Yo error encode not defined when generating webapp

Question

I get the following when I run yo webapp from the cmd line after following http://www.youtube.com/watch?feature=player_embedded&v=zBt2g9ekiug to about 3 minutes. Has anyone seen this before?

   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

One workaround is to use the cg-angular yeoman generator:

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

Obviously not ideal if you're following a tutorial though.

Answer 2

I had same issue when follow tutorial with latest Yomen version. There is typo error in entities library that You can manually fix to complete tutorial:

Open file with error (in your case C:\Users\L\AppData\Roaming\npm\node_modules\generator-webapp\node_modules\cheerio\node_modules\entities\index.js ) and change variable name from inverse to 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; });

To

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; });

Also happening in OSX for angular generator:

    return encode[level](data);
           ^

Answer 4

The Node module entities just released a new version breaking a dependency (cheerio) of yeoman.

Error seems to originate to cheerio. Issue opened here https://github.com/MatthewMueller/cheerio/pull/382
