I updated to the latest version of AngularCLI and now, whenever I try to run ng inside an Angular Project generated using Angular CLI, it's giving me this error:

Repro steps.

I just tried to uninstall and reinstall Angular CLI using the following commands:

npm uninstall -g @angular/cli
npm cache clean
npm install -g @angular/cli@latest

I would like to emphasize on the fact that it's working as expected in a folders outside the ones generated by Angular CLI.

The log given by the failure.

Can you try reinstalling in your local projects?
Ideally upgrading your local project to the latest version as well, and then retrying.

Thanks!

[SiddAjmera]

@Brocco , I created the project after uninstalling and reinstalling AngularCLI. So ideally my project should have the same version as my global version which is the latest version. Please do correct me if I'm wrong.

Thanks!

Check path C:\USERS{Computer-name}
I had same issue. went as far as re-installing node. But what fixed it for me was deleting a ".angular-cli.json" file i found in that directory

Are you still able to reproduce this issue with the latest version?
