npm install multiple package names

Question

What does it do when I run this command:

npm install --save-dev package1 package2

It is definitely not installing multiple packages, but it looks to be essential. (For example https://www.browsersync.io/docs/gulp)

For me it throws following ERRs:

So you state that "It is definitely not installing multiple packages" - what does it do in your case? What's the console output after running that command? – Zhang

It gives a long list of error, that it does not produce, while installing packages individually. See updated post. – Hailstorm

Do you mean errors? Those packages need Python, install Python with proper version and re-install, you won't see those errors again. – City

Answer 1

It is definitely not installing multiple packages

Why? You're installing package1 and package2 and marking them as devDependencies with --save-dev.

As stated in the documentation, you may combine multiple arguments, and even multiple types of arguments. In your case, you're combining 2 package names published on the registry.

Highland

Stangely for me it throws multiple errors not even revolving around the installed packages. If I try to install it one by one, everything is OK. See my updated post. – Hailstorm

Answer 2

Save as dependencies:

npm i package1 package2

Save as dev-dependencies:

npm i -D package1 package2

npm i --save-dev package1 package2

Answer 3

npm install --save module1 module2

Example: npm install --save morgan chalk errorhandler lusca dotenv path mongoose

The above command will install the latest versions of morgan, chalk, errorhandler, lusca, dotenv, path and mongoose.

Answer 4

The other answers here do not appear to answer the question. Specifically, doing an npm install --save-dev p1 p2 p3 does not cause p2 and p3 to be stored in my package.json file.

The following line installs all packages + saves it in dev dependencies for me:

for i in 'package1' 'package2'; do npm install --save-dev "$i"; done

I'm on Windows and use Cygwin, but this works on *nix systems, too.

Somewhat unrelated but very important if using Cygwin: if you do use Cygwin, you need to add noacl to your mount options, or it will mess up your module permissions and cause Windows to freak out.

Answer 5

What I do is

npm i @tanstack/react-query @tanstack/react-query-devtools && npm i -D @tanstack/eslint-plugin-query

Here what I did was install all dependencies with npm i with space to separate packages and when I want to download dev dependencies I use && and npm i -D with space to install multiple dev dependencies packages.

Generate Rule

npm i package1 package2 .... && npm i -D devDependenciesPackage1 devDependenciesPackage2 ...

Indication
&& to separate dependencies with Dev Dependecies

... to indicate that you are add more package before && symbol
