中文代码演示创建Node。js模块

　　参考: Creating Node.js modules创建 package.json 文件
　　因为打算创建公开模块, 因此按unscoped的建法。与 maven 不同，包名貌似不允许中文字符:$ npm init This utility will walk you through creating a package.json file. It only covers the most common items, and tries to guess sensible defaults.  See `npm help json` for definitive documentation on these fields and exactly what they do.  Use `npm install ` afterwards to install a package and save it as a dependency in the package.json file.  Press ^C at any time to quit. package name: (npm-module-demo) npm模块演示 Sorry, name can only contain URL-friendly characters. package name: (npm-module-demo) npm-module-demo-cn version: (1.0.0)  description:  entry point: (index.js) 入口.js test command:  git repository:  keywords:  author:  license: (ISC)  About to write to /Users/xuanwu/work/javascript-apps/npm-module-demo/package.json:  {   ＂name＂: ＂npm-module-demo-cn＂,   ＂version＂: ＂1.0.0＂,   ＂description＂: ＂＂,   ＂main＂: ＂入口.js＂,   ＂scripts＂: {     ＂test＂: ＂echo ＂Error: no test specified＂ && exit 1＂   },   ＂author＂: ＂＂,   ＂license＂: ＂ISC＂ }   Is this OK? (yes)创建入口文件
　　入口.js:exports.回应 = function() {   console.log(＂模块演示＂); }测试模块
　　首先需要发布模块到 npm. 但在运行npm publish时, 报错:npm ERR! code E401 npm ERR! 401 Unauthorized - PUT https://registry.npmjs.org/npm-module-demo-cn - You must be logged in to publish packages.
　　发现要先运行npm adduser, 创建用户账号.npm ERR! code E403 npm ERR! 403 Forbidden - PUT https://registry.npmjs.org/npm-module-demo-cn - you must verify your email before publishing a new package: https://www.npmjs.com/email-edit
　　还需验证电邮。之后发布成功.
　　新建测试目录后, 添加 test.js:var 演示 = require(＂npm-module-demo-cn＂)  演示.回应()
　　测试目录下安装模块: npm install npm-module-demo-cn
　　测试通过:$ node test 模块演示
