This article mainly introduces "the method of configuring and installing the node.js environment under the windows system". In the daily operation, I believe that many people have doubts about the method of configuring and installing the node.js environment under the windows system. The editor consulted all kinds of materials and sorted out the simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts about the configuration and installation of the node.js environment under the windows system. Next, please follow the editor to study!

Step 1: download the installation file

Download address: official website https://nodejs.org/en/download/

What's used here is

Step 2: install nodejs

When the download is complete, double-click

Node-v6.9.1-x64.msi, start installing nodejs, which is installed under c:\ program files\ nodejs by default

Step 3: install the relevant environment

Open the c:\ program files\ nodejs directory and you will find that it comes with npm. You can install it directly with npm.

Open windows with dos window win+r, enter cmd, and enter enter

Type the command: cd c:\ program files\ nodejs

Now begin to install the relevant environment

Type the command: npm install express-g enter and wait for express.

Type the command: npm install jade enter to wait for the installation of jade.

Type the command: npm install mysql enter to wait for the installation of mysql.

. What components to install depends on the building requirements of the environment

By default, the above components are installed in the c:\ program files\ nodejs\ node_modules folder, which is also the automatic lookup path for nodejs-related components.

Step 4: create a project

If you find that there are no express and express.cmd files in the c:\ program files\ nodejs directory after installing the above components, execute the command npm install express-generator

(because the default installation of express is the latest version, it is already the version of 4.x.x. In the latest version of express4.0+, command tools are separated, so express-generator must be installed)

Now there is express.

The express command only works when installed globally!

So use npm install express-g when installing express

Or modify the global path directly:

Npm config set prefix "c:\ program files\ nodejs"

Npm config set cache "c:\ program files\ nodejs\ cache" (set up the cache directory first)

Type: express myapp (myapp is a random project name)

You will find an extra c:\ program files\ nodejs\ myapp directory

By default, it is automatically created in

Copy node_modules to myapp

After setting up the environment, let's do a demo test!

Create a new helloworld.js under myapp

Var http = require ("http"); http.createserver (function (request, response) {response.writehead (200,{ "content-type": "text/plain"}); response.write ("hello world"); response.end ();}) .customers (8888); console.log ("nodejs start listen 8888 port!")

Go to the node.js command prompt command window and go to the c:\ program files\ nodejs\ myapp directory

Type node helloworld.js

Open the address

Discovery output:

Hello world

Global mode and local mode installation issues are resolved:

Global mode:

After installing express and express-generator, go to the path:

C:\ program files\ nodejs generates two files, express and express.cmd.

Local mode:

After installing express and express-generator, there are no express and express.cmd files generated in the path: d:\ tools\ nodejs. And in the path:

Under c:\ program files\ nodejs\ node_modules, there is a .bin (generated when installing express-generator) that contains two files, express and express.cmd.

Then add: C:\ program files\ nodejs\ node_modules\ .bin to the system environment variable path

Try to execute again:

C:\ program files\ nodejs > express-v

At this point, the study of "the method of configuring and installing the node.js environment under the windows system" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
