Install Angular 9 on Windows 10

1. Install Node.js

We need NPM to install Angular CLI. To install Node.js on your system and NPM will install with Node.js.

我们需要NPM来安装Angular CLI。因此要在系统上安装Node.js，NPM将与Node.js一起安装

To install Node.js, go to the official Node.js website, download the latest version and install it.

After the installation, check the versions using the below commands.

node -v
npm -v

This will show the installed versions of Node.js and NPM.

Note: If you are really a beginner in this field, the guide Steps to install Node.js and NPM on Windows 10 will help you.

2. Install Angular CLI

Angular CLI helps us to create projects, generate application and library code, and perform a variety of ongoing development tasks such as testing, bundling, and deployment.

Angular CLI帮助我们创建项目，生成应用程序和库代码，并执行各种正在进行的开发任务，例如测试，构建和部署

It can simply be installed using NPM. So first, open our Command Prompt / Powershell and install the Angular CLI with the below command.

只需使用NPM即可安装。因此，首先打开我们的命令提示符/ Powershell，然后使用以下命令安装Angular CLI

npm install -g @angular/cli

This will ask you a question.

Would you like to share anonymous usage data with the Angular Team at Google under Google’s Privacy Policy at https://policies.google.com/privacy? For more details and how to change this setting, see http://angular.io/analytics.

You can either agree or disagree with the question. Press y and Enter for agreeing and n and Enter if you are disagreeing. This answer won’t affect the Angular installation

3. Creating a New Angular Application

You have successfully installed Angular CLI on our system and now you can set up a workspace for Angular projects in the system and create a new app. This can be done with the below command.

您已经在我们的系统上成功安装了Angular CLI，现在您可以在系统中为Angular项目设置工作区并创建一个新应用。可以使用以下命令完成此操作

ng new awesome-project

This will ask you two questions.

1. Would you like to add Angular routing?

press y if you are preferring t to create a multi-page website. Otherwise choose n.

2. Which stylesheet format would you like to use?

Choose any stylesheet format that you are familiar with. Here I chose CSS.

4. Running Our App

Now, the app you created can be run using ng serve command.

现在，您可以使用ng serve命令运行您创建的应用程序

cd awesome-project
ng serve --open

This launches the server, watches our files, and rebuilds the app as we make changes to those files. The –-open (or just -o) option automatically opens our browser to the address http://localhost:4200.

这将启动服务器，监视我们的文件，并在我们对这些文件进行更改时重构应用程序。––open（或仅-o）选项会自动将浏览器打开到地址http://localhost:4200

TechoTip: We recommend using Visual Studio code as the source-code editor for working with Angular projects.

Summary

So, we have discussed the steps to install Node.js on our Windows 10 system and installation on Angular 9 using NPM(Node Package Manager).
