Question

我在跟随http://www.youtube.com/watch?feature=player_embedded&v=zBt2g9ekiug到约3分钟之后从cmd行运行yo webapp时得到以下内容。有没有人见过这个？

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

Answer 1

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

打开包含错误的文件（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）并将变量名称从inverse更改为encode

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; });

到

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; });

Answer 2

一种解决方法是使用cg-angular yeoman生成器：

sudo npm install -g generator-cg-angular
yo cg-angular

如果您正在学习教程，那么显然不理想。

Answer 3

在OSX中也发生角度生成器：

/usr/local/lib/node_modules/generator-angular/node_modules/yeoman-generator/node_modules/cheerio/node_modules/entities/index.js:36
    return encode[level](data);
           ^

Answer 4

Node模块实体刚刚发布了一个新版本，打破了yeoman的依赖（cheerio）。

Answer 5

错误似乎源于cheerio。问题在此处开始https://github.com/MatthewMueller/cheerio/pull/382
