I tried to run following Angular project: https://github.com/MangeshPersonal/Observabledemo.git

Cloned it, cd into root folder and did ng serve. Got error:

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

    at Object.<anonymous> (/usr/local/lib/node_modules/@angular/cli/models/command-runner.js:87:23)

How to fix this error and make it work? What process should create this angular.json file? How to migrate this older project to a new version of angular?

I am using Angular CLI: 6.0.8 Node: 10.6.0.

Thanks.

It’s probably because your global @angular/cli , project @angular/cli version or @angular/compiler-cli doesn’t match.

Can you run the following command to verify that 

ng -v

If they don't match eg : 

"@angular/cli": "6.0.0-rc.3",
"@angular/compiler-cli": "^5.2.0",

Then you need to update or downgrade to match both of these.
