Angular CLI is installed globally on a Windows machine, which means it's available for use in any project.
This installation location is typically found in the user's AppData/Local/Programs/ nodejs/node_modules/@angular/cli directory.
Installing Angular CLI
Installing Angular CLI involves using the Command Prompt with administrator privileges. Run the command `npm install @angular/cli@17` to download and install the Angular CLI package and its dependencies from the npm registry.
This command installs the CLI globally on your system, making it available from any directory in the Command Prompt. It also sets up necessary files and configurations for Angular development.
The installation process may take a few minutes, depending on your internet connection and system performance. You'll see a progress bar and some output in the Command Prompt as the installation proceeds.
To verify whether Angular CLI is installed, you can check if the `ng` command is available. This command is provided by the Angular CLI, and you can use it to create and manage Angular projects.

The `ng` command can be used from any directory in the Command Prompt, thanks to the global installation of the Angular CLI. This makes it easy to work with Angular projects across multiple directories.
Here are the key components of the installation command:
- `npm install`: tells npm to download and install a package.
- `g`: installs the package globally, not just for a specific project.
- `@angular/cli`: specifies the package name, which is the Angular CLI.
- `@17`: specifies version 17 of the Angular CLI, but you can omit this to install the latest version.
Configuring the Environment
Angular CLI can be installed on a Windows machine using npm, which is the default package manager for Node.js.
The installation process requires a stable version of Node.js, as specified in the "System Requirements" section, which states that Node.js version 14 or higher is recommended.
You can check your Node.js version by running the command `node -v` in the command prompt, which should display the version number.
To install Angular CLI, you need to run the command `npm install -g @angular/cli` in the command prompt, as mentioned in the "Installation" section.
After installation, you can verify that Angular CLI is installed correctly by running the command `ng --version`, which should display the version number of Angular CLI.
The `ng` command is the primary command for Angular CLI, and it can be used to create new projects, generate code, and perform other tasks, as explained in the "Usage" section.
