生成webapp时未定义Yo错误编码

Question

按照http://www.youtube.com/watch?feature=player_embedded&v=zBt2g9ekiug大约3分钟后,当我从cmd行运行yo webapp时,我得到以下内容.谁看过这个吗？

   C:\Users\L\AppData\Roaming\npm\node_modules\generator-webapp\node_modules\cheeri
o\node_modules\entities\index.js:36
        return encode[level](data);
               ^

在使用最新的Yomen版本的教程时,我遇到了同样的问题.实体库中存在拼写错误您可以手动修复以完成教程:

打开文件有错误(在您的情况下为C:\ Users\L\AppData\Roaming \npm \node_modules\generator-webapp \node_modules\cheerio \node_modules\entities\index.js)并将变量名从逆转换为编码

var decode = levels.map(function(l){ return l.normal; }),
    decodeStrict = levels.map(function(l){ return l.strict; }),
    inverse = levels.map(function(l){ return l.inverse; });

至

var decode = levels.map(function(l){ return l.normal; }),
    decodeStrict = levels.map(function(l){ return l.strict; }),
    encode = levels.map(function(l){ return l.inverse; });
