如何更改NodeJS CLI提示符

Question

I want to change the prompt for the nodejs cli prompt. I looked around but didn't find an solution.

Some people talked about a prompt module. But var p = require('prompt'); just gives me an error

Answer 1

You need to add the dependency to your project.

[sudo] npm install prompt [--save]

--save will add it to your package.json

Answer 2

My guess is that you are not using the p.start(); command. So try out this simple example

  var prompt = require('prompt');


  prompt.start();

  // 
  // Get two properties from the user: username and email 
  // 
  prompt.get(['username', 'email'], function (err, result) {
    // 
    // Log the results. 
    // 
    console.log('Command-line input received:');
    console.log('  username: ' + result.username);
    console.log('  email: ' + result.email);
  });

Also if you are new to npm and node in general, start your projects with

npm init

that creates your package.json file in which you provide your project's dependencies

the following command installs prompt for node and saves it in your package.json

npm install -S prompt
