Closed 1 year ago.
I have just installed latest versions of Node.js (v14.16.1) and Angular (11.2).
Our TA gave us Angular project, but I cannot ng sever-it on my machine. I get following error:
An unhandled exception occurred: No projects support the 'serve' target.
See "C:\Users\Miljan\AppData\Local\Temp\ng-hVo6jS\angular-errors.log" for further details.
When I open the angular-errors.log, I have following output:
[error] Error: No projects support the 'serve' target.
