我yeoman发电机不会复制文件
问题描述：
我正在使用yeoman制作一个web应用程序，我被困在创建一个发电机。问题是它不会将文件复制到输出文件夹。我yeoman发电机不会复制文件
这里是我的代码：

我认为这个问题是在写作方法。我也想问下一步该去哪里？或者我通过了一个基本步骤去学习web dev
答
如果你格式化你的代码，你会看到writing函数没有做任何事情。它声明了一堆子函数，但不运行任何人。
我认为问题是你想要一个对象，而是写了一个函数：writing() {}而不是writing: {}。
我做了一个代码的快速修复，但没有测试出来。所以有可能是进一步的语法问题，但它应该大致是这样的：
'use strict';
var fs = require('fs');
var path = require('path');
var yeoman = require('yeoman-generator');
var yosay = require('yosay');
var chalk = require('chalk');

this.mkdir('app');
this.mkdir('app/css');
this.mkdir('app/sections');
this.mkdir('build');

this.pkg = require('../../package.json');

我做出了这些更改。 ..这是同一个问题......文件不会复制到新目录中 –
答
我删除了var做=异步（）和替换“this.prompt”被“退货。提示“ 大部分文件被复制...但仍有更多无效代码::
您是否收到任何错误？如果是这样，请分享它们。 –
没有错误...当我与yeoman一起运行时...提示方法工作原理：询问我是否想使用角度或jquery ...填充选项后...它只是在那里结束 –
