Wie Sie einen seltsamen Fehler mit Grunzen: Object Gruntfile.js keine Methode ‚abzuflachen‘ hat

Question

Ich erhalte diese seltsame Fehler versucht Grunzen auszuführen: TypeError: Object Gruntfile.js has no method 'flatten'

Ich bin neu in node.js, npm, grunzen, usw. Ich dachte, ich hätte eine ordentliche Installation von Node, Npm, Grunt aber vielleicht habe ich etwas verpasst. Gibt es eine Möglichkeit, die Installation zu überprüfen?

$ cat xx 
$ grunt 

/home/cl/node_modules/grunt/node_modules/findup-sync/lib/findup-sync.js:33 
    }).flatten().uniq().value(); 
    ^

Answer 1

Wie in https://github.com/gruntjs/grunt/issues/888dist in Ihrem .gitignore

Hoffnung geschrieben, die

Answer 2

, die wie eine Ihrer Grunzen Module sieht versucht underscore.js zu verwenden, aber es ist nicht installiert. Dies sollte Ihr Problem beheben:

npm install underscore 

Oder noch besser, fügen Sie Strich als Entwicklungs Abhängigkeit in Ihrem package.json:

{ 
    <your existing stuff here> 
    "devDependencies": { 
    "underscore": "~1.5.2" 
    } 
} 

Answer 3

Versuchen Sie Knotenmodule neu zu installieren.

1. den node_modules Ordner löschen
2. Sie npm cache clean
3. npm install

hoffen, es hilft :)

Answer 4

gefunden, dass dies funktioniert, wie pro https://github.com/gruntjs/grunt/issues/888

rm -rf node_modules/grunt 
npm install grunt 

Das sollte auch funktionieren.
