I am getting this error message continuously:
Node packages may not be installed. Try installing with 'npm install'. Could not find the '@angular-devkit/build-angular:dev-server' builder's node package.
I did the following things to solve this
npm install
npm start
and some more instructions saw in stack overflow
Kindly help me, thanks in advance
Look like the package is used in module but not defined in the package.json file
So, only you have to do is that install the missing dependencies
npm i @angular-devkit/build-angular:dev-server --save-dev
I hope that's clear
