npm install won't install devDependencies
Question
On windows for some reason when I run npm install it won't install devDependencies . AFAIK it should. 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"
}
}

As of now you could use:
npm i --also=dev

In my case, the problem was that I had the NODE_ENV variable set to production in the same terminal session I ran npm install .
For my build to run properly I was not allowed to change the value of NODE_ENV so I forced npm to install all the dependencies by adding the --production=false flag to it: npm install --production=false as mentioned in the docs .
If you don't need NODE_ENV to be set to production you can simply type export NODE_ENV=development to your terminal to overwrite its value and run npm install again.

As @Ale told, we can use npm i -D <some_module_name> or npm i --save-dev <some_module_name> now . It seems command was changed at some point of node version. Offical ( npm dependencies and devDependencies ) says following.
When you add the -D flag, or --save-dev, you are installing it as a development dependency, which adds it to the devDependencies list.
