Gulp build does not install dependencies automatically?

Question

I use gulp to build my javascript application. I have some dependencies declared in the package.json file, for example:

"dependencies": {   "flux": "^2.0.1",   "keymirror": "~0.1.0",   "object-assign": "^1.0.0",   "react": "^0.13.1",   "dropzone": "^4.0.1",   "lodash": "^3.6.0" } 

When I run gulp build, it always prompt me some dependency cannot be found unless I manually run npm install lodash for example.

Is there a way to have gulp run npm install automatically?

Answer 1

Run npm install --save-dev command to resolve all dependencies.

Here is link to documentation with --save-dev parameter description: https://docs.npmjs.com/cli/install
