Question

first i am in the correct directory

I tried to ng serve which worked eariler today but now I get the following errors:

Local workspace file ('angular.json') could not be found.
Error: Local workspace file ('angular.json') could not be found.

then I ran ng update @angluar/cli --migrate-only --from 1.7.4

I did that by following the first answer from this stack overflow post: Error: Local workspace file ('angular.json') could not be found

the error from the update:

whats werid is I have no idea how to fix this.

update:

I deleted package-lock.json and then ran npm install then tried ng serve I then got the same error as before that my configuration has changed and that I have to run ng update.

ran ng update and got the same error as above.

attempted this fix:

npm install --save-dev @angular/cli@v6.0.0-rc.4
ng update @angular/cli --migrate-only --from=1.7.4

then got this error:

Answer 1

When the asker says

first i am in the correct directory

... that was my issue.

You should be running ng test in your angular directory.
If your project has several directories, make sure to go to the correct directory before running the tests.

Answer 2

It worked for me with just

ng update @angular/cli

Answer 3

I had the same problem Would you try as follows :

npm install -g angular-universal-pwa@beta
ng new --collection angular-universal-pwa myAwesomeApp
cd myAwesomeApp
npm start
