Error npm install won t install devDependencies

Question

For some reason when I run npm install it won't install devDependencies. If I run npm install --dev devDependencies are installed. I don't understand why npm install doesn't install devDependencies too, but installs only dependencies. What could be the reason? How can I fix it?

Maybe something is wrong with my package.json? It is listed below if it may be helpful:

{
  "name": "try-brunch",
  "version": "0.1.0",
  "private": "true",
  "devDependencies": {
    "brunch": "^2.0.4",
    "cssnano-brunch": "^1.1.5",
    "javascript-brunch": "^1.8.0",
    "sass-brunch": "^1.9.2",
    "uglify-js-brunch": "^1.7.8"
  },
  "dependencies": {
    "jquery": "^2.1.4"
  }
}

Hello @kartik,

Try:

npm install --only=dev

If you are worried that your package.json might be incorrect, best thing to do is this. Create a new folder, and run:

npm init --yes

Then:

npm install --save-dev brunch@^2.0.4
npm install --save-dev cssnano-brunch@^1.1.5
npm install --save-dev javascript-brunch@^1.8.0
npm install --save-dev sass-brunch@^1.9.2
npm install --save-dev uglify-js-brunch@^1.7.8
npm install jquery@^2.1.4 --save

If stiil not resolved:

Check your npm configuration:

npm config list

npm gets its config settings from the command line, environment variables, and npmrc files. So check environment variables, and the npmrc file.

Hope it helps!!
Thank you!!
