I am running into an error after starting up a new project, which causes me to wonder whether I'm correctly reading the information I got online. Following instructions from Angular and other sources about using Yarn as the packkage manager, I ran these commands: npm install -g @angular/cli typescript less less-plugin-clean-css ng version ng config -g cli.packageManager yarn ng new my-app yarn add @angular/material @angular/cdk yarn install ng serve At this point, after confirming that the Angular version was indeed the one I wanted, I thought the app generated by the Angular CLI would simply run. However, I get this error message: Node packages may not be installed. Try installing with 'yarn install'. Error: Could not find the '@angular-devkit/build-angular:dev-server' builder's node package. Having already run the suggested command, I went back to the Yarn documentation to double check the meaning of the command. I am now wondering whether yarn's installation of the packages is compatible with what Angular expects. I am surprised to find very little information about this. Just about every search result speaks of installing packages with npm install. If so, I wonder what's the point of using yarn. I am clearly missing something to understand how Angular 19 is supposed to work with Yarn. The .angular-config.json file in my home directory has this: { "$schema": "./node_modules/@angular/cli/lib/config/schema.json", "cli": { "packageManager": "yarn", "analytics": false }, "version": 1, "projects": {} } Continue reading...
