The root problem here is that a project cannot be determined. You can either change the current working directory using (cd) or provide the name of the project using the --project option.

We should update the error message to be more actionable.

This error occurs even when i executed ng g component in the root directory of the project. I have no idea how the cli determine the current project, but i don't think is only things about the error message

Can you please share you angular.json? You can option the architect sections if you'd like.

@alan-agius4 You can see my angular.json below

The problem here is that your projects are misconfigured in the angular.json. You have two projects in the same directory as the root is configured the same, as such the CLI cannot determine which project you intend to use.

     "blog-admin": {
            "projectType": "application",
            "root": "",
            "sourceRoot": "src",
    },
    "blog-admin-e2e": {
         "root": "",
         "sourceRoot": "",

After I changed blog-admin-e2e.root to e2e, things worked, thanks for help
