng serve and npm install commands from the project directory folder?

Try these,

  1. If you are running any commands like npm install or ng serve, always ensure that you are running them from the project‘s root directory. Eg: where your package.json & angular.json files are located.

  2. If you find a file named angular-cli.json instead of angular.json, you need to run this command,

    ng update @angular/cli --migrate-only --from=your_older_angular_cli_version_here

    For example if your older Angular CLI version is 1.0.0, 

    ng update @angular/cli --migrate-only --from=1.0.0

  3. If the above fixes didn’t help, Try this command,

    ng update --all --force
