Angular is a powerful front-end framework that enables developers to build robust and dynamic web applications. However, when working with Angular, it's important to ensure that you have the correct version installed. In this article, we'll explore how you can install a specific version of Angular and provide examples of how to do it.
Installing a Specific Version of Angular
To install a specific version of Angular, you need to run a command in your terminal or command prompt. The command you need to run will depend on the package manager you are using. Here are the commands for installing specific versions of Angular with two commonly used package managers, NPM and Yarn:
- NPM: npm install @angular/cli@{version number}
- Yarn: yarn add @angular/cli@{version number}
In these commands, replace {version number} with the version of Angular you want to install. For example, to install version 10.0.0 of Angular, you would run the following command:
- NPM: npm install @angular/cli@10.0.0
- Yarn: yarn add @angular/cli@10.0.0
After running this command, your machine will start installing the specified version of Angular. This process may take a few minutes, depending on the version you are installing.
Creating a New Angular Project with a Specific Version
Once you have installed the specific version of Angular, you can create a new project using the same version by running the following command in your terminal or command prompt:
- ng new {project name} –version={version number}
Replace {project name} with the name of your project and {version number} with the version of Angular you want to use. For example, to create a new Angular project named "my-project" using version 10.0.0 of Angular, you would run the following command:
- ng new my-project –version=10.0.0
After running this command, Angular will create a new project with the specified version.
Upgrading an Existing Angular Project to a Specific Version
If you already have an existing Angular project and want to upgrade it to a specific version, you can do it using the following steps:
- Update the package.json file
Open the package.json file in your project and add the following line under the dependencies section:
"@angular/cli": "{version number}"
Replace {version number} with the version of Angular you want to upgrade to.
- Delete the node_modules folder
Delete the node_modules folder in your project. You can do this by running the following command in your terminal or command prompt:
- rm -rf node_modules
Note: This command is for MacOS and Linux. If you are using Windows, use the following command instead:
- rmdir /s node_modules
- Install the updated packages
Run the following command in your terminal or command prompt to install the updated packages:
- npm install
After running these steps, your existing Angular project should now be updated to the specified version of Angular.
Conclusion
In this article, we have explored how to install a specific version of Angular and provided examples of how to do it using NPM and Yarn. We have also seen how to create a new Angular project with a specific version and how to upgrade an existing project to a specific version. By following these steps, you can ensure that you are working with the correct version of Angular, which can help avoid compatibility issues and ensure the best performance and stability for your Angular applications.

Let's dive a bit deeper into some of the topics that were discussed in the previous article.
- Benefits of Installing a Specific Version of Angular
One of the key benefits of installing a specific version of Angular is to ensure that your applications will work correctly with the libraries and dependencies that they rely on. Different versions of Angular may behave differently and have updated dependencies, which can lead to incompatibility issues if your application relies on a specific version. By installing a specific version, you can also ensure that your application will have optimal performance and stability.
In addition, developers may need to install specific versions of Angular to maintain backwards compatibility with older applications that were written using older versions of Angular. This is especially important if you are working on an existing application that cannot be easily updated to the latest version of Angular.
- Creating a New Angular Project with a Specific Version
When creating a new Angular project with a specific version, it's important to specify the correct version to ensure that the project is using the intended version of Angular. By specifying the version during project creation, you can ensure that the dependencies and libraries used in the project are compatible with the specified version of Angular.
- Upgrading an Existing Angular Project to a Specific Version
Upgrading an existing Angular project to a specific version can be more challenging than creating a new project from scratch. This is because upgrading an existing project requires updating the dependencies and libraries that the project relies on, which can affect the compatibility and performance of the project.
To ensure a smooth upgrade, it's important to thoroughly test the new version of Angular with your existing code to identify any potential incompatibility issues. Developers should also be aware of any deprecated APIs or functions that may have been removed in the new version of Angular, which may require code modifications to maintain backwards compatibility.
In conclusion, installing a specific version of Angular can help ensure the compatibility and stability of your applications. By following the steps outlined in the previous article, developers can efficiently install and upgrade to specific versions of Angular and build reliable and high-performance web applications.
