'npm add'和'npm install --save'之间的区别？

Question

I've searched through the web and still can't get if there is any difference between npm add <package> and npm install --save <package> .

Thanks.

Answer 1

npm install and add are aliases. The --save option is deprecated.

Since NPM 5, packages are saved automatically; there is no --save option .

Answer 2

add is just an alias for install .

So the only difference is --save , which modifies package.json with the dependancy.

 $ npm add --help npm install (with no args, in package dir) npm install [<@scope>/]<pkg> npm install [<@scope>/]<pkg>@<tag> npm install [<@scope>/]<pkg>@<version> npm install [<@scope>/]<pkg>@<version range> npm install <folder> npm install <tarball file> npm install <tarball url> npm install <git:// url> npm install <github username>/<github project> aliases: i, isntall, add common options: [--save-prod|--save-dev|--save-optional] [--save-exact] [--no-save]
