First step: Download Nodejs and install
Official: https://nodejs.org/en/, I chose the long-term support version v4.47, installation as long as the next step is OK
After the installation is complete, you can use CMD (win+r and then enter CMD entry) to test if the installation is successful. Method: Enter node-vunder CMD, the version prompt is complete the installation of Nodejs.
We open the installation directory:
Discover the Nodejs directory there is a node.exe, what is it for?
Step Two: NPM installation
Before v0.63, in the node installation process, the actual need to install NPM, to v0.63 when Ndejs has integrated NPM, so you do not have to consider NPM installation problems. You can also use the cmd command line to enter "Npm-v" to test for successful installation
Step three: Run the test sample
Create a cs.js file with the editor and place it in the installation directory (not required)
The sample code is as follows:
1 var str= "Hello"; 2 console.log (str);
On the cmd command line, enter the command as follows:
Run Result: Hello
Note: Enter node in the cmd command line, enter node development mode, exit as?
Fourth step: Create New Node_cache, Node_global, and set environment variables

Sublime Text3 node. JS Development Environment Configuration
First step: Download plugin Sublimetext-nodejs
- Download compression packs directly on GitHub
Address: Https://github.com/tanepiper/SublimeText-Nodejs
Download the package directly and extract it to the sublime text directory and rename it to Nodejs. See where the package directory can be accessed directly from the preferences--> browse packages in the menu bar.
Use git commands to download to the package directory (such as Git clone Https://github.com/tanepiper/SublimeText-Nodejs "E:\ProgramFiles\Sublime Text 3\data \packages\nodejs ")
Step two: Modify the corresponding values
To modify the compilation options, in the Nodejs directory under the package directory, open the Nodejs.sublime-build
有2个地方需要修改,一个是编码,为了避免乱码,将代码 "encoding": "cp1252" 改为 "encoding": "utf8" ;另外一个是cmd命令,本身如果只是想简单的运行nodejs程序的话,windows下面的cmd可以直接 "cmd": ["node", "$file"]。
Open the file "nodejs.sublime-settings" and change the code "Node_command": false to "Node_command": "C:\\Program Files\\nodejs\\ Node.exe " , change the code " Npm_command ": false to " Npm_command ":" C:\\Program Files\\nodejs\\npm.cmd " , Save File
After restarting sublime text, the configuration is complete. Let's write a short piece of code to verify that it works.
1 varHTTP = require (' http ');2 3 varOS = require (' OS ');4 5Http.createserver (function(Request, response) {6 7Response.writehead, {' Content-type ': ' Text/plain '});8 9Response.End (' Hello world\n '); }). Listen (3000);Ten OneConsole.log (' Server running at Http://127.0.0.1:3000/');
Ctrl+b The code is compiled, the Sublime text window will display
Server running at Http://127.0.0.1:3000/
If a previously running node process is in progress, the node process will be killed first, and then node can be started, as shown below:
Success: The process "Node.exe" has been terminated with a PID of 154588.
Server running at Http://127.0.0.1:3000/
In this case, the server is started successfully, open the browser, enter Http://127.0.0.1:3000/, the page shows Hello World is normal interaction.
(My Nodejs is installed in C:/Program Files/nodejs)
