How to configure Angular development environment in windows environment

Node.js

Installation

Node.js is more convenient to install, go directly to Node.js Official download, and then follow the steps to install it

You can install it in any directory, such as

D:\nodejs\

Node.jscomes with itnpm , so there is no need to install it

Open the cmd terminal and use the following command to check whether the Node.js installation is successful:

node -v
npm -v

If a version number appears, indicate Node.jsInstallation successful

Configuration

Configure prefix and cache

Use the following command to view the configuration of npm

npm config ls

You can see that npm initially placed the downloaded dependency packages and cache in the C drive. Obviously this is not appropriate, but you can configure these two directories

npm config set prefix "D:\nodejs\node_global"
npm config set cache "D:\nodejs\node_cache"

Configure environment variables

Right-click "Computer"->"Properties"->"Advanced System Settings"->"Environment Variables"

In System Variables, setNODE_PATH, the value is

D:\nodejs\node_global\node_modules\

In user variables, modify path and add

D:\nodejs\node_global\

Change npm’s mirror source

Since the initial source of npm is from abroad, the speed may be a bit slow

You can configure Taobao’s mirror cnpm here, and ## will be used later Change the command of #npm to cnpm

npm install -g cnpm --registry=https://registry.npm.taobao.org

If you choose Taobao’s

cnmp mirror, you should set it up to ensure normal downloading of the tool

ng set --global packageManager = cnpm

Typescript

---

Execute the following command

npm install -g typescript typings

Check the version number

tsc -v

Angular-cli

##angular -cli

It is an official build tool of the Angular framework. The core is webpack, and npm as a dependent package. Execute the following command

npm install -g @angular-cli

Check version number

hello-world

folder <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:cpp;toolbar:false;">ng serve</pre><div class="contentsignin">Copy after login</div></div>The Angular service listens to the

4200

port by default, open the browser, Enter <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:cpp;toolbar:false;">localhost:4200</pre><div class="contentsignin">Copy after login</div></div> or enter the following command to directly open the default browser
