command line - notification - npm instala múltiples nombres de paquetes

browsersync gulp js

Question

¿Qué hace cuando ejecuto este comando?

npm install --save-dev package1 package2

Definitivamente no está instalando múltiples paquetes, pero parece ser esencial. (Por ejemplo https://www.browsersync.io/docs/gulp )

Para mí arroja los siguientes ERR:

Answer 1

Definitivamente no está instalando paquetes múltiples

¿Por qué? Está instalando package1 y package2 y marcándolos como devDependencies con --save-dev .

Como se indica en la documentación , puede combinar múltiples argumentos e incluso múltiples tipos de argumentos. En su caso, está combinando 2 nombres de paquetes publicados en el registro.

Answer 2

Guardar como dependencias:

npm i -S package1 package2

Guardar como dependencias de desarrollo:

npm i -D package1 package2
