Angular is a popular JavaScript framework for building single-page applications, and the Angular CLI (Command Line Interface) is a tool used to create, build, and serve Angular projects. In some cases, you may need to install a specific version of Angular using the Angular CLI. This tutorial will guide you through the process of installing specific versions of Angular with Angular CLI.
Understanding Angular and Angular CLI Versions
Before we dive into the installation process, it’s essential to understand the relationship between Angular and Angular CLI versions. The Angular CLI version determines the version of Angular that will be installed in your project. Each Angular CLI version is designed to work with a specific range of Angular versions.
Installing a Specific Version of Angular CLI
To install a specific version of Angular, you need to install the corresponding version of Angular CLI. You can do this using npm (Node Package Manager) by running the following command:
npm install -g @angular/cli@<version>
Replace <version> with the desired version of Angular CLI. For example, if you want to install Angular CLI version 10, run:
npm install -g @angular/cli@10
Creating a New Project with a Specific Version of Angular
Once you have installed the specific version of Angular CLI, you can create a new project using the following command:
ng new <project-name>
Replace <project-name> with the name of your project. The resulting project will be created with the specified version of Angular.
Alternative Method: Using npx
You can also use npx (a package runner tool) to create a new project with a specific version of Angular without installing the Angular CLI globally:
npx @angular/cli@<version> new <project-name>
Replace <version> with the desired version of Angular CLI and <project-name> with the name of your project.
Verifying the Installed Version
To verify that the correct version of Angular has been installed, check the package.json file in your project directory. The file should contain the specified version of Angular.
Compatibility Matrix
While there is no official compatibility matrix for Angular and Angular CLI versions, you can refer to the Angular CLI repository on GitHub to determine which version of Angular corresponds to a specific version of Angular CLI.
By following these steps, you can install specific versions of Angular using the Angular CLI. Remember to always check the compatibility matrix and verify the installed version to ensure that your project is set up correctly.
