Grunt doesn't see my devDependency module

Question

I installed this:

https://www.npmjs.com/package/derequire

with

npm install derequire --save-dev

It appeared in the package.json file

"devDependencies": {
    "derequire": "^2.0.3",

but when in Gruntfile.js I do:

grunt.loadNpmTasks('derequire');

I get the following error: Local Npm module "derequire" not found. Is it installed?

Other dependencies work fine.

I noticed that other dependencies are prefixed with 'grunt-' (eg: 'grunt-contrib-concat'). Does it mean that I can't use this NPM derequire in grunt? How can I enable it?

Answer 1

grunt.loadNpmTasks('derequire'); doesn't work because it's supposed to be used with Grunt plugins. See the reference . You can't just use it with regular NPM packages.

For a list of Grunt plugins, take a look here .
