Pierwsze dziwny błąd z chrząknięcie: Przedmiot Gruntfile.js ma metodę „spłaszczyć”

Question

otrzymuję ten dziwny błąd podczas próby uruchomienia chrząknięcie: TypeError: Object Gruntfile.js has no method 'flatten'

Jestem nowy node.js, npm, grunt, itp. Myślałem, że zrobiłem przyzwoitą instalację węzła, npm, chrząknięcie, ale może być coś przegapiłem. Czy istnieje sposób weryfikacji instalacji?

$ cat xx 
$ grunt 

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

Answer 1

Jak zostało napisane w https://github.com/gruntjs/grunt/issues/888dist w .gitignore

nadzieję, że pomoże

Answer 2

To wygląda jak jeden z twoich modułów Grunt próbuje użyć underscore.js ale nie jest zainstalowany. To powinno rozwiązać problem:

npm install underscore 

Albo jeszcze lepiej, dodać podkreślenia jako zależność rozwoju w swojej package.json:

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

Answer 3

Spróbuj ponownie zainstalować moduły węzła.

1. Usuń folder node_modules
2. Czy npm cache clean
3. Wykonaj npm install

Nadzieja to pomaga :)

Answer 4

Stwierdzili, że to działa, jak na https://github.com/gruntjs/grunt/issues/888

rm -rf node_modules/grunt 
npm install grunt 

To też powinno działać.
