How to install only "devDependencies" using npm
node.jsNpmNpm Installpackage.jsonnode.js Problem Overview
I am trying to install ONLY the "devDependencies" listed in my package.json file. But none of the following commands work as I expect. All of the following commands install the production dependencies also which I do not want.
npm install --dev
npm install --only=dev
npm install --only-dev
I cannot think of any more ways of telling the npm to install the devDependencies alone. :(
node.js Solutions
Solution 1 - node.js
Check the NPM docs for install:
> With the --production flag (or when the NODE_ENV environment variable is set to production), npm will not install modules listed in devDependencies.
>
> The --only={prod[uction]|dev[elopment]} argument will cause either only devDependencies or only non-devDependencies to be installed regardless of the NODE_ENV.
Have you tried the following?
npm install --only=dev
Solution 2 - node.js
npm i -D
An optional short version.
Solution 3 - node.js
npm install thePackageName --save-dev
This works fine for me.
Solution 4 - node.js
As of npm version 7.10.0 you can omit certain types of dependencies, however you cannot omit "the" dependencies (production) anymore. That's why there is no solution for this problem anymore.
Solution 5 - node.js
The --only=dev option is no longer supported. To do the dev dependency install run npm install --production=false
Solution 6 - node.js
Running npm install, It will install all dependencies under devDependencies` or dependencies.
For installing and save packages as dev dependencies in package.json,
npm install package_name --save-dev or pass option -D
For installing all packages under devDependencies,
npm install --only=dev
For installing and save packages as prod or only dependencies in package.json,
npm install package_name --save-prod or pass option -P or npm install package_name
For installing all packages under dependencies or Prod dependencies,
set Environment variable NODE_ENV=production or pass it with the command NODE_ENV=production npm install or npm install --only=prod
Instead of using install in npm command like npm install you can just use i like npm i, short of install.
