进入工作目录 npm init

  return 'Hello ' + name + '!'
}

module.exports = hello

还没 npm 账户？注册

npm login  #或 npm adduser

注意：Logged in as honye on https://registry.npmjs.org/

如果设置了镜像会报错

is not in the npm registry

需要改回原先的

npm config set registry https://registry.npmjs.org/

npm publish

如果包名为 @honye/hello 这种 scoped package，需要

npm publish --access=public

npm install @honye/hello

const hello = require('@honye/hello')
const helloWorld = hello('world')
console.log(helloWorld)
