    Reset to default 5

    Check in your package.json to see if you have this package in your devDependencies section or not

    "devDependencies": {
    "@angular-devkit/build-angular": "~0.803.18"
}

    If exist try to

    delete package-lock.json or yarn-lock.json

    run 

    npm cache clean --force

    then run 

    npm i

    This error (Unhandled exception for a module) occurs when node_modules folder does not exist inside the project, or when the folder exists, but does not contain all the dependencies downloaded.

    $ npm install mand will download all the dependencies into the node_modules folder of the proejct.

    npm install is automatically triggered in the background by the 'ng new', at the time of creation of the angular project.

    The other angular mands like 'ng build' or 'ng serve' mands assume that 'ng new' had pleted successfully.

    If, for some reason, the npm install failed at the time of creation, or if the node_modules folder got deleted after the project was created, then the other angular mands (ng serve, ng build, ...) will generate this 'Unhandled Exception'.

    Manually executing the npm install mand inside the project will download the dependencies and fix the issue.

    Install @angular-devkit/build-angular as dev dependency.

    npm install --save-dev @angular-devkit/build-angular

    or,

    yarn add @angular-devkit/build-angular --dev

    try this

    npm install --save-dev @angular-devkit/build-angular

    Make sure "@angular-devkit/build-angular": "~0.10.0" is available in devDependencies of package.json before running npm install in your angular root directory.
