通过npm或yarn自动生成vue组件的方法示例

npm install chalk --save-dev 
yarn add chalk --save-dev

// template.js
module.exports = {
 vueTemplate: compoenntName => {
  return `<template>
 <div class="${compoenntName}">
  ${compoenntName}组件
 </div>
</template>

<script>
export default {
 name: '${compoenntName}'
}
</script>

<style scoped lang="stylus" rel="stylesheet/stylus">
.${compoenntName} {

}
</style>

`
 },
 entryTemplate: `import Main from './main.vue'
export default Main`
}
