Is the choice in the devel category

One installation, one step

Download the Selected Package

 

At last, whether to create the desktop icon and the Start menu icon are displayed. Use the default icon and click Finish.

 
4. Find the binfolder under cygwin's installation folder and run ash.exe

Enter./rebaseall-V

Start resetting all

5. Download and install node. js
Run cygwin Terminal

Enter wget http://nodejs.org/dist/node-v0.4.7.tar.gzto download the file in the command line.

Enter

Enter the tar xf node-v0.4.7.tar.gz to decompress the file

Input the CD node-v0.4.7.tar.gz to change the working directory

Enter./configure Configuration

Configuration successful

Input make to compile

Start Compilation

Compilation successful. A prompt is displayed.

Enter make install to install

If the installation is successful, a prompt is also displayed.

Enter node -- vesion to view the node. js version.

If v0.4.7 is displayed, the installation is successful.

Enter exit to exit

6. Set DNS

In the installation path, manually create a file named resolv. conf under D: \ cygwin \ etc.

Enter the content

7. Test whether node. js can be run
Create example. js in UTF-8 format under the c: \ cygwin \ directory

The above code is described below:

Line 1: The module HTTP that comes with node. js needs to be assigned to the variable HTTP.

Line 3 (out of brackets): Use the HTTP module method createserver ()

Row 6: This method returns an object. This object has a method called listen (), which is used to listen to a port. Therefore, three rows (out of brackets) are returned) and six rows are created to listen to port 8888 Server

Three rows (in parentheses): An anonymous function has two parameters: one request and one response.

Line 4: when receiving the request, use the response. writeHead () function to send an http status 200 and content type of the http header (content-type)

Row 5: You can use the response. write () function to send the text "Hello World" in the http body and use the response. end () function to complete the response. Response. end (text) is used for merging.

Run Cygwin Terminal and enter node/example. js

It indicates that the server is running on port 8888.

Do not close cygwin. Open your browser and visit http: // 127.0.0.1: 8888/To see if the hello world page is displayed.

Since then, the Node. js environment has been built.

Is it very simple?
