How to resolve gulp dependencies while creating a NPM package - node.js

Question

I have a nodeJs application(demo) which using commander package to take command line argument and using gulp for
build
docs
test
coverage
This functionality is working fine but Now I need to move this application as a NPM Package.
Changes are done according to according NPM Package but when I install this as NPM package npm install ../demo/ from local location.
It asks for following gulp dependencies: -
Cannot find module gulp
Cannot find module gulp-load-plugins
Cannot find module del
Cannot find module gulp-plumber
Cannot find module gulp-eslint
Cannot find module babel-eslint
Cannot find module gulp-debug
Cannot find module gulp-sourcemaps
Cannot find module gulp-babel
Every time I go back to the npm package(which i created) directory and run the command which occurs as an error like npm install gulp --save-dev and npm install del --save-dev and so on.
I also defined these dependencies in package.json but it is still throwing errors.
Is there any way to resolve this issue.
package.json
{
"name": "demo",
"version": "0.0.1",
"description": "",
"main": "./dist/index.js",
"license": "SEE LICENSE IN LICENSE.md",
"keywords": [],
"scripts": {
"build": "gulp build",
"coverage": "gulp coverage",

"test": "gulp test"
},

"btoa": "^1.1.2",
"superagent": "^2.1.0"
},
"engines": {
"node": ">=4.0.0"
}
}
I put all the things in dependencies. I tried that way but having same problem.
npm install ../demo/
npm WARN package.json demo_project#1.0.0 No description
npm WARN package.json demo_project#1.0.0 No repository field.
npm WARN package.json demo_project#1.0.0 No README data
> demo#0.0.1 prepublish /work/demo
> gulp build
[16:53:33] Local gulp not found in ~/work/demo
[16:53:33] Try running: npm install gulp

Although the documentation doesn't mention it, npm install folder only installs dependencies and not devDependencies. This may be a little bit confusing as running npm install inside the package folder installs both dependenciesand devDependencies.
So try to install gulpand all the rest as npm install --save gulp (not
--save-dev)
UPDATE: after adding package.json:
everything under devDependencies in your package.json should be under dependencies:
