Updating Angular CLI If you're using Angular CLI 1.0.0-beta.28 or less, you need to uninstall angular-cli package. It should be done due to changing of package's name and scope from angular-cli to @angular/cli : npm uninstall -g angular-cli npm uninstall --save-dev angular-cli To update Angular CLI to a new version, you must update both the global package and your project's local package. Global package: npm uninstall -g @angular/cli npm cache clean # if npm version is > 5 then use `npm cache verify` to avoid errors (or to avoid using --force) npm install -g @angular/cli@latest Local project package: rm -rf node_modules dist # use rmdir /S/Q node_modules dist in Windows Command Prompt; use rm -r -fo node_modules,dist in Windows PowerShell npm install --save-dev @angular/cli@latest npm install Sources: https://github.com/angular/angular-cli#updating-angular-cli
