How to Install Angular CLI with Specific Version? Look no further! In this article, we will provide you with a detailed and comprehensive guide on how to install Angular CLI with the version of your choice. Whether you are a beginner or an experienced developer, this step-by-step guide will help you get started with Angular CLI in no time.
Angular CLI (Command Line Interface) is a powerful tool that allows developers to create, manage, and deploy Angular applications with ease. By using Angular CLI, you can scaffold out new projects, generate components, services, and much more. However, installing Angular CLI with a specific version can be a bit tricky if you are not familiar with the process. That’s why we have put together this guide to help you through every step of the installation process.
Check the Current Version
Before installing a specific version of Angular CLI, it is important to check the current version installed on your system. This will help you determine whether you need to upgrade or install a specific version. Open your terminal or command prompt and run the following command:
Step 1: Open the Terminal or Command Prompt
The first step is to open the terminal or command prompt on your system. This is where you will enter the commands to check the current version of Angular CLI. On Windows, you can open the command prompt by pressing the Windows key + R, typing “cmd” in the Run dialog, and pressing Enter. On macOS or Linux, you can open the terminal by searching for “terminal” in the applications menu.
Step 2: Run the Command
Once you have the terminal or command prompt open, you can run the command to check the current version of Angular CLI. Type the following command and press Enter:
ng –version
This command will display the version number of Angular CLI installed on your system. It will also show other information such as the version of Node.js and npm (Node Package Manager) installed.
By checking the current version, you can ensure that you are installing the correct version of Angular CLI.
Uninstall Existing Angular CLI
If you have an existing Angular CLI installation, it is recommended to uninstall it before installing a specific version. This will prevent any conflicts or compatibility issues. To uninstall Angular CLI, follow these steps:
Step 1: Open the Terminal or Command Prompt
Just like in the previous section, you need to open the terminal or command prompt on your system.
Step 2: Run the Command
Once you have the terminal or command prompt open, you can run the command to uninstall Angular CLI. Type the following command and press Enter:
npm uninstall -g @angular/cli
This command will uninstall Angular CLI from your system. The “-g” flag stands for global, which means it will uninstall Angular CLI from the global scope, making it unavailable for all projects.
Step 3: Verify the Uninstallation
After running the uninstall command, it is a good practice to verify whether the uninstallation was successful. You can do this by running the following command:
ng –version
If the uninstallation was successful, the command should return an error message indicating that Angular CLI is not installed.
By uninstalling the existing Angular CLI, you can ensure a clean installation of the specific version.
Choose the Specific Version
Now that you have checked the current version and uninstalled any existing installations, it’s time to choose the specific version of Angular CLI you want to install. You can find the list of available versions on the official Angular CLI GitHub repository. Take note of the version number you want to install.
Step 1: Visit the Angular CLI GitHub Repository
Open your web browser and visit the official Angular CLI GitHub repository. You can find it at “https://github.com/angular/angular-cli”.
Step 2: Explore the Releases
Once you are on the Angular CLI GitHub repository page, navigate to the “Releases” section. This is where you will find the list of available versions.
Step 3: Choose the Version
Browse through the list of available versions and choose the one that suits your needs. Take note of the version number, as you will need it in the next section.
By choosing the specific version, you can ensure that you are installing the exact version of Angular CLI you desire.
Install the Specific Version
With the specific version chosen, you can now proceed to install it. Follow these steps to install the specific version of Angular CLI:
Step 1: Open the Terminal or Command Prompt
As mentioned earlier, open the terminal or command prompt on your system.
Step 2: Run the Command
Once you have the terminal or command prompt open, you can run the command to install the specific version of Angular CLI. Type the following command and press Enter:
npm install -g @angular/cli@
Replace “” with the version number you chose in the previous section. For example, if you want to install version 10.1.0, the command should look like this:
npm install -g @angular/cli@10.1.0
The installation process will begin and may take a few minutes. It will download the specific version of Angular CLI from the npm registry and install it globally on your system.
Step 3: Verify the Installation
After the installation is complete, it is always a good practice to verify whether the installation was successful. To verify the installation, run the following command:
ng –version
The command should display the installed version number of Angular CLI. Make sure it matches the specific version you installed.
By following these steps, you will successfully install the specific version of Angular CLI.
Troubleshooting
In case you encounter any issues during the installation process, here are a few troubleshooting tips:
Make sure you have the latest version of Node.js installed
Angular CLI requires Node.js to be installed on your system. Make sure you have the latest version of Node.js installed by visiting the official Node.js website and downloading the latest stable version.
Check your internet connection
Ensure that you have a stable internet connection while downloading and installing Angular CLI. A slow or intermittent internet connection can cause the installation process to fail or take longer than expected.
Clear your npm cache
If you are experiencing issues with the installation, clearing your npm cache might help. Run the following command to clear the npm cache:
npm cache clean –force
This command will clear the cache and force npm to download the necessary packages again during the installation process.
Consult the official Angular CLI documentation
If the issue persists, consult the official Angular CLI documentation for more troubleshooting tips and solutions. The documentation provides detailed information on common issues and how to resolve them.
Seek help from the Angular community
If you are still unable to resolve the issue, don’t hesitate to seek help from the Angular community. There are various forums, discussion boards, and social media groups where you can ask questions and get assistance from experienced developers.
By following these troubleshooting tips, you can overcome any installation issues and successfully install the specific version of Angular CLI.
