- D. npm install -g vuecli
Remarks:
Explanation:
Vue CLI can be installed using the following command:
npm install -g @vue/cli
Explanation:
Vue CLI (Command Line Interface) is a full-featured tool for developing Vue JS applications. It provides a user-friendly command-line interface that allows developers to quickly set up a new Vue JS project, scaffold components, and manage dependencies.
To install Vue CLI, we need to use the Node Package Manager (npm) command npm install -g @vue/cli. The -g flag installs the package globally, so we can access the Vue CLI command from anywhere in the system.
Option A (npm install -g vue-cli) is incorrect because vue-cli has been deprecated since version 3.0.0 of Vue CLI, and it is no longer recommended to install Vue CLI using this command.
Option B (npm install -g vue) is incorrect because it only installs the Vue JS library, and not the Vue CLI tool.
Option D (npm install -g vuecli) is incorrect because it is not a valid npm package name.
